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…

Quantum Anomalous Hall Effect in Ferromagnetic Metals
Yu-Hao Wan, Peng-Yi Liu, Qing-Feng Sun
The quantum anomalous Hall (QAH) effect holds fundamental importance in topological physics and technological promise for electronics. It is generally believed that the QAH effect…
