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…
Nonlocal Majorana polarization in non-Hermitian topological superconductors
Arjun S. Kumar, Jorge Cayao, Oladunjoye A. Awoga
The nonlocal Majorana polarization, defined as the product of the expectation values of the particle-hole operator at opposite halves of the system, has been shown to be a reliable…
Breathing mode inducing dynamical pairing in Kagome materials
Debmalya Chakraborty, Anushree Datta, Jorge Cayao
The breathing mode in Kagome materials is a structural modulation that breaks inversion symmetry and has been shown to be a crucial source for intriguing phases in the normal state…
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…
Crossed surface flat bands in three-dimensional superconducting altermagnets
Yuri Fukaya, Bo Lu, Keiji Yada +2
Superconducting altermagnets have proven to be a promising ground for emergent phenomena, but their study has involved two-dimensional systems. In this work, we investigate three-d…
Spin-polarized Josephson current induced by inhomogeneous altermagnetic interlayers
Wenjun Zhao, Yuri Fukaya, Pablo Burset +3
The pursuit of dissipationless spin supercurrents is a central theme in superconducting spintronics. We propose a field-free Josephson junction using an inhomogeneous altermagnetic…
