Odd-frequency pairing due to Majorana and trivial Andreev bound states
Eslam Ahmed, Shun Tamura, Yukio Tanaka +1
Majorana and trivial Andreev bound states are predicted to appear in superconductor-semiconductor hybrid systems, but their identification is still a challenging task. Here we cons…
Josephson effect and odd-frequency pairing in superconducting junctions with unconventional magnets
Yuri Fukaya, Kazuki Maeda, Keiji Yada +3
We consider Josephson junctions formed by coupling two conventional superconductors via an unconventional magnet and investigate the formation of Andreev bound states, their impact…
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…
Emergent pair symmetries in systems with poor man's Majorana modes
Jorge Cayao
Few-site Kitaev chains are promising for realizing Majorana zero modes without topological protection but fully nonlocal, which are known as poor man's Majorana modes. While severa…
Identifying trivial and Majorana zero-energy modes using the Majorana polarization
Oladunjoye A. Awoga, Jorge Cayao
In this work we consider superconductor-semiconductor hybrids containing both trivial and Majorana zero modes and explore their signatures in the Majorana polarization. In particul…
