A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

We perform a theoretical and experimental study of a system of two ultracold atoms with
tunable interaction in an elongated trapping potential. We show that the coupling of center-of …

A theoretical model is presented describing the confinement-induced resonances observed
in the recent loss experiment of Haller et al.[Phys. Rev. Lett. 104, 153203 (2010)]. These …

The exploration of dimensional crossover carries profound fundamental significance,
serving as a crucial bridge in comprehending the remarkable disparities observed in …

It is well known that the magnetic Feshbach resonances of cold atoms are sensitive to the
magnitude of the external magnetic field. Much less attention has been paid to the direction …

We investigate the effect of higher-order interactions induced by shape-dependent
confinement in the modulational instability (MI) of a binary mixture of Bose-Einstein …

The equation of state (EOS) for a pure two-dimensional (2D) Bose gas exhibits a logarithmic
dependence on the s-wave scattering length [L. Salasnich, Phys. Rev. Lett. 118, 130402 …

We analyze the impact of multichannel scattering in harmonic waveguides on the positions
and widths of confinement-induced resonances for both isotropic and anisotropic transversal …

The confinement-induced resonances for trapped bosons in the cigar-shaped and pancake
geometries are studied within the generalized Gross-Pitaevskii equations, which are a …

Dimensionality is a central concept in developing the theory of low-dimensional physics.
However, previous research on dimensional crossover in the context of a Bose–Einstein …
