The Hierarchy of Excitation Lifetimes in Two-Dimensional Fermi Gases
Patrick J Ledwith, Haoyu Guo, Leonid Levitov
Momentum-conserving quasiparticle collisions in two-dimensional Fermi gases give rise to a large family of exceptionally long-lived excitation modes. The lifetimes of these modes e…
Thermal Uhlmann Chern number from the Uhlmann connection for extracting topological properties of mixed states
Yan He, Hao Guo, Chih-Chun Chien
The Berry phase is a geometric phase of a pure state when the system is adiabatically transported along a loop in its parameter space. The concept of geometric phase has been gener…
Tomographic Dynamics and Scale-Dependent Viscosity in Two-Dimensional Electron Systems
Patrick J Ledwith, Haoyu Guo, Andrey V Shytov +1
Fermi gases in two dimensions display a surprising collective behavior originating from the head-on carrier collisions. The head-on processes dominate angular relaxation at not-too…
Angular Superdiffusion and Directional Memory in Two-Dimensional Electron Fluids
Patrick Ledwith, Haoyu Guo, Leonid Levitov
We demonstrate that 2D Fermi liquids can support peculiar excitations that are not subject to Landau's dissipation. The long-lived excitations relax through correlated angula…
Stokes Paradox, Back Reflections and Interaction-Enhanced Conduction
Haoyu Guo, Ekin Ilseven, Gregory Falkovich +1
Interactions in electron systems can lead to viscous flows in which correlations allow electrons to avoid disorder scattering, reducing momentum loss and dissipation. We illustrate…
Higher-Than-Ballistic Conduction of Viscous Electron Flows
Haoyu Guo, Ekin Ilseven, Gregory Falkovich +1
Strongly interacting electrons can move in a neatly coordinated way, reminiscent of the movement of viscous fluids. Here we show that in viscous flows interactions facilitate trans…
