Dramatic advances in tabletop generation of THz pulses with high field levels have enabled nonlinear THz spectroscopy and THz control over molecules and materials. The most widely used approach for generation of strong fields in the 0.2-2 THz range involves excitation of phonon-polaritons in ferroelectric host crystals, and a THz polaritonics platform has been developed that includes capabilities for THz field control and visualization as well as direct and strong coupling to collective spin waves (magnons). Recent developments in THz generation, nonlinear spectroscopy, and control over...

I will describe a method "DMT" for approximating density operators of 1D systems as low bond dimension matrix product operators that, when combined with a standard framework for time evolution (TEBD), makes possible simulation of the dynamics of strongly thermalizing systems to arbitrary times. The method performs well for both near-equilibrium initial states (Gibbs states with spatially varying temperatures) and far-from-equilibrium initial states, including quenches across phase transitions and pure states. I will also discuss ongoing work applying the method to the diffusive-...

The presentation will give an overview of the Innovation Institute, with an emphasis on how the Institute supports faculty and students with their entrepreneurial pursuits.

Pennsylvania Chapter of American Vacuum Society will be hosting two days-long “Vacuum Fundamentals, Techniques, and Deposition Technology” workshop at the University Club of the University of Pittsburgh Pittsburgh, PA on October 16-17, 2017.

NIST will be hosting a day-long “Building the Foundations for Quantum Industry” discussion at THEIR main campus in Gaithersburg, MD on October 5th.

DARPA will present its Young Faculty Award webinar tomorrow afternoon (2PM-5PM- Tuesday August 29); the Office of Research will host a viewing of the event. Interested early career faculty may contact Ryan Champagne or register online- there is space available. DARPA’s webinars provide an introduction to the agency, describe program requirements, and provide an opportunity to ask questions to the program manager.

Quantum materials research aims to uncover exotic physics and identify avenues towards next generation technologies. In particular, van der Waals materials and topological systems present a rich landscape for engineering novel electronic properties. In this talk, I will present our experiments investigating the physics of ultra-thin WTe₂, in which we find three phases to add to the 2D materials library. (1) Trilayer WTe₂ exhibits a finite-density semimetallic phase with strongly gate-tunable magnetoresistance. (2) Un-doped monolayer WTe₂ exhibits behaviors...
