Collective excitations and stability of a non-Fermi liquid state near a quantum-critical point of a metal
Yasha Gindikin, Dmitrii L. Maslov, Andrey V. Chubukov
We examine the spectral properties of collective excitations with finite angular momentum for a system of interacting fermions near a Pomeranchuk quantum critical point, both i…

Electron Interactions in Rashba Materials
Yasha Gindikin, Alex Kamenev
We present a bunch of novel phenomena stemming from the pair spin-orbit interaction (PSOI), which does not rely on structure inversion asymmetry but instead arises from Coulomb fie…

Quantum criticality and optical conductivity in a two-valley system
Yasha Gindikin, Songci Li, Alex Levchenko +3
We demonstrate that the optical conductivity of a Fermi liquid (FL) in the absence of umklapp scattering is dramatically affected by the topology of the Fermi surface (FS). Specifi…
