Dissipation-induced Half Quantized Conductance in One-dimensional Topological Systems
Bozhen Zhou, Pan Zhang, Yucheng Wang +1
Quantized conductance from topologically protected edge states is a hallmark of two-dimensional topological phases. In contrast, edge states in one-dimensional (1D) topological sys…

Extended Landauer-Büttiker Formula for Current through Open Quantum Systems with Gain or Loss
Chao Yang, Yucheng Wang
The Landauer-Büttiker formula, which characterizes the current flowing through a finite region connected to leads, has significantly advanced our understanding of transport. We ext…

Dissipation-assisted preparation of topological boundary states
Yi Peng, Chao Yang, Haiping Hu +1
Robust states emerging at the boundaries of a system are an important hallmark of topological matter. Here, using the Su-Schrieffer-Heeger model and the Kitaev chain as examples, w…
