Binding energy, which quantifies pair formation, is a key factor in the emergence of superconductivity. Here, we show that even when multiple spins are complexly coupled, hole-doped systems, which can be mapped onto the universal hardcore boson model in the strong-binding-energy limit, exhibit promi…

The

G W

method delivers substantially improved accuracy in electronic band structure calculations over conventional Kohn-Sham density functional theory (KS-DFT) by explicitly incorporating the electron self-energy effect beyond mean-field approximations. In this work, we present an efficient NAO-PP-b…

A detailed theoretical understanding and experimental characterization of magnetic nanoelectromechanical devices is crucial for future technological applications. Here, we investigate the transport characteristics of a nanoelectromechanical spin-valve device, which is coupled to two magnetically pol…

Nonequilibrium topological response under charge dephasing

Shuangyuan Lu, Lucas Q. Silveira, and Yizhi You — 2026-09-10T10:00:00+00:00

Author(s): Shuangyuan Lu, Lucas Q. Silveira, and Yizhi You
We explore nonequilibrium topological responses of symmetry-protected topological (SPT) states in open quantum systems subject to decoherence. For SPT wavefunctions protected by a product symmetry G × S, where G defects are decorated with S charge, we show that local dephasing of the S charge densit…
