-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…
Gate-tunable nonreciprocal thermoelectric effects on the surface states of topological insulators
Phillip Mercebach, Sun-Yong Hwang, Bo Lu +3
Thermoelectric devices at the nanoscale offer promising routes for on-chip refrigeration and waste-heat recovery, yet most semiconductor-based implementations suffer from limited t…
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…
Superconducting phenomena in systems with unconventional magnets
Yuri Fukaya, Bo Lu, Keiji Yada +2
In this work we review the recent advances on superconducting phenomena in junctions formed by superconductors and unconventional magnets. Conventional magnets, such as ferromagnet…
Orientation-dependent transport in junctions formed by -wave altermagnets and -wave superconductors
Wenjun Zhao, Yuri Fukaya, Pablo Burset +3
We investigate de Gennes-Saint-James states and Josephson effect in hybrid junctions based on -wave altermagnet and -wave superconductor. Even though these states are associa…
Classification of pair symmetries in superconductors with unconventional magnetism
Kazuki Maeda, Yuri Fukaya, Keiji Yada +3
We consider unconventional magnets with proximity-induced superconductivity and investigate the emergence of superconducting correlations by carrying out a full classification of a…
