Evidence for Half-Quantized Chiral Edge Current in a C = 1/2 Parity Anomaly State
Deyi Zhuo, Bomin Zhang, Humian Zhou +5
A single massive Dirac surface band is predicted to exhibit a half-quantized Hall conductance, a hallmark of the C = 1/2 parity anomaly state in quantum field theory. Experimental…
Gate-Tunable Ambipolar Josephson Current in a Topological Insulator
Bomin Zhang, Xiaoda Liu, Junjie Qi +9
Dirac surface states in a topological insulator (TI) with proximity-induced superconductivity offer a promising platform for realizing topological superconductivity and Majorana ph…
Meissner Effect and Nonreciprocal Charge Transport in Non-Topological 1T-CrTe2/FeTe Heterostructures
Zi-Jie Yan, Ying-Ting Chan, Wei Yuan +11
Interface-induced superconductivity has recently been achieved by stacking a magnetic topological insulator layer on an antiferromagnetic FeTe layer. However, the mechanism driving…
