Disorder-robust trivial Majorana-like states from smooth confinement in chiral superconducting nanowires
Eslam Ahmed, Jorge Cayao, Yukio Tanaka
Near-zero-energy states in Majorana nanowires can arise from topologically trivial mechanisms such as smooth spatial inhomogeneity and disorder, making zero-energy pinning alone in…
Andreev exceptional points in Josephson junctions formed by minimal Kitaev chains
Jorge Cayao, Masatoshi Sato
We consider Josephson junctions formed by two minimal Kitaev chains and investigate how the interplay between non-Hermiticity and superconducting phase difference enables the reali…
Light-induced Floquet spin-triplet Cooper pairs in unconventional magnets
Pei-Hao Fu, Sayan Mondal, Jun-Feng Liu +1
The recently predicted unconventional magnets offer a new ground for exploring the formation of nontrivial spin states due to their inherent nonrelativistic momentum-dependent spin…
All-electrically controlled spintronics in altermagnetic heterostructures
Pei-Hao Fu, Qianqian Lv, Yong Xu +3
The recent discovery of altermagnets, which exhibit spin splitting without net magnetization, opens new directions for spintronics beyond the limits of ferromagnets, antiferromagne…
Non-Hermitian multiterminal phase-biased Josephson junctions
Jorge Cayao, Masatoshi Sato
We study non-Hermitian Josephson junctions formed by multiple superconductors and discover the emergence of exceptional points entirely determined by the interplay of the distinct…
Non-Hermitian minimal Kitaev chains
Jorge Cayao, Ramón Aguado
Starting from a double quantum dot realization of a minimal Kitaev chain, we demonstrate that non-Hermicity stabilizes the so-called poor man's Majorana zero modes in a region of p…
