Abstract
It has recently been predicted that two-dimensional electron gases possess an anomalous transport regime outside of the traditional collisionless and hydrodynamic limit. This anomalous regime is marked by the appearance of an odd-even effect where deformations of the Fermi surface with odd-parity become long-lived in comparison to even-parity ones. The presence of these odd-parity modes is notable in transverse probes of the fluid like the shear viscosity. Although this effect was first predicted in the context of electron hydrodynamics, this effect is general to fermionic systems in two dimensions. An important question is then whether ultracold quantum gases can be used to study the odd-even effect? In this talk I show how current experiments in harmonically trapped two-dimensional Fermi gases can exhibit the odd-even effect and I explain how it can be detected by examining the damping of collective oscillations.
Anyone interested is welcome to attend.
