We report on the observation of confinement-induced resonances in strongly interacting
quantum-gas systems with tunable interactions for one-and two-dimensional geometry …

Understanding the effect of correlations in interacting many-body systems is one of the main
challenges in quantum mechanics. While the general problem can only be addressed by …

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 …

We study a spin-polarized degenerate Fermi gas interacting via ap-wave Feshbach
resonance in an optical lattice. The strong confinement available in this system allows us to …

We present an experimental investigation of collective oscillations in harmonically trapped
Fermi gases through the crossover from two to three dimensions. Specifically, we measure …

We demonstrate that virtual excitations of higher radial modes in an atomic Bose gas in a
tightly confining waveguide result in effective three-body collisions that violate integrability in …

We experimentally investigate the mix-dimensional scattering occurring when the collisional
partners live in different dimensions. We employ a binary mixture of ultracold atoms and …

Elongated atom traps can confine ultracold gases in the quasi-one-dimensional regime. We
review both the theory of these atom waveguides and their experimental realizations, with …

It was recently predicted [Phys. Rev. Lett. 81, 938 (1998) PRLTAO 0031-9007
10.1103/PhysRevLett. 81.938] that atom-atom scattering under transverse harmonic …

We have observed two-particle bound states of atoms confined in a one-dimensional matter
waveguide. These bound states exist irrespective of the sign of the scattering length …
