Two-dimensional quadratic double Weyl semimetal
Xinlei Zhao, Fengjie Ma, Peng-Jie Guo +1
Unconventional Weyl semimetals have attracted intensive research interest in condensed matter physics and materials science, but they are very rare in two dimensions. In this work,…
Observation of surface superconductivity in a three-dimensional Dirac material
Qi Liu, Peng-Jie Guo, Xiao-Yu Yue +10
Superconductivity becomes more interesting when it encounters dimensional constraint or topology, because it is of importance for exploring exotic quantum phenomena or developing s…
Quantum Anomalous Hall Effect in Antiferromagnetism
Peng-Jie Guo, Zheng-Xin Liu, Zhong-Yi Lu
So far, experimentally realized quantum anomalous Hall (QAH) insulators all exhibit ferromagnetic order and the QAH effect only occurs at very low temperatures. On the other hand,…
Anomalous Faraday effect in a -symmetric dielectric slab
Vladimir Gasparian, Peng Guo, Esther Jódar
In this letter we discuss a phase transition-like anomalous behavior of Faraday rotation angles in a simple parity-time () symmetric model with two complex…
