While a number of experiments use heated sapphire windows to reduce strontium deposition and increase the viewport lifetime, here we study another possibility, consisting of sending the laser beam into the atomic flux by reflecting it off a mirror at 45 degree exposed to the strontium flux. We present our attempt to find a substrate that can be exposed to strontium and maintain high reflectivity.

We focus on selective reflection, one of the main spectroscopic probes of Casimir-Polder interactions. We calculate selective reflection spectra using the full, distance dependent, Casimir-Polder energy shift and linewidth.

We study spin mixing dynamics in a chromium dipolar Bose-Einstein condensate, after tilting the atomic spins by an angle 𝜃 with respect to the magnetic field.

We study the impact of spin-exchange collisions on the dynamics of Bose-Einstein condensation by rapidly cooling a chromium multicomponent Bose gas.

We analyze the spin dynamics of an out-of-equilibrium large spin dipolar atomic Bose gas in an optical lattice. We observe a smooth crossover from a complex oscillatory behavior to an exponential behavior throughout the Mott-to-superfluid transition.

The effect of dipolar orientation with respect to the soliton plane on the physics of two-dimensional bright solitons in dipolar Bose-Einstein condensates is discussed.
