Intrinsic Nonreciprocity in Electron-Phonon Interaction Driven Thermoelectric Diodes
Hao-Kun Ke, Lie-Run Tian, Pei-Hao Fu +3
We study an electron-phonon interaction driven thermoelectric diode. The nonreciprocity in this diode arises from the asymmetry between the probabilities of phonon emission and abs…
Time reversal reserved spin valve and spin transistor based on unconventional -wave magnets
Ze-Yong Yuan, Jun-Feng Liu, Pei-Hao Fu +1
The anisotropic spin splitting in unconventional magnets opens new opportunities for realizing spintronic functionalities without relying on net magnetization or relativistic spin-…
Perfect spin nonreciprocity in gated superconducting altermagnetic heterostructures
Pei-Hao Fu, Jun-Feng Liu, Luca Chirolli +1
We consider a superconducting altermagnet heterostructure and demonstrate that the interplay between altermagnetism and a selective filter of transverse momentum channels enables p…
Intrinsic Spin Filter Effect in a -wave altermagnet KVSeO with Open Fermi Surface
Bin Liu, Pei-Hao Fu, Yu-Xuan Sun +5
Altermagnets offer a unique pathway to functional spintronics by combining vanishing magnetization with large spin splitting. Here, we demonstrate that the canonical d-wave alterma…
Light-induced Floquet spin-triplet Cooper pairs in unconventional magnets
Pei-Hao Fu, Sayan Mondal, Jun-Feng Liu +1
The recently predicted unconventional magnets offer a new ground for exploring the formation of nontrivial spin states due to their inherent nonrelativistic momentum-dependent spin…
Efficient two-color Floquet control of the RKKY interaction in altermagnets
Mohsen Yarmohammadi, Pei-Hao Fu, James K. Freericks
Magnetic impurities in real materials can mask the intrinsic spin-dependent properties of hosts. They interact indirectly through the Ruderman-Kittel-Kasuya-Yosida (RKKY) mechanism…
