One-dimensional electronics with edge states in two-dimensional altermagnets
Shibo Fang, Zongmeng Yang, Jianhua Wang +5
The coupling between real-space inhomogeneities coordinates and spin (r-s) provides an alternative route to achieve efficient spin manipulation in spintronics beyond the convention…
Anyon-Induced Criticality and Dynamical Stability in Non-Hermitian Many-Body Systems
Yi Qin, Yee Sin Ang, Linhu Li +1
We show that anyonic statistics fundamentally reshapes non-Hermitian many-body physics by intrinsically breaking pseudo-Hermiticity, leading to a unique real-complex spectral trans…
Generalized Brillouin Zone Fragmentation
Haiyu Meng, Yee Sin Ang, Ching Hua Lee
The Generalized Brillouin Zone (GBZ) encodes how lattice momentum is complex-deformed due to non-Hermitian skin accumulation, and has proved essential in restoring bulk-boundary co…
Stochasticity-induced non-Hermitian skin criticality
Xiaoyu Cheng, Hui Jiang, Jun Chen +3
Typically, scaling up the size of a system does not change the shape of its energy spectrum, other than making it denser. Exceptions, however, occur in the new phenomenon of non-He…
Unconventional tunnel magnetoresistance scaling with altermagnets
Zongmeng Yang, Xingyue Yang, Jianhua Wang +7
In conventional magnetic tunnel junctions (MTJs), the tunnel magnetoresistance (TMR) typically increases with barrier thickness as electron transmission in the antiparallel configu…
Many-body critical non-Hermitian skin effect
Yi Qin, Yee Sin Ang, Ching Hua Lee +1
Criticality in non-Hermitian systems unveils unique phase transitions and scaling behaviors beyond Hermitian paradigms, offering new insights into the interplay between gain/loss,…
