Pseudo-Riemannian metric: a new perspective on the quantum realm
Miaomiao Wei, Longjun Xiang, Fuming Xu +2
As a fundamental concept in condensed matter physics, quantum geometry within the Riemannian metric elucidates various exotic phenomena, including the Hall effects driven by Berry…
Quantum intrinsic -odd spin Hall effect in altermagnets
Miaomiao Wei, Longjun Xiang, Fuming Xu +2
Drude weight, historically associated with the longitudinal Drude conductivity, can be generalized to describe the transverse or Hall component of the extrinsic conductivity tensor…
Unified framework of the microscopic Landau-Lifshitz-Gilbert equation and its application to Skyrmion dynamics
Fuming Xu, Gaoyang Li, Jian Chen +4
The Landau-Lifshitz-Gilbert (LLG) equation is widely used to describe magnetization dynamics. We develop a unified framework of the microscopic LLG equation based on the nonequilib…
Quantum Fluctuation of the Quantum Geometric Tensor and its Manifestation as Intrinsic Hall Signatures in Time-Reversal Invariant Systems
Miaomiao Wei, Luyang Wang, Bin Wang +4
In time-reversal invariant systems, all charge Hall effects predicted so far are extrinsic effects due to the dependence on the relaxation time. We explore intrinsic Hall signature…
Effective Long-Range Pairing and Hopping in Topological Nanowires Weakly Coupled to -Wave Superconductors
H. Q. Wang, L. B. Shao, Y. X. Zhao +3
In this Letter, we first formulate an effective theory, which generally captures long-range proximity effects of a surface system weakly coupled to an s-wave superconductor. The lo…
Quantum inductance and negative electrochemical capacitance at finite frequency
J. Wang, B. G. Wang, H. Guo
We report on theoretical investigations of frequency dependent quantum capacitance. It is found that at finite frequency a quantum capacitor can be characterized by a classical RLC…
