Plasmon-driven exciton formation in a non-equilibrium Fermi liquid
Rishi Acharya, Eli Gerber, Nina Bielinski +13
Collective modes in Fermi liquids are usually regarded as dissipation channels that relax electronic excitations through Landau damping. Whether such modes can instead mediate the…
Universality of the Mott Transition
Jinchao Zhao, Peizhi Mai, Gaurav Tenkila +1
We demonstrate that the Mott transition exhibits universal scaling as a consequence of the breaking of a symmetry in momentum space. A direct consequence of this dis…
Twisting the Hubbard model into the Momentum-Mixing Hatsugai-Kohmoto Model
Peizhi Mai, Jinchao Zhao, Gaurav Tenkila +4
The Hubbard model is a standard theoretical tool for studying materials with strong electron-electron interactions, such as the cuprate superconductors. Unfortunately, interaction-…
Boundary Criticality in the 2d Random Quantum Ising Model
Gaurav Tenkila, Romain Vasseur, Andrew C. Potter
The edge of a quantum critical system can exhibit multiple distinct types of boundary criticality. We use a numerical real-space renormalization group (RSRG) to study the boundary…
