Simulatable models of Quantum Criticality in Heavy Fermion Systems - Tarun Grover
Tue, Dec 6, 2022, 12:00 pm1:00 pm

Abstract: The fermion sign problem tends to stymie exploration of
highly entangled phases of fermions, such as those relevant for heavy
fermion quantum criticality. In this talk, I will present recent
progress in simulating Fermi and non-Fermi liquids in the context of
Kondo lattice systems. One of the new ideas is…

Condensed Matter Seminar - Engineering topological phases with a superlattice potential
Tue, Nov 29, 2022, 12:00 pm1:30 pm

Abstract: We propose an externally imposed superlattice potential as a platform for manipulating topological phases, which has both advantages and disadvantages compared to a moire superlattice. In the first example, we apply the superlattice potential to the 2D surface of a 3D topological insulator. The superlattice potential creates tunable…

PostPandemic Tool for Quantum Materials and vice-versa
Tue, Nov 15, 2022, 12:30 pm1:30 pm

Raman scattering, invented at the end of the last pandemic, can provide a wealth of information on the fractional, magnetic, lattice and charge excitations at the heart of quantum materials and devices. I will first discuss how Raman provides direct evidence for coupled phonon-electron fluids in topological semimetals, helping to explain their…

Special Condensed Matter Seminar: Thermodynamic sensing of correlated insulators and their excitations in moiré materials
Fri, Sep 30, 2022, 12:30 pm1:30 pm

Abstract: Twisted van der Waals materials provide a new venue to explore flat electronic bands and the interaction-driven states they host. While many such phases have been reported, little is known about their excitations or how they depend on externally applied fields. In this talk, I will present two examples where…
