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…
Disorder in interacting quasi-one-dimensional systems: flat and dispersive bands
Mi-Ji Liang, Yong-Feng Yang, Chen Cheng +1
We investigate the superconductor-insulator transition (SIT) in disordered quasi-one dimensional systems using the density-matrix renormalization group method. Focusing on the case…
Observation of many-body Fock space dynamics in two dimensions
Yunyan Yao, Liang Xiang, Zexian Guo +25
Quantum many-body simulation provides a straightforward way to understand fundamental physics and connect with quantum information applications. However, suffering from exponential…
Enhanced superconductivity and various edge modes in modulated - chains
Yong-Feng Yang, Jing Chen, Chen Cheng +1
We numerically investigate the ground state of the extended - Hamiltonian with periodic local modulations in one dimension by using the density-matrix renormalization group m…
