Intertwining topological order and discrete broken symmetries in the hole-doped cuprates via quantum fluctuating antiferromagnetismThe enigmatic pseudogap metal phase of the hole-doped cuprate superconductors has two seemingly unrelated characteristics: (i) a gap in the electronic spectrum along the axes of the square lattice Brillouin zone, and (ii) the presence of discrete broken symmetries (like rotation, inversion or time-reversal). In a normal metal with full translational symmetry, a gap in the electron spectrum in the anti-nodal region cannot be explained by such broken symmetries. We propose a resolution to this puzzle by intertwining topological order with broken symmetries in the pseudogap metal. We show that the required flavors of topological order, corresponding to precisely the broken symmetries observed in the cuprates, arise naturally in a SU(2) gauge theory of quantum fluctuations of magnetically ordered phases that lie proximate to the Néel phase. We explore how alternative descriptions of fluctuating Néel antiferromagnets, in terms of the semiclassical O(3) non-linear σ model, and the CP1 model, also naturally lead to the same phases. If time permits, we will also discuss comparisons between the gauge theory and recent numerical (DMFT and QMC) results on the two-dimensional Hubbard model.

A View into the "Century of Biology" and AgilentTechnology leadership based on a culture of innovation, contribution and sustained R&D investment has been at the core of Agilent's success through decades of market and technology waves. Today, biology is the field where science and understanding are most rapidly changing. This talk will highlight key megatrends in this 'century of biology', Agilent's transition from being a predominantly electronics and semiconductor company into one fully-focused on the life science and diagnostics industries, and some of the technology contributions underway at Agilent that will underlie tomorrow's breakthroughs.

Near Term Applications of Quantum Simulation and Quantum Computing DevicesThe exact solution of the Schrödinger equation for atoms, molecules and extended systems continues to be a “Holy Grail” problem for the field of atomic and molecular physics since inception. Recently, breakthroughs have been made in the development of hardware-efficient quantum optimizers and coherent Ising machines capable of simulating hundreds of interacting spins through an Ising-type Hamiltonian. One of the most vital questions associated with these new devices is: “Can these machines be used to perform electronic structure calculations?” In this talk I will discuss the possibility of mapping the electronic structure Hamiltonian to an Ising type Hamiltonian and present the simulation results of the transformed Ising Hamiltonian for small molecules such as H2, He2, HeH+, LiH and H2O. Future directions for scaling up the simulations to larger systems will be also discussed.For further information please contact Brenda Thomas at 773-702-7156 or by email at firstname.lastname@example.org.

Looking for Relativistic Hydrodynamics in Solid State PhysicsInteractions between the Dirac fermions in graphene can lead to
new collective behavior described by hydrodynamics. By listening
to the Johnson noise of the electrons, we are able to probe
simultaneously the thermal and electrical transport of the Dirac fluid
and observe how it departs from Fermi liquid physics. At high
temperature near the neutrality point, we find a strong
enhancement of the thermal conductivity and breakdown of
Wiedemann-Franz law in graphene. This is attributed to the non-
degenerate electrons and holes forming a strongly coupled Dirac
fluid. We shall take an outlook on the hydrodynamic physics
experiments in solid state systems. Ref: Science 351, 1058 (2016)

Quantum dynamics with Statistical Effects and Statistical Models of Quantum EffectsThe capability of electronic structure to calculate the wavefunctions, and even dynamics of large systems has improved dramatically. This has put electronic structure into an uncomfortable regime where statistical effects become as important as the correlation problem. I will discuss our efforts to describe mixed-state electronic dynamics with density matrix equations of motion, and the applications of those theories to ultrafast experiments. Realtime mean field theories such as RT-TDDFT and RT-TDHF dominate applications because of the speed required to access picosecond timescales. Yet TDHF and TDDFT are not accurate enough to properly model resonant driving, which is only one ingredient in ultrafast spectroscopy. In this talk I discuss a simple density-matrix equation of motion implemented as an approximation to RT-TDDFT, which excites properly on resonance. Based on this foundation I compare the non-equilibrium steady states of the correct DFT and a Markovian bath model, with essentially exact results coming from HEOM showing that TDDFT can be used to study driven ultrafast dynamics. I then discuss self-consistency in correlated corrections to TDDFT which have low cost and can be applied to large systems. Statistical sampling of molecular geometries has become an equally important issue, although empirical density functionals, which are the most practical tools for exploring geometries, make an ambiguous mixture of quantum physics and statistical modeling. I will demonstrate purely statistical models of molecular structure, and show that in the near future it is likely that purely empirical models of the PES will have several appealing advantages over empirical hybrids. of quantum mechanical models with statistics.For further information please contact Brenda Thomas at 773-702-7156 or by email at email@example.com.

Enrico Fermi: The Pope of PhysicsEnrico Fermi has been called the last scientist who knew all of physics, having attained the heights of the profession as a theorist and experimentalist. Unique in numerous ways, this 20th century physicist was entirely self-taught; the breadth and depth of his research remain unparalleled. Fermi’s 1938 Nobel Prize was picked up en route in his flight from fascist Italy with his Jewish wife and children to a new life in America. In 1942 he became the lead scientist in the University of Chicago experiment that produced the first self-sustaining nuclear chain reaction, a key precursor to building the atomic bomb. His role in the success of the Manhattan Project was critical.
This lecture combines Fermi’s personal life with his scientific contributions and illustrates how he was shaped by history and how he, in turn, shaped history. Legendarily apolitical, Fermi was reluctantly involved in American political decision making during the war and afterwards. The many challenges he faced, including the tensions between politics and science, are still relevant today.
