Bogoliubov flat bands in twisted layered materials
Keiji Yada, Yuri Fukaya, Yukio Tanaka
Flat bands have attracted considerable interest in condensed matter physics because they provide a fertile platform for realizing strongly correlated and topological quantum phases…
-wave superconductivity and Josephson current in -wave unconventional magnet/-wave superconductor hybrid systems
Yuri Fukaya, Keiji Yada, Yukio Tanaka
We study the surface density of states in -wave unconventional magnet-spin-singlet -wave superconductor hybrid systems (-wave unconventional magnetic superconductors). Owi…
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…
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…
Tunneling conductance in superconducting junctions with -wave unconventional magnets breaking time-reversal symmetry
Yuri Fukaya, Keiji Yada, Yukio Tanaka
A new type of magnet called -wave unconventional magnet is proposed, stimulated by the discovery of altermagnet. We study the tunneling conductance of -wave unconventional ma…
