Polaron quasiparticles are formed when a mobile impurity is coupled to the elementary
excitations of a many-particle background. In the field of ultracold atoms, the study of the …

Understanding the electron pairing in hole-doped cuprate superconductors has been a
challenge, in particular because the “normal” state from which it evolves is unprecedented …

In the last decade, quantum simulators, and in particular cold atoms in optical lattices, have
emerged as a valuable tool to study strongly correlated quantum matter. These experiments …

The emergence of quasiparticles in quantum many-body systems underlies the rich
phenomenology in many strongly interacting materials. In the context of doped Mott …

The competition between antiferromagnetism and hole motion in two-dimensional Mott
insulators lies at the heart of a doping-dependent transition from an anomalous metal to a …

Polarons—electronic charge carriers 'dressed'by a local polarization of the background
environment—are among the most fundamental quasiparticles in interacting many-body …

Quantum interference can deeply alter the nature of many-body phases of matter. In the
case of the Hubbard model, Nagaoka proved that introducing a single itinerant charge can …

Understanding strongly correlated quantum many-body states is one of the most difficult
challenges in modern physics. For example, there remain fundamental open questions on …

Quantum gas microscopes for ultracold atoms can provide high-resolution real-space
snapshots of complex many-body systems. We implement machine learning to analyse and …

The Hubbard model of attractively interacting fermions provides a paradigmatic setting for
fermion pairing. It features a crossover between Bose-Einstein condensation of tightly bound …
