Topological Origin of Non-Hermitian Skin Effects
Nobuyuki Okuma, Kohei Kawabata, Ken Shiozaki +1
A unique feature of non-Hermitian systems is the skin effect, which is the extreme sensitivity to the boundary conditions. Here, we reveal that the skin effect originates from intr…

Topological Phase Transition driven by Infinitesimal Instability: Majorana Fermions in Non-Hermitian Spintronics
Nobuyuki Okuma, Masatoshi Sato
Quantum phase transitions are intriguing and fundamental cooperative phenomena in physics. Analyzing a superconducting nanowire with spin-dependent non-Hermitian hopping, we discov…
