Neutron polaron as a constraint on nuclear density functionals

MM Forbes, A Gezerlis, K Hebeler, T Lesinski… - Physical Review C, 2014 - APS
We study the energy of an impurity (polaron) that interacts strongly in a sea of fermions when
the effective range of the impurity-fermion interaction becomes important, thereby mapping …

Dipolar-induced resonance for ultracold bosons in a quasi-one-dimensional optical lattice

N Bartolo, DJ Papoular, L Barbiero, C Menotti… - Physical Review A …, 2013 - APS
We study the role of the dipolar-induced resonance (DIR) in a quasi-one-dimensional
system of ultracold bosons. We first describe the effect of the DIR on two particles in a …

Itinerant ferromagnetism with finite-ranged interactions

CW von Keyserlingk, GJ Conduit - Physical Review B—Condensed Matter and …, 2013 - APS
Quantum fluctuations are of central importance in itinerant ferromagnets; when modeled by
a homogeneous electron gas with contact interactions, fluctuations deliver a rich phase …

Fermion pairing across a dipolar interaction induced resonance

R Qi, ZY Shi, H Zhai - Physical Review Letters, 2013 - APS
It is known from the solution of the two-body problem that an anisotropic dipolar interaction
can give rise to s-wave scattering resonances, which are named dipolar interaction induced …

Ultracold Fermi gases with resonant dipole-dipole interaction

T Shi, SH Zou, H Hu, CP Sun, S Yi - Physical Review Letters, 2013 - APS
The superfluid phases in resonant dipolar Fermi gases are investigated by the standard
mean-field theory. In contrast to the crossover from Bose-Einstein condensation (BEC) to …

Many-body properties of quasi–one-dimensional boson gas across a narrow CIR

R Qi, X Guan - Europhysics Letters, 2013 - iopscience.iop.org
We study strong interaction effects in a one-dimensional (1D) boson gas across a narrow
confinement-induced resonance (CIR). In contrast to the zero-range potential, the 1D two …

Quasi-one-dimensional dipolar quantum gases

L Guan, X Cui, R Qi, H Zhai - Physical Review A, 2014 - APS
In this paper we consider dipolar quantum gases in a quasi-one-dimensional tube with
dipole moment perpendicular to the tube direction. We deduce the effective one …

Iterative evaluation of the effect of long-range potentials on the solution of the Schrödinger equation

G Rawitscher - Physical Review A—Atomic, Molecular, and Optical …, 2013 - APS
There are cases where the potentials present in the Schrödinger equation are of long range
and have measurable effects as, for instance, for the interaction between atoms at low …

Matter waves in two-dimensional arbitrary atomic crystals

N Bartolo, M Antezza - Physical Review A, 2014 - APS
We present a general scheme to realize a cold-atom quantum simulator of bidimensional
atomic crystals. Our model is based on the use of two independently trapped atomic species …

Effect of the short-range interaction on low-energy collisions of ultracold dipoles

P Zhang, J Jie - Physical Review A, 2014 - APS
We consider the low-energy scattering of two ultracold polarized dipoles with both a short-
range interaction (SRI) and a weak dipole-dipole interaction (DDI), which is far away from …
