Robust Spin Logic Enabled by Generalized Symmetry in -Wave Magnets
Hao-Kun Ke, Gong Zhao, Siqing Li +2
Unconventional magnets combine the vanishing stray fields of antiferromagnets with the strong spin-splitting of ferromagnets, offering a unique material platform for spintronics. H…
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…
Interlayer Exchange Coupling-Induced Critical-Metal-to-Insulator Phase Transition in Quantum Anomalous Hall Insulators
Ruoxi Zhang, Yi-Fan Zhao, Ling-Jie Zhou +6
Interlayer exchange coupling (IEC) between two magnetic layers sandwiched by a nonmagnetic spacer layer plays a critical role in shaping the magnetic properties of such heterostruc…
