Dipolar particles in a double-trap confinement: Response to tilting the dipolar orientation
J. Bjerlin, J. Bengtsson, F. Deuretzbacher +2
We analyze the microscopic few-body properties of dipolar particles confined in two parallel quasi-one-dimensional harmonic traps. In particular, we show that an adiabatic rotation…
Finite-size effects in the dynamics of few bosons in a ring potential
G. Eriksson, J. Bengtsson, E. Ö. Karabulut +2
We study the temporal evolution of a small number of ultra-cold bosonic atoms confined in a ring potential. Assuming that initially the system is in a solitary-wave solution of…
Spin-chain model for strongly interacting one-dimensional Bose-Fermi mixtures
F. Deuretzbacher, D. Becker, J. Bjerlin +2
Strongly interacting one-dimensional (1D) Bose-Fermi mixtures form a tunable XXZ spin chain. Within the spin-chain model developed here, all properties of these systems can be calc…
Few-body precursor of the Higgs mode in a superfluid Fermi gas
J. Bjerlin, S. M. Reimann, G. M. Bruun
We demonstrate that an undamped few-body precursor of the Higgs mode can be investigated in a harmonically trapped Fermi gas. Using exact diagonalisation, the lowest monopole mode…
Density functional theory for strongly-correlated bosonic and fermionic ultracold dipolar and ionic gases
F. Malet, A. Mirtschink, C. B. Mendl +4
We introduce a density functional formalism to study the ground-state properties of strongly-correlated dipolar and ionic ultracold bosonic and fermionic gases, based on the self-c…
Self-bound many-body states of quasi-one-dimensional dipolar Fermi gases: Exploiting Bose-Fermi mappings for generalized contact interactions
F. Deuretzbacher, G. M. Bruun, C. J. Pethick +3
Using a combination of results from exact mappings and from mean-field theory we explore the phase diagram of quasi-one-dimensional systems of identical fermions with attractive di…
Total Current Blockade in an Ultra-Cold Dipolar Quantum Wire
Líney Halla Kristinsdóttir, Olov Karlström, Johannes Bjerlin +4
Cold atom systems offer a great potential for the future design of new mesoscopic quantum systems with properties that are fundamentally different from semiconductor nanostructures…
Spin-orbit-enhanced Wigner localization in quantum dots
A. Cavalli, F. Malet, J. C. Cremon +1
We investigate quantum dots with Rashba spin-orbit coupling in the strongly-correlated regime. We show that the presence of the Rashba interaction enhances the Wigner localization…
Bosonic and fermionic dipoles on a ring
Sascha Zöllner, G. M. Bruun, C. J. Pethick +1
We show that dipolar bosons and fermions confined in a quasi-one-dimensional ring trap exhibit a rich variety of states because their interaction is inhomogeneous. For purely repul…
Tunable Wigner States with Dipolar Atoms and Molecules
J. C. Cremon, G. M. Bruun, S. M. Reimann
We study the few-body physics of trapped atoms or molecules with electric or magnetic dipole moments aligned by an external field. Using exact numerical diagonalization appropriate…
Transport and interaction blockade of cold bosonic atoms in a triple-well potential
P. Schlagheck, F. Malet, J. C. Cremon +1
We theoretically investigate the transport properties of cold bosonic atoms in a quasi one-dimensional triple-well potential that consists of two large outer wells, which act as mi…
Uniform semiclassical trace formula for U(3) --> SO(3) symmetry breaking
M. Brack, M. Ögren, Y. Yu +1
We develop a uniform semiclassical trace formula for the density of states of a three-dimensional isotropic harmonic oscillator (HO), perturbed by a term . This term b…
