Correlation dynamics during a slow interaction quench in a one-dimensional Bose gas
Jean-Sebastien Bernier, Roberta Citro, Corinna Kollath +1
We investigate the response of a one-dimensional Bose gas to a slow increase of its interaction strength. We focus on the rich dynamics of equal-time single-particle correlations t…
Kondo screening by the surface modes of a strong topological insulator
Edmond Orignac, Sébastien Burdin
We consider a magnetic impurity deposited on the surface of a strong topological insulator and interacting with the surface modes by a Kondo exchange interaction. Taking into accou…
Effect of disorder on 2D topological merging transition from a Dirac semi-metal to a normal insulator
David Carpentier, Andrei A. Fedorenko, Edmond Orignac
We study the influence of disorder on the topological transition from a two-dimensional Dirac semi-metal to an insulating state. This transition is described as a continuous mergin…
Bosonization and entanglement spectrum for one-dimensional polar bosons on disordered lattices
X. Deng, R. Citro, E. Orignac +2
The extended Bose-Hubbard model subjected to a disordered potential is predicted to display a rich phase diagram. In the case of uniform random disorder one finds two insulating qu…
