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 …

Lanthanide atoms have an unusual electron configuration, with a partially filled shell of f
orbitals. This leads to a set of characteristic properties, including large numbers of optical …

We study theoretically and experimentally the emergence of supersolid properties in a
dipolar Bose-Einstein condensate. The theory reveals a ground state phase diagram with …

Quantum fluctuations are the origin of genuine quantum many-body effects, and can be
neglected in classical mean-field phenomena. Here, we report on the observation of stable …

A supersolid is a counter-intuitive state of matter that combines the frictionless flow of a
superfluid with the crystal-like periodic density modulation of a solid,. Since the first …

Isolated quantum many-body systems with integrable dynamics generically do not
thermalize when taken far from equilibrium. As one perturbs such systems away from the …

We report on the first realization of heteronuclear dipolar quantum mixtures of highly
magnetic erbium and dysprosium atoms. With a versatile experimental setup, we …

Dipolar quantum droplets are exotic quantum objects that are self-bound due to the subtle
balance of attraction, repulsion, and quantum correlations. Here we present a systematic …

We demonstrate the emergence of a topological ordered phase for non-Hermitian systems.
Specifically, we elucidate that systems with non-Hermitian two-body interactions show a …

We describe the creation of a long-lived spin-orbit-coupled gas of quantum degenerate
atoms using the most magnetic fermionic element, dysprosium. Spin-orbit coupling arises …
