Plasmons in Holographic Ersatz Fermi Liquids
Eli Ismailov, Ulf Gran, Eric Nilsson
We solve an infrared effective holographic model of a non-Fermi liquid at finite temperature that satisfies Luttinger's theorem and incorporates long-range Coulomb interactions. Mo…

Nonequilibrium Relaxation and Odd-Even Effect in Finite-Temperature Electron Gases
Eric Nilsson, Ulf Gran, Johannes Hofmann
Pauli blocking in Fermi liquids imposes strong phase-space constraints on quasiparticle lifetimes, leading to a well-known quadratic-in-temperature decay rate of quasiparticle mode…

Odd-parity effect and scale-dependent viscosity in atomic quantum gases
Jeff Maki, Ulf Gran, Johannes Hofmann
Two-dimensional electron gases are predicted to possess an anomalous ''tomographic'' transport regime that is marked by an odd-even effect in the relaxation times, with odd-parity…
