Momentum distribution and tunneling density of states of one-dimensional Fermonic SU(N) Hubbard model
Shuang Liang, Deping Zhang, Wei Chen
We study the one-dimensional Fermionic Hubbard model with SU(N) spin symmetry in the incommensurate filling case. The basic properties of Green's function, momentum distribution an…
Universal quantum criticality in static and Floquet-Majorana chains
Paolo Molignini, Wei Chen, R. Chitra
The topological phase transitions in static and periodically driven Kitaev chains are investigated by means of a renormalization group (RG) approach. These transitions, across whic…
Intermediate gapless phase and topological phase transition of Kitaev model in a uniform magnetic field
Shuang Liang, Minghong Jiang, Wei Chen +2
We study the Kitaev spin liquid (KSL) in a [001] magnetic field employing the mean field theory (MFT/MF) in the Majorana fermion representation. The MF Hamiltonian of the system ha…
Renormalization group approach to symmetry protected topological phases
Evert P. L. van Nieuwenburg, Andreas P. Schnyder, Wei Chen
A defining feature of a symmetry protected topological phase (SPT) in one-dimension is the degeneracy of the Schmidt values for any given bipartition. For the system to go through…
Weakly Interacting Topological Insulators: Quantum Criticality and Renormalization Group Approach
Wei Chen
For D-dimensional weakly interacting topological insulators in certain symmetry classes, the topological invariant can be calculated from a D- or (D+1)-dimensional integration over…
Proposal for detecting nodal-line semimetal surface-states with resonant spin-flipped reflection
Wei Chen, Kun Luo, Lin Li +1
Topological nodal-line semimetals are predicted to exhibit unique drumhead-like surface states (DSS). Yet, a direct detection of such states remains a challenge. Here, we propose s…
