Finite Range Effects in Energies and Recombination Rates of Three Identical Bosons
P. K. Sørensen, D. V. Fedorov, A. S. Jensen +1
We investigate finite-range effects in systems with three identical bosons. We calculate recombination rates and bound state spectra using two different finite-range models that ha…
Efimov States of Heavy Impurities in a Bose-Einstein Condensate
N. T. Zinner
We consider the problem of two heavy impurity particles embedded in a gas of weakly-interacting light mass bosonic particles in the condensed state. Using the Bogoliubov approach t…
Mass-imbalanced Three-Body Systems in Two Dimensions
F. F. Bellotti, T. Frederico, M. T. Yamashita +3
We consider three-body systems in two dimensions with zero-range interactions for general masses and interaction strengths. The momentum-space Schrödinger equation is solved numeri…
Occurrence conditions for two-dimensional Borromean systems
A. G. Volosniev, D. V. Fedorov, A. S. Jensen +1
We search for Borromean three-body systems of identical bosons in two dimensional geometry, i.e. we search for bound three-boson system without bound two-body subsystems. Unlike th…
Dimensional Effects on the Momentum distribution of Bosonic Trimer States
F. F. Bellotti, T. Frederico, M. T. Yamashita +3
The momentum distribution is a powerful probe of strongly-interacting systems that are expected to display universal behavior. This is contained in the contact parameters which rel…
Universal properties of Fermi gases in arbitrary dimensions
Manuel Valiente, Nikolaj T. Zinner, Klaus Molmer
We consider spin-1/2 Fermi gases in arbitrary, integer or non-integer spatial dimensions, interacting via a Dirac delta potential. We first generalize the method of Tan's distribut…
