Supercell-size scaling of moiré band flatness
Peilong Hong, Yuge Qiu, Wenjing Li +9
In moiré superlattices, the band flatness governs the degree of wave localization, which is central to harnessing emergent phenomena and designing functional meta-devices. While re…

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…

Manipulating the Relaxation Time of Boundary-Dissipative Systems through Bond Dissipation
Yi Peng, Chao Yang, Yucheng Wang
Relaxation time plays a crucial role in describing the relaxation processes of quantum systems. We study the effect of a type of bond dissipation on the relaxation time of boundary…
