Emergent topological properties in spatially modulated sub-wavelength barrier lattices
Giedrius Žlabys, Wen-Bin He, Domantas Burba +3
We investigate topological phenomena in a spatially modulated Dirac- lattice, where the scattering potential varies periodically in space. Changing the potential modulation freq…

Quench dynamics in topologically non-trivial quantum many-body systems
Sarika Sasidharan Nair, Giedrius Žlabys, Wen-Bin He +2
We investigate the nonequilibrium dynamics of a groundstate fermionic many body gas subjected to a quench between parameter regimes of a topologically nontrivial Hamiltonian. By fo…

The Lieb excitations and topological flat mode of spectral function of Tonks-Girardeau gas in Kronig-Penney potential
Wen-Bin He, Giedrius Žlabys, Hoshu Hiyane +2
Lieb excitations are fundamental to the understanding of the low energy behaviour of many-body quantum gases. Here we study the spectral function of a Tonks-Girardeau gas in a fini…
