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…
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…
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…
