Multi-particle instability in a spin-imbalanced Fermi gas
T. M. Whitehead, G. J. Conduit
Weak attractive interactions in a spin-imbalanced Fermi gas induce a multi-particle instability, binding multiple fermions together. The maximum binding energy per particle is achi…
Jastrow correlation factor for periodic systems
T. M. Whitehead, M. H. Michael, G. J. Conduit
We propose a Jastrow factor for electron-electron correlations that interpolates between the radial symmetry of the Coulomb interaction at short inter-particle distance and the spa…
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…
Pseudopotential for the electron-electron interaction
J. H. Lloyd-Williams, R. J. Needs, G. J. Conduit
We propose a pseudopotential for the electron-electron Coulomb interaction to improve the efficiency of many-body electronic structure calculations. The pseudopotential accurately…
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…
