Characterization of Lifshitz transitions in topological nodal line semimetals
Hui Jiang, Linhu Li, Jiangbin Gong +1
We introduce a two-band model of three-dimensional nodal line semimetals, the Fermi surface of which at half-filling may form various one-dimensional configurations of different to…
Dynamical topological invariant after a quantum quench
Chao Yang, Linhu Li, Shu Chen
We show how to define a dynamical topological invariant for general one-dimensional topological systems after a quantum quench. Focusing on two-band topological insulators, we demo…
Engineering topological phases with a three-dimensional nodal-loop semimetal
Linhu Li, Han Hoe Yap, Miguel A. N. Araújo +1
A three-dimensional (3D) nodal-loop semimetal phase is exploited to engineer a number of intriguing phases featuring different peculiar topological surface states. In particular, b…
Transition from nodal loop to nodal chain phase in a periodically modulated optical lattice
Chuanhao Yin, Linhu Li, Shu Chen
We propose to study the transition from a nodal loop to nodal chain phase in a tunable two-dimensional -flux lattice with periodical modulation potential. The Hamiltonian descri…
-flux loop semimetals
Linhu Li, Stefano Chesi, Chuanhao Yin +1
We introduce a model of -flux loop semimetals which holds nodal loops described by a winding number . By adding some extra terms, this model can be transformed into a rece…
Chiral topological insulating phases from three-dimensional nodal loop semimetals
Linhu Li, Chuanhao Yin, Shu Chen +1
We identify a topological Z index for three dimensional chiral insulators with P*T symmetry where two Hamiltonian terms define a nodal loop. Such systems may belong in the AIII or…
