Counterflow dynamics of two correlated impurities immersed in a bosonic gas
Friethjof Theel, Simeon I. Mistakidis, Kevin Keiler +1
The counterflow dynamics of two correlated impurities in a double-well coupled to an one-dimensional bosonic medium is explored. We determine the ground state phase diagram of the…
Entangling lattice-trapped bosons with a free impurity: impact on stationary and dynamical properties
Maxim Pyzh, Kevin Keiler, Simeon I. Mistakidis +1
We address the interplay of few lattice trapped bosons interacting with an impurity atom in a box potential. For the ground state, a classification is performed based on the fideli…
Impurity induced quantum chaos for an ultracold bosonic ensemble in a double-well
Jie Chen, Kevin Keiler, Gao Xianlong +1
We demonstrate that an ultracold many-body bosonic ensemble confined in a one-dimensional (1D) double-well (DW) potential can exhibit chaotic dynamics due to the presence of a sing…
Electric field-induced wave-packet dynamics and geometrical rearrangement of trilobite Rydberg molecules
Frederic Hummel, Kevin Keiler, Peter Schmelcher
We investigate the quantum dynamics of ultra-long-range trilobite molecules exposed to homogeneous electric fields. A trilobite molecule consists of a Rydberg atom and a ground-sta…
Polarons and their induced interactions in highly imbalanced triple mixtures
Kevin Keiler, Simeon I. Mistakidis, Peter Schmelcher
We unravel the polaronic properties of impurities immersed in a correlated trapped one-dimensional (1D) Bose-Bose mixture. This setup allows for the impurities to couple either att…
Many-body collisional dynamics of impurities injected into a double-well trapped Bose-Einstein condensate
Friethjof Theel, Kevin Keiler, Simeon I. Mistakidis +1
We unravel the many-body dynamics of a harmonically trapped impurity colliding with a bosonic medium confined in a double-well upon quenching the initially displaced harmonic trap…
Doping a lattice-trapped bosonic species with impurities: From ground state properties to correlated tunneling dynamics
Kevin Keiler, Simeon I. Mistakidis, Peter Schmelcher
We investigate the ground state properties and the nonequilibrium dynamics of a lattice trapped bosonic mixture consisting of an impurity species and a finite-sized medium. For the…
Entanglement-assisted tunneling dynamics of impurities in a double well immersed in a bath of lattice trapped bosons
Friethjof Theel, Kevin Keiler, Simeon I. Mistakidis +1
We unravel the correlated tunneling dynamics of an impurity trapped in a double well and interacting repulsively with a majority species of lattice trapped bosons. Upon quenching t…
Interaction induced single impurity tunneling in a binary mixture of trapped ultracold bosons
Kevin Keiler, Peter Schmelcher
We investigate the tunneling dynamics of an ultracold bosonic impurity species which interacts repulsively with a second, larger Bose gas. Both species are held in a finite-sized q…
Dynamical Pruning of the Non-Equilibrium Quantum Dynamics of Trapped Ultracold Bosons
F. Köhler, K. Keiler, S. I. Mistakidis +2
The investigation of the nonequilibrium quantum dynamics of bosonic many-body systems is very challenging due to the excessively growing Hilbert space and poses a major problem for…
State engineering of impurities in a lattice by coupling to a Bose gas
Kevin Keiler, Peter Schmelcher
We investigate the localization pattern of interacting impurities, which are trapped in a lattice potential and couple to a Bose gas. For small interspecies interaction strengths,…
Correlation induced localization of lattice trapped bosons coupled to a Bose-Einstein condensate
Kevin Keiler, Sven Krönke, Peter Schmelcher
We investigate the ground state properties of a lattice trapped bosonic system coupled to a Lieb-Liniger type gas. Our main goal is the description and in depth exploration and ana…
