Mott insulating states and quantum phase transitions of correlated SU(2N) Dirac fermions

Zhichao Zhou, Da Wang, Zi Yang Meng +2

The interplay between charge and spin degrees of freedom in strongly correlated fermionic systems, in particular of Dirac fermions, is a long-standing problem in condensed matter p…

Topological invariants for interacting topological insulators: II. Breakdown of the Green's function formalism

Yuan-Yao He, Han-Qing Wu, Zi Yang Meng +1

Topological phase transitions in free fermion systems can be characterized by closing of single-particle gap and change in topological invariants. However, in the presence of elect…

Topological invariants for interacting topological insulators: I. Efficient numerical evaluation scheme and implementations

Yuan-Yao He, Han-Qing Wu, Zi Yang Meng +1

The aim of this series of two papers is to discuss topological invariants for interacting topological insulators (TIs). In the first paper (I), we provide a paradigm of efficient n…

Bona fide interaction-driven topological phase transition in correlated SPT states

Yuan-Yao He, Han-Qing Wu, Yi-Zhuang You +3

It is expected that the interplay between non-trivial band topology and strong electron correlation will lead to very rich physics. Thus a controlled study of the competition betwe…

Multiplicative logarithmic corrections to quantum criticality in three-dimensional dimerized antiferromagnets

Yan Qi Qin, Bruce Normand, Anders W. Sandvik +1

We investigate the quantum phase transition in an dimerized Heisenberg antiferromagnet in three spatial dimensions. By performing large-scale quantum Monte Carlo simulati…

Quantum Monte Carlo study of strange correlator in interacting topological insulators

Han-Qing Wu, Yuan-Yao He, Yi-Zhuang You +3

Distinguishing the nontrivial symmetry-protected topological (SPT) phase from the trivial insulator phase in the presence of electron-electron interaction is an urgent question to…
