The Su-Schrieffer-Heeger (SSH) model is fundamental in topological insulators and relevant
to understanding higher-order topological phases. This study explores the relationship …

The semiclassical equations of motion are widely used to describe carrier transport in
conducting materials. Nevertheless, the substantial challenge of incorporating disorder …

We provide a unified semiclassical theory for the conserved current of nonconserved
quantities, and manifest it in two physical contexts: the spin current of Bloch electrons and …

In crystalline systems, higher-order topology, characterized by topological states of
codimension greater than one, usually arises from the mismatch between Wannier centers …

The superconducting magnetoelectric effect, which is the current-induced magnetization in a
superconductor, mainly focused on spin magnetization in previous studies, but ignored the …

The integration of topological concepts into electronic energy band theory has been a
transformative development in condensed matter physics. Since then, this paradigm has …

The ferromagnetic-metal–superconductor heterostructure with spin-orbit coupling is a
promising candidate for topological superconductivity. Inspired by recent experimental …

Starting from the Keldysh theory, for a general low energy $ N $-band Hamiltonian in the
clean limit, we perform a manifestly $\smash {U (1)\times SU (N)} $ gauge invariant …

Focusing on the two-dimensional (2D) Su-Schrieffer-Heeger (SSH) model, we propose an
additive rule between the real-space topological invariant s of disclinations (related to the …

The focus of experimental efforts on topological superconductivity (TSC) has predominantly
centered around the detection of Majorana boundary modes. On the contrary, the …
