Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

The foundation of atomic physics is the arsenal of spectroscopic tools to probe individual
atoms and molecules with astounding precision. With the advent of ultracold quantum …

The problem of an impurity particle moving through a bosonic medium plays a fundamental
role in physics. However, the canonical scenario of a mobile impurity immersed in a Bose …

When an impurity is immersed in a Bose-Einstein condensate, impurity-boson interactions
are expected to dress the impurity into a quasiparticle, the Bose polaron. We superimpose …

We implement imaging spectroscopy of the optical clock transition of lattice-trapped
degenerate fermionic Sr in the Mott-insulating regime, combining micron spatial resolution …

Vector solitons are a type of solitary or nonspreading wave packet occurring in a nonlinear
medium composed of multiple components. As such, a variety of synthetic systems can be …

Ultracold gases provide an unprecedented level of control for the investigation of soliton
dynamics and collisions. We present a scheme for deterministically preparing pairs of three …

Coherent conversion of photons to magnons, and back, provides a natural mechanism for
rapid control of interactions between stationary spins with long coherence times and high …

When global continuous symmetries are spontaneously broken, there appear gapless
collective excitations called Nambu–Goldstone modes (NGMs) that govern the low-energy …

Interactions in an ultracold boson-fermion mixture are often manifested by elastic collisions.
In a mixture of a condensed Bose gas (BEC) and spin polarized degenerate Fermi gas …
