Fate of the one-dimensional Ising quantum critical point coupled to a gapless boson
Ori Alberton, Jonathan Ruhman, Erez Berg +1
The problem of a quantum Ising degree of freedom coupled to a gapless bosonic mode appears naturally in many one dimensional systems, yet surprisingly little is known how such a co…

Topological States in a One-Dimensional Fermi Gas with Attractive Interactions
Jonathan Ruhman, Erez Berg, Ehud Altman
We describe a novel topological superfluid state, which forms in a one-dimensional Fermi gas with Rashba-like spin-orbit coupling, a Zeeman field and intrinsic attractive interacti…

Ferromagnetic and Nematic Non-Fermi Liquids in Spin-Orbit Coupled Two-Dimensional Fermi Gases
Jonathan Ruhman, Erez Berg
We study the fate of a two-dimensional system of interacting fermions with Rashba spin-orbit coupling in the dilute limit. The interactions are strongly renormalized at low densiti…
