Fermi surface reconstruction in FeSe under high pressure

Taichi Terashima, Naoki Kikugawa, Andhika Kiswandhi +13

We report Shubnikov-de Haas (SdH) oscillation measurements on FeSe under high pressure up to = 16.1 kbar. We find a sudden change in SdH oscillations at the onset of the pressu…

Majorana bands, Berry curvature, and thermal Hall conductivity in the vortex state of a chiral p-wave superconductor

James M. Murray, Oskar Vafek

Majorana quasiparticles localized in vortex cores of a chiral p-wave superconductor hybridize with one another to form bands in a vortex lattice. We begin by solving a fully micros…
