Coexistence of density wave and superfluid order in a dipolar Fermi gas
Zhigang Wu, Jens K. Block, Georg M. Bruun
We analyse the coexistence of superfluid and density wave (stripe) order in a quasi-two-dimensional gas of dipolar fermions aligned by an external field. Remarkably, the anisotropi…
Universality of three-body systems in 2D: parametrization of the bound states energies
F. F. Bellotti, T. Frederico, M. T. Yamashita +3
Universal properties of mass-imbalanced three-body systems in 2D are studied using zero-range interactions in momentum space. The dependence of the three-particle binding energy on…
Mass-imbalanced Three-body Systems in 2D: bound states and the analytical approach to the adiabatic potential
F. F. Bellotti, T. Frederico, M. T. Yamashita +3
Three-body systems in two dimensions with zero-range interactions are considered for general masses and interaction strengths. The problem is formulated in momentum space and the n…
A variational approach to repulsively interacting three-fermion systems in a one-dimensional harmonic trap
N. J. S. Loft, A. S. Dehkharghani, N. P. Mehta +2
We study a three-body system with zero-range interactions in a one-dimensional harmonic trap. The system consists of two spin-polarized fermions and a third particle which is disti…
High-temperature limit of the resonant Fermi gas
V. Ngampruetikorn, Meera M. Parish, Jesper Levinsen
We use the virial expansion to investigate the behavior of the two-component, attractive Fermi gas in the high-temperature limit, where the system smoothly evolves from weakly attr…
Quantum magnetism in strongly interacting one-dimensional spinor Bose systems
A. S. Dehkharghani, A. G. Volosniev, E. J. Lindgren +5
Strongly interacting one-dimensional quantum systems often behave in a manner that is distinctly different from their higher-dimensional counterparts. When a particle attempts to m…
