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…
Voltage-tunable Majorana bound states in time-reversal symmetric bilayer quantum spin Hall hybrid systems
F. Schulz, J. C. Budich, E. G. Novik +2
We investigate hybrid structures based on a bilayer quantum spin Hall system in proximity to an s-wave superconductor as a platform to mimic time-reversal symmetric topological sup…
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…
Dynamical Buildup of a Quantized Hall Response from Non-Topological States
Ying Hu, Peter Zoller, Jan Carl Budich
We consider a two-dimensional system initialized in a topologically trivial state before its Hamiltonian is ramped through a phase transition into a Chern insulator regime. This sc…
Synthetic Helical Liquids with Ultracold Atoms in Optical Lattices
J. C. Budich, C. Laflamme, F. Tschirsich +2
We discuss a platform for the synthetic realization of key physical properties of helical Tomonaga Luttinger liquids (HTLLs) with ultracold fermionic atoms in one-dimensional optic…
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…
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…
Topological insulators with arbitrarily tunable entanglement
J. C. Budich, J. Eisert, E. J. Bergholtz
We elucidate how Chern and topological insulators fulfill an area law for the entanglement entropy. By explicit construction of a family of lattice Hamiltonians, we are able to dem…
