Switchable half-quantum flux states in a ring of the kagome superconductor CsVSb
Shuo Wang, Ilaria Maccari, Xilin Feng +14
Magnetic flux quantization in units of is a defining feature of superconductivity, rooted in the charge-2e nature of Cooper pairs. In a ring geometry, the flux quanti…

Josephson Diode Effect for a Kitaev Ladder System
Cheng-Rong Xie, Hiroki Tsuchiura, Manfred Sigrist
We study the Josephson diode effect realized purely by geometry in a Kitaev-ladder Josephson junction composed of two parallel spinless -wave chains coupled by an interleg hoppi…

General Strategy for Large Nernst Coefficient
Junya Endo, Hiroyasu Matsuura, Manfred Sigrist +1
We propose a general strategy for enhancing the anomalous Nernst coefficient based on the Sommerfeld-Bethe relation. This approach provides a systematic framework for understanding…
