Two-dimensional dipolar scattering

Thermodynamics of a two-dimensional Heisenberg ferromagnet with dipolar interaction

Density instabilities in a two-dimensional dipolar Fermi gas.

We study the density instabilities of a two-dimensional gas of dipolar fermions with aligned dipole moments. The random phase approximation (RPA) for the density-density response function is never accurate for the dipolar gas, and so we incorporate correlations beyond RPA via an improved version of the Singwi-Tosi-Land-Sjölander scheme. In addition to density-wave instabilities, our formalism c...

Stable Dilute Supersolid of Two-Dimensional Dipolar Bosons.

We consider two-dimensional bosonic dipoles oriented perpendicularly to the plane. On top of the usual two-body contact and long-range dipolar interactions we add a contact three-body repulsion as expected, in particular, for dipoles in the bilayer geometry with tunneling. The three-body repulsion is crucial for stabilizing the system, and we show that our model allows for stable continuous spa...

Loop scattering in two-dimensional QCD.

Using the integrability conditions that we recently obtained in QCD 2 with massless fermions, we arrive at a sufficient number of conservation laws to be able to fix the scattering amplitudes involving a local version of the Wilson loop operator.

Spectroscopy of dipolar fermions in layered two-dimensional and three-dimensional lattices

Motivated by ongoing measurements at JILA, we calculate the recoil-free spectra of dipolar interacting fermions, for example ultracold heteronuclear molecules, in a one-dimensional lattice of two-dimensional layers or “pancakes,” spectroscopically probing transitions between different internal (e.g., rotational) states. We additionally incorporate p-wave interactions and losses, which are impor...
