Nonlocal Josephson diode effect in minimal Kitaev chains
Jorge Cayao, Masatoshi Sato
We study the emergence of the nonlocal Josephson effect in a system composed of three laterally coupled minimal Kitaev chains and exploit it to realize the nonlocal Josephson diode…
Odd-frequency Pairing in Josephson Junctions Coupled by Magnetic Textures
Ignacio Sardinero, Jorge Cayao, Rubén Seoane Souto +1
Josephson junctions coupled through magnetic textures provide a controllable platform for odd-frequency superconductivity and Majorana physics. Within a tight-binding Green functio…
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…
Non-Hermitian Josephson junctions with four Majorana zero modes
Jorge Cayao, Masatoshi Sato
Josephson junctions formed by finite-length topological superconductors host four Majorana zero modes when the phase difference between the superconductors is and their lengt…
Engineering subgap states in superconductors by the symmetry of altermagnetism
Bo Lu, Phillip Mercebach, Pablo Burset +4
Combining superconducting and magnetic materials is a promising path to generate exotic interface subgap states. In this regard, altermagnetism is particularly interesting because…
The Josephson effect in Fibonacci superconductors
Ignacio Sardinero, Jorge Cayao, Keiji Yada +2
We theoretically investigate the Josephson effect between two proximized Fibonacci quasicrystals. A quasiperiodic modulation of the chemical potential on a superconducting substrat…
