Dynamical realization of magnetic states in a strongly interacting Bose mixture
Rafael E. Barfknecht, Angela Foerster, Nikolaj T. Zinner
We describe the dynamical preparation of magnetic states in a strongly interacting two-component Bose gas in a harmonic trap. By mapping this system to an effective spin chain mode…
Quantum collision theory in flat bands
Manuel Valiente, Nikolaj Thomas Zinner
We consider quantum scattering of particles in media exhibiting strong dispersion degeneracy. In particular, we study flat-banded lattices and linearly dispersed energy bands. The…
Spin Localization of a Fermi Polaron in a Quasirandom Optical Lattice
Callum W. Duncan, Niels J. S. Loft, Patrik Öhberg +2
Recently, the topics of many-body localization (MBL) and one-dimensional strongly interacting few-body systems have received a lot of interest. These two topics have been largely d…
Topological superfluidity of lattice fermions inside a Bose-Einstein condensate
Jonatan Melkær Midtgaard, Zhigang Wu, G. M. Bruun
We calculate the phase diagram of identical fermions in a 2-dimensional (2D) lattice immersed in a 3D Bose-Einstein condensate (BEC). The fermions exchange density fluctuations in…
Topological superfluid in a Fermi-Bose mixture with a high critical temperature
Zhigang Wu, Georg M. Bruun
We show that a two-dimensional (2D) spin-polarised Fermi gas immersed in a 3D Bose-Einstein condensate (BEC) constitutes a very promising system to realise a superfluid.…
Composite-boson approach to molecular Bose-Einstein condensates in mixtures of ultracold Fermi gases
P. Alexander Bouvrie, Malte C. Tichy, Itzhak Roditi
We show that an ansatz based on independent composite bosons [Phys. Rep. 463, 215 (2008)] accurately describes the condensate fraction of molecular Bose-Einstein condensates in ult…
Multiple scattering dynamics of fermions at an isolated p-wave resonance
Ryan Thomas, Kris O. Roberts, Eite Tiesinga +4
The wavefunction for indistinguishable fermions is anti-symmetric under particle exchange, which directly leads to the Pauli exclusion principle, and hence underlies the structure…
Comparing numerical and analytical approaches to strongly interacting two-component mixtures in one dimensional traps
F. F. Bellotti, A. S. Dehkharghani, N. T. Zinner
We investigate one-dimensional harmonically trapped two-component systems for repulsive interaction strengths ranging from the non-interacting to the strongly interacting regime fo…
Phase Separation and Dynamics of two-component Bose-Einstein condensates
Kean Loon Lee, Nils B. Jørgensen, I-Kang Liu +3
The miscibility of two interacting quantum systems is an important testing ground for the understanding of complex quantum systems. Two-component Bose-Einstein condensates enable t…
Observation of Attractive and Repulsive Polarons in a Bose-Einstein Condensate
Nils B. Jørgensen, Lars Wacker, Kristoffer T. Skalmstang +5
The problem of an impurity particle moving through a bosonic medium plays a fundamental role in physics. However, the canonical scenario of a mobile impurity immersed in a Bose-Ein…
Universal three-body physics in ultracold KRb mixtures
L. J. Wacker, N. B. Jørgensen, D. Birkmose +5
Ultracold atomic gases have recently become a driving force in few-body physics due to the observation of the Efimov effect. While initially observed in equal mass systems, one exp…
CONAN -- the cruncher of local exchange coefficients for strongly interacting confined systems in one dimension
N. J. S. Loft, L. B. Kristensen, A. E. Thomsen +2
We consider a one-dimensional system of particles with strong zero-range interactions. This system can be mapped onto a spin chain of the Heisenberg type with exchange coefficients…
Correlation properties of a three-body bosonic mixture in a harmonic trap
R. E. Barfknecht, A. S. Dehkharghani, A. Foerster +1
We make use of a simple pair correlated wave function approach to obtain results for the ground-state densities and momentum distribution of a one-dimensional three-body bosonic sy…
