Weakly bound atomic trimers in ultracold traps
(2003-01-01)
The experimental three-atom recombination coefficients of the atomic states [Formula Presented] [Formula Presented] and [Formula Presented] together with the corresponding two-body scattering lengths, allow predictions of ...
Ultracold collisions between two light indistinguishable diatomic molecules: Elastic and rotational energy transfer in HD+HD
(2012-05-03)
A close coupling quantum-mechanical calculation is performed for rotational energy transfer in a HD+HD collision at very low energy, down to the ultracold temperatures: T∼10 -8 K. A global six-dimensional H 2-H 2 ...

Non-Hermitian multichannel theory of ultracold collisions modified by intense light fields tuned to the red of the trapping transition
(1998-01-01)
We develop a systematic scheme to treat binary collisions between ultracold atoms in the presence of a strong laser field, tuned to the red of the trapping transition. We assume that the Rabi frequency is much less than ...
Ultracold bosons in random lattice potentials
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2023-04-06)
The Bose-Hubbard model describes short-range interacting spinless bosons on a random lattice. This model is realized in ultracold atomic systems where quantum phase transitions can be observed. When loaded into a deep ...
Mass-imbalanced three-body systems in two dimensions
(2013-03-14)
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 numerically and in the Born-Oppenheimer (BO) ...
