Time-of-flight expansion of binary Bose-Einstein condensates at finite temperature
Kean Loon Lee, Nils B. Jørgensen, Lars J. Wacker +4
Ultracold quantum gases provide a unique setting for studying and understanding the properties of interacting quantum systems. Here, we investigate a multi-component system of $^{8…
Landau Effective Interaction between Quasiparticles in a Bose-Einstein Condensate
A. Camacho-Guardian, Georg M. Bruun
Landau's description of the excitations in a macroscopic system in terms of quasiparticles stands out as one of the highlights in quantum physics. It provides an accurate descripti…
Coalescence of Two Impurities in a Trapped One-dimensional Bose Gas
A. S. Dehkharghani, A. G. Volosniev, N. T. Zinner
We study the ground state of a one-dimensional (1D) trapped Bose gas with two mobile impurity particles. To investigate this set-up, we develop a variational procedure in which the…
Giant optical nonlinearities from Rydberg-excitons in semiconductor microcavities
Valentin Walther, Robert Johne, Thomas Pohl
The realization of exciton-polaritons -- hybrid excitations of semiconductor quantum well excitons and cavity photons -- has been of great technological and scientific significance…
Effective three-body interactions for bosons in a double-well confinement
Jacek Dobrzyniecki, Xikun Li, Anne E. B. Nielsen +1
When describing the low-energy physics of bosons in a double-well potential with a high barrier between the wells and sufficiently weak atom-atom interactions, one can to a good ap…
Higher first Chern numbers in one dimensional Bose-Fermi mixtures
Kristian Knakkergaard Nielsen, Zhigang Wu, Georg M. Bruun
We propose to use a one-dimensional system consisting of identical fermions in a periodically driven lattice immersed in a Bose gas, to realise topological superfluid phases with C…
Emergence of junction dynamics in a strongly interacting Bose mixture
Rafael E. Barfknecht, Angela Foerster, Nikolaj T. Zinner
We study the dynamics of a one-dimensional system composed of a bosonic background and one impurity in single- and double-well trapping geometries. In the limit of strong interacti…
Bose polarons at finite temperature and strong coupling
Nils-Eric Guenther, Pietro Massignan, Maciej Lewenstein +1
The temperature dependence of a mobile impurity in a dilute Bose gas, the Bose polaron, is investigated for wide a range of impurity-bath interactions. Using a diagrammatic resumma…
Squeezing the Efimov effect
J. H. Sandoval, F. F. Bellotti, M. T. Yamashita +4
The quantum mechanical three-body problem is a source of continuing interest due to its complexity and not least due to the presence of fascinating solvable cases. The prime exampl…
Goldstone mode and pair-breaking excitations in atomic Fermi superfluids
Sascha Hoinka, Paul Dyke, Marcus G. Lingham +3
Spontaneous symmetry breaking is a central paradigm of elementary particle physics, magnetism, superfluidity and superconductivity. According to Goldstone's theorem, phase transiti…
A mixed dimensional Bose polaron
Niels Jakob Søe Loft, Zhigang Wu, Georg M. Bruun
A new generation of cold atom experiments trapping atomic mixtures in species selective optical potentials opens up the intriguing possibility to create systems in which different…
Quantum Simulation of Competing Orders with Fermions in Quantum Optical Lattices
Arturo Camacho-Guardian, Rosario Paredes, Santiago F. Caballero-Benitez
Ultracold Fermi atoms confined in optical lattices coupled to quantized modes of an optical cavity are an ideal scenario to engineer quantum simulators in the strongly interacting…
Time-reversal invariant topological superfluids in Bose-Fermi mixtures
Jonatan Melkær Midtgaard, Zhigang Wu, G. M. Bruun
A mixed dimensional system of fermions in two layers immersed in a Bose-Einstein condensate (BEC) is shown to be a promising setup to realise topological superfluids with time-reve…
Analytical and numerical studies of Bose-Fermi mixtures in a one-dimensional harmonic trap
A. S. Dehkharghani, F. F. Bellotti, N. T. Zinner
In this paper we study a mixed system of bosons and fermions with up to six particles in total. All particles are assumed to have the same mass. The two-body interactions are repul…
Four fermions in a one-dimensional harmonic trap: Accuracy of a variational-ansatz approach
Daniel Pęcak, Amin S. Dehkharghani, Nikolaj T. Zinner +1
Detailed analysis of the system of four interacting ultra-cold fermions confined in a one-dimensional harmonic trap is performed. The analysis is done in the framework of a simple…
Long range mediated interactions in a mixed dimensional system
Daniel Suchet, Zhigang Wu, Frédéric Chevy +1
We present a mixed-dimensional atomic gas system to unambiguously detect and systematically probe mediated interactions. In our scheme, fermionic atoms are confined in two parallel…
Mobile Spin Impurity in an Optical Lattice
C. W. Duncan, F. F. Bellotti, P. Öhberg +2
We investigate the Fermi polaron problem in a spin-1/2 Fermi gas in an optical lattice for the limit of both strong repulsive contact interactions and one dimension. In this limit,…
