Interacting bosonic flux ladders with a synthetic dimension: Ground-state phases and quantum quench dynamics

Maximilian Buser, Claudius Hubig, Ulrich Schollwöck +2

Flux ladders constitute the minimal setup enabling a systematic understanding of the rich physics of interacting particles subjected simultaneously to strong magnetic fields and a…

Self-Trapped Polarons and Topological Defects in a Topological Mott Insulator

Sergi Julià-Farré, Markus Müller, Maciej Lewenstein +1

Many-body interactions in topological quantum systems can give rise to new phases of matter, which simultaneously exhibit both rich spatial features and topological properties. In…

Mobile impurity in a Bose-Einstein condensate and the orthogonality catastrophe

Nils-Eric Guenther, Richard Schmidt, Georg M. Bruun +2

We analyze the properties of an impurity in a dilute Bose-Einstein condensate (BEC). First the quasiparticle residue of a static impurity in an ideal BEC is shown to vanish with in…

Dynamical solitons and boson fractionalization in cold-atom topological insulators

Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +2

We study the Bose-Hubbard model at incommensurate densities, which describes a one-dimensional system of interacting bosons whose tunneling is dressed by a dynamical…

Quantum droplets of bosonic mixtures in a one-dimensional optical lattice

Ivan Morera, Grigori E. Astrakharchik, Artur Polls +1

We demonstrate the existence of quantum droplets in two-component one-dimensional Bose-Hubbard chains. The droplets exist for any strength of repulsive intra-species interactions p…

Detecting topology through dynamics in interacting fermionic wires

Andreas Haller, Pietro Massignan, Matteo Rizzi

We describe a protocol to read out the topological invariant of interacting 1D chiral models, based on measuring the mean chiral displacement of time-evolving bulk excitations. We…
