berge@uchicago.edu

## Erez Berg

#### Associate Professor of Physics

The Berg group is interested in quantum matter. These are systems of many quantum particles, such as electrons, where inter-particle interactions have a fundamental effect on the physics. Understanding the possible behaviors of such systems is one of the major outstanding challenges in theoretical physics. We study the behavior of strongly correlated materials, such as high temperature superconductors. We are interested in exotic, topologically ordered states that can emerge in such systems. And we study how such states can be engineered by perturbing the system with either static or time-dependent fields. We use a variety of theoretical tools, from quantum field theory to numerical experiments.

Topics: Superconductivity, topological properties of matter, quantum dynamics of many-body systems

berry@uchicago.edu

## R. Stephen Berry

#### Professor Emeritus of Chemistry

The Berry Group studies the behavior of small clusters of atoms and molecules with an emphasis on the properties that distinguish them from bulk materials. From this, we move to the broader problem of matching macro and micro descriptions of phenomena, focusing on those for which the macro description loses its validity. Specifically, we look for “boundary sizes,” the maximum size of small systems for which such breakdown would be observable experimentally. We also have a continuing interest in dynamics of biomolecules and finite-time thermodynamics.

The Chin Group explores the quantum world at the lowest temperatures scientists can achieve—nearly a billionth of a degree Kelvin above absolute zero. Ultracold atoms and molecules are incredibly versatile tools for creating designer science experiments. Their versatility stems from the many forms of precise control that physicists have developed over recent years. This exquisite control has opened up a world of new opportunities for learning about fundamental physics as well as simulating complex systems of interest. We harness these powerful tools in order to learn about a wide variety of topics in modern science.

dinner@uchicago.edu

## Aaron Dinner

#### Professor of Chemistry

In the Dinner Group, we seek to develop our theoretical understanding of how complex biological behavior arises from molecular interactions. Because the defining properties of living systems (growth, movement, and directed response to environmental stimuli) rely on irreversible energy consumption and dissipation, much of our research centers on stochastic processes far from equilibrium. We quantitatively analyze experimental data on living systems, construct physical models to interpret the observed statistics, and implement algorithms for efficiently simulating the dynamics of such models.

dupont@cs.uchicago.edu

## Todd Dupont

#### Professor of Computer Science and Mathematics

My research deals with the analysis, evaluation, and construction of numerical methods to approximate the solutions of partial differential equations (PDEs). The question of how to make effective use of computers with multiple processing units is being investigated in several ways. I have recently produced several projects that involve decomposing the computational domain into subregions and organizing the computation so that the work on each of these subdomains can be done almost independently of one another. This work was for parabolic PDEs. I am studying its extension and have found that including adaptivity in numerical methods can make them more robust and efficient. Most simulations of time-dependent problems use adaptivity for the control of the time step, and substantial progress has been made by many people in understanding how to control the spatial mesh when approximating PDEs. I have worked on this for several years. I am also collaborating with physicists and mathematicians on questions related to instabilities and singularity development in the flow of fluids and pseudofluids.

Other projects underway in the group consider theories of the competitive solvation of polymers by mixed solvents, and systems with unusual phase diagrams. Work is progressing on conversion of our protein folding methods to ones using continuous statistical potentials that are applicable to Monte Carlo and molecular dynamics simulations.

wtirvine@uchicago.edu

## William Irvine

#### Associate Professor of Physics

The Irvine Group’s research spans soft condensed matter, optics, and topological fluid mechanics. Many phenomena in nature, from complex flows to the ways materials self-assemble and break, are underpinned by elegant geometric and topological mechanisms. One of our focuses is to seek and unravel the presence of these powerful interpretative keys that can be used to control the properties and assembly of materials. One example is the experimental and theoretical study of knotted fields. We seek to understand the physics and broader role of these fascinating excitations through experiments on knotted and shaped vortices in water as well as the mathematical structure of knots in fields. Similarly, geometric and topological constraints can provide a powerful interpretative key for understanding the behavior of many condensed matter systems, such as topological defects in ordered phases, the self-assembly of structures driven by the geometry of the constituents, and the relationship between chiral geometry and physical response.

#### Professor of Physics

A main theme of my research is the investigation of materials under conditions far from equilibrium. Such conditions give rise to a wealth of complex phenomena, while the insights gained can be used to control properties as well as design new classes of smart materials. One of our focuses is macroscopic granular matter, which exists almost exclusively under far-from-equilibrium conditions. The jamming/unjamming transition of macroscopic granular matter has become a model for understanding glassy behavior while also providing a path to discovering new types of high-efficiency particulate materials and enabling novel soft robotic systems. We also focus on the rheology of dense suspensions. Our third focus is drying-mediated self-assembly of nanoparticles, a process that we use to produce freestanding nanoparticle monolayer sheets. Such sheets can form ultrathin membranes with a tunable pore size.

wkang@uchicago.edu

## Woowon Kang

#### Professor of Physics

In recent years, my group has been pursuing research on the fractional quantum Hall effect in connection to topological quantum computation. Topological quantum computing is a fascinating interplay of topology, quantum field theory, physics of fractional quantum Hall effect, and theories of quantum computing. The fractional quantum Hall effect is presently the most promising platform among various candidate systems for a topological quantum computer. The global topological protection afforded by the fractional quantum Hall effect produces fault tolerance in a topological quantum computer. A topological quantum computer consequently becomes immune to the effects of local quantum decoherence. A fault-tolerant qubit can be constructed by taking advantage of the non-Abelian braiding statistics of elementary excitations (called anyons), which are thought to exist in certain exotic fractional quantum Hall states. Experimental goals include detection and manipulations of the postulated non-Abelian anyons in quantum interferometers that are constructed from high-quality semiconductor heterostructures.

Previously, we developed numerical techniques for looking at the nature of kinetic models intended to describe systems of this type.

I work on problems in quantitative biology, materials design, nonequilibrium dynamics, disordered systems, and theoretical computer science. Recent advances in computational intelligence have relied on the emergent collective behavior of simulated dynamical and statistical systems. I aim to implement such smart collective behaviors usually seen in “software” (error correction, neural networks, associative memory) directly into ”hardware” (biochemical reactions, self-assembly, robotics). Bringing such emergent learning and adaptive behavior back home to physical and chemical systems can shed light on underlying principles, reveal completely novel behaviors, and lead to new forms of designer matter.

s-nagel@uchicago.edu

## Sidney Nagel

#### Professor of Physics

My group is interested in understanding the bahavior of systems that are far from equilibrium. Such out-of-equilibrium behavior can occur in disordered materails, such as glasses which form from supercooled liquids, where thermal energy is insufficient to allow an exploration of the relevant phase space. Understanding the jammed or glassy state of matter relies to a large extent on simulations. In fluids and granular materials external energy input can drive the system into transient or steady-state dynamics that allows new structures and patterns to form that wold not exist in equilibrium. One can also find important far-from-equilibrium behavior in systems which remember certain aspects of how they have been formed or manipulated. The work in our lab tries to address these issues via experiment.

s-rice@uchicago.edu

## Stuart Rice

#### Professor Emeritus of Chemistry

Currently, my research interests lie in two broad areas: active control of quantum dynamical processes, and the properties of confined liquids. In the first category, the goal is to develop theoretical understanding of methods in order to achieve control of quantum dynamics, with specific application to selectivity of product formation in a chemical reaction. At present, the focus of the research effort is on extending the theory of control to reactions in condensed media and developing a version of the general theory that is useful when applied to large molecules. In the second category, the aim is to understand the structure and transport properties of confined liquids (e.g., liquids constrained to occupy a quasi–two-dimensional domain). Questions of interest are: How do the structures of the liquid and solid in a confined system, and the phase changes that occur in the confined system, depend on the intermolecular potential and geometry of the confinement? How do the structural and dynamical properties of quasi–one- and quasi–two-dimensional liquids differ from each other and those of a three-dimensional system? What interesting far-from-equilibrium structures (e.g., novel phases) are supported in confined liquids?

The research is problem oriented so that a wide range of proven and new experimental methods are applied or developed. Depending on the system and problem, the measurements may be taken with femtosecond time resolution or they may take days. Each experimental problem has a corresponding theory component that is done either within the group or through collaborations. Our research has always involved development of experimental methods, including advances in ultrafast lasers and nonlinear spectroscopy, pointillist and nonlinear microscopy, and image analysis.

david.schuster@uchicago.edu

## David Schuster

#### Assistant Professor of Physics

Quantum mechanical effects form the basis of nearly all modern electronics and methods of light generation. The discreteness of energy transitions underlies the remarkable stability of lasers and atomic clocks, which can be precise to an astonishing degree of 1e-17. It is used as the basis of nearly every standard of measurement, including voltage, resistance, current, temperature, and, soon, mass. It also provides the nonlinearity exploited by transistors. Interference is employed by the most exquisite modern sensors, including the SQUID, atomic magnetometers, and gravity gradiometers. Although these devices rely on quantum mechanics, they operate on classical signals and information. Systems that are fully quantum-mechanical could, in principle, exploit entanglement to solve certain problems exponentially faster than classical systems and enhance metrology. My group studies fully-quantum systems experimentally, employing a technique known as circuit quantum electrodynamics. In this method, microwave photons are manipulated by superconducting circuits that maintain quantum coherence. These circuits are readily manipulated and have the potential to interact with many quantum systems. In particular, I plan to use them as a "quantum bus" to explore other quantum systems and connect them together.

simonjon@uchicago.edu

## Jonathan Simon

#### Assistant Professor of Physics

My research interests span condensed matter physics, quantum optics, and atomic physics. A consistent theme in my work is the effort to understand how the wonderfully bizarre laws of quantum mechanics imbue materials with exotic properties. This is important both technologically and fundamentally, as emergent physics in strongly interacting quantum systems is truly the wild west of modern condensed matter physics. The tools of atomic physics provide an exciting new route to building and understanding quantum materials. Honed through decades of precision measurement work, these tools offer extraordinary control of laser-cooled atoms and a deep understanding of how such atoms interact with one another. My work employs this approach to build designer synthetic materials from cold atoms and probe their properties at the level of individual quantum particles. Building quantum systems from the ground up provides a wonderful opportunity to move from the simpler, few-body realm of quantum optics to the exquisite challenges of many-body quantum theory. This complements the more traditional route taken in condensed matter, where both the underlying microscopic physics and emergent behaviors must be teased from observations. In the laboratory, I study ultracold atoms in optical lattices and strongly interacting photonic quasi-particles called Rydberg polaritons with an emphasis on single-particle readout and manipulation. Exploring how quantum systems organize and respond to external stimuli will provide inspiration for the next generation of quantum devices and a deeper understanding of phenomena, from high-temperature superconductivity to topological ordering.
