Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

Shape resonances play a central role in many areas of science, but the real-time
measurement of the associated many-body dynamics remains challenging. Here, we …

Shape resonances in physics and chemistry arise from the spatial confinement of a particle
by a potential barrier. In molecular photoionization, these barriers prevent the electron from …

We experimentally observe the collective excitation (called surface-mode excitation) of Bose–
Einstein condensate of 23 Na by ramping the external magnetic field across the high-partial …

We investigate the scattering properties and bound states of a quasi-two-dimensional (Q2D)
spin-polarized Fermi gas near ap-wave Feshbach resonance. Strong confinement promotes …

We report on the observation of dipolar splitting in Li 6 p-wave Feshbach resonances by
high-resolution atom-loss spectroscopy. The Feshbach resonances at 159, 185, and 215 G …

We investigate the role of the effective range on the bulk viscosity of s-and p-wave Fermi
gases. At resonance, the presence of the effective range breaks the scale invariance of the …

Orbital degrees of freedom play an essential role in metals, semiconductors, and strongly
confined electronic systems. Experiments with ultracold atoms have used highly anisotropic …

Magnetic Feshbach resonances are a key tool in the field of ultracold quantum gases, but
their full exploitation requires the generation of large, stable magnetic fields up to 1000 G …

In quantum mechanics, collisions between two particles are captured by a scattering matrix
which describes the transfer from an initial entrance state to an outgoing final state …
