Interaction-Split Edge Spectral Flow in an Integer Hubbard Thouless Pump
Yong-Feng Yang, Zhao-Rui Tian, Chen Cheng +1
We show that local Hubbard correlations can split the open-boundary spectral flow of an otherwise integer Thouless pump. Using density-matrix renormalization group calculations for…

On the criticality of the configuration-space statistical geometry
Yu-Jing Liu, Wen-Yu Su, Yong-Feng Yang +2
While phases and phase transitions are conventionally described by local order parameters in real space, we present a unified framework characterizing the phase transition through…
