Preparing Atomic Topological Quantum Matter by Adiabatic Nonunitary Dynamics
S. Barbarino, J. Yu, P. Zoller +1
Motivated by the outstanding challenge of realizing low-temperature states of quantum matter in synthetic materials, we propose and study an experimentally feasible protocol for pr…
Helical Floquet Channels in 1D Lattices
Jan Carl Budich, Ying Hu, Peter Zoller
We show how dispersionless channels exhibiting perfect spin-momentum locking can arise in a 1D lattice model. While such spectra are forbidden by fermion doubling in static 1D syst…
Topological Quantum Matter with Ultracold Gases in Optical Lattices
N. Goldman, J. C. Budich, P. Zoller
Since the discovery of topological insulators, many topological phases have been predicted and realized in a range of different systems, providing both fascinating physics and exci…
Topology of density matrices
Jan Carl Budich, Sebastian Diehl
We investigate topological properties of density matrices motivated by the question to what extent phenomena like topological insulators and superconductors can be generalized to m…
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…
