Pseudopotential for the 2D contact interaction
T. M. Whitehead, L. M. Schonenberg, N. Kongsuwan +2
We propose a smooth pseudopotential for the contact interaction acting between ultracold atoms confined to two dimensions. The pseudopotential reproduces the scattering properties…
Pseudopotentials for an ultracold dipolar gas
T. M. Whitehead, G. J. Conduit
A gas of ultracold molecules interacting via the long-range dipolar potential offers a highly controlled environment in which to study strongly correlated phases. However, at parti…
High-fidelity pseudopotentials for the contact interaction
P. O. Bugnion, P. López Ríos, R. J. Needs +1
The contact interaction is often used in modeling ultracold atomic gases, although it leads to pathological behavior arising from the divergence of the many-body wavefunction when…
Exploring exchange mechanisms with a cold atom gas
P. O. Bugnion, G. J. Conduit
Fermionic atoms trapped in a double well potential are an ideal setting to study fundamental exchange mechanisms. We use exact diagonalization and complementary analytic calculatio…
Ferromagnetic spin correlations in a few-fermion system
P. O. Bugnion, G. J. Conduit
We study the spin correlations of a few fermions in a quasi one-dimensional trap. Exact diagonalization calculations demonstrate that repulsive interactions between the two species…
Itinerant ferromagnetism in an interacting Fermi gas with mass imbalance
C. W. von Keyserlingk, G. J. Conduit
We study the emergence of itinerant ferromagnetism in an ultra-cold atomic gas with a variable mass ratio between the up and down spin species. Mass imbalance breaks the SU(2) spin…
