Bragg-Williams order competes with superconductivity
Xu Liu, Xu Chen, Chuizhen Chen +14
Orderings in charge and spin have been extensively studied to unravel their correlation to emergent superconductivity over the past decades. Bragg-Williams order (BWO), a classical…

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…
