Parity-Anomalous Hall Response of Chiral Lifshitz Fermions
Yanmiao Han, Rundong Zhao, Yu-Hao Wan
The parity anomaly of a single massless Dirac fermion is manifested as a half-quantized Hall response once the required parity-breaking regularization is supplied. We study the cor…
Anti-higher-order Weyl semimetal
Cheng-Ming Miao, Yu-Hao Wan, Qing-Feng Sun
Higher-order topology extends the bulk-boundary correspondence by enabling corner or hinge localized states. Here we identify an anti-higher-order Weyl semimetal, a three dimension…
Anti-higher-order topological insulators
Cheng-Ming Miao, Yu-Hao Wan, Ying-Tao Zhang +1
Duality is a fundamental concept in physics that connects complementary opposites like particles and holes. Similarly, while topological states in topological insulators localize a…
Quantum anomalous Hall effect in chiral semimetals
Peng-Yi Liu, Yu-Hao Wan, Qing-Feng Sun
The quantum anomalous Hall (QAH) effect is conventionally understood to exist only in Chern insulators, while a recent study has shown that ferromagnetic metals can also host the Q…
Robust quantized thermal conductance of Majorana floating edge bands in d-wave superconductors
Yanmiao Han, Yu-Hao Wan, Zhaoqin Cao +2
We propose and characterize a new class of Majorana boundary states, i.e., floating Majorana edge bands (FMEBs), which emerge in two-dimensional (2D) superconductors that break tim…
The emergence of net chirality in two-dimensional Dirac fermions system with altermagnetic mass
Peng-Yi Liu, Yu-Hao Wan, Qing-Feng Sun
In two-dimensional lattice systems, massless Dirac fermions undergo doubling, leading to the cancellation of net chirality. We demonstrate that the recently discovered altermagneti…
