Enhancement of superconductivity near a nematic quantum critical point
Samuel Lederer, Yonatan Schattner, Erez Berg +1
We consider a low metallic superconductor weakly coupled to the soft fluctuations associated with proximity to a nematic quantum critical point (NQCP). We show that: 1) a BCS…
Sign Reversal of the Hall Response in a Crystalline Superconductor
Erez Berg, Sebastian D. Huber, Netanel H. Lindner
We consider the Hall conductivity due to the motion of a vortex in a lattice-model of a clean superconductor, using a combination of general arguments, unrestricted Hartree-Fock ca…
Topological Superconducting Phases of Weakly Coupled Quantum Wires
Inbar Seroussi, Erez Berg, Yuval Oreg
An array of quantum wires is a natural starting point in realizing two-dimensional topological phases. We study a system of weakly coupled quantum wires with Rashba spin-orbit coup…
