First order character and observable signatures of topological quantum phase transitions
A. Amaricci, J. C. Budich, M. Capone +2
Topological quantum phase transitions are characterised by changes in global topological invariants. These invariants classify many body systems beyond the conventional paradigm of…
Dissipative preparation of Chern insulators
Jan Carl Budich, Peter Zoller, Sebastian Diehl
Engineered dissipation can be employed to prepare interesting quantum many body states in a non-equilibrium fashion. The basic idea is to obtain the state of interest as the unique…
Search for localized Wannier functions of topological band structures via compressed sensing
J. C. Budich, J. Eisert, E. J. Bergholtz +2
We investigate the interplay of band structure topology and localization properties of Wannier functions. To this end, we extend a recently proposed compressed sensing based paradi…
