This article reviews theoretical and experimental advances in Efimov physics, an array of
quantum few-body and many-body phenomena arising for particles interacting via short …

In this report we discuss the dynamical response of heavy quantum impurities immersed in a
Fermi gas at zero and at finite temperature. Studying both the frequency and the time …

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 …

The emergence of quasiparticles in interacting matter represents one of the cornerstones of
modern physics. However, in the vicinity of a quantum critical point, the existence of …

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 …

Mobile impurities in a Bose-Einstein condensate form quasiparticles called polarons. Here,
we show that two such polarons can bind to form a bound bipolaron state. Its emergence is …

We analyze the dynamics of Bose polarons in the vicinity of a Feshbach resonance between
the impurity and host atoms. We compute the radio-frequency absorption spectra for the …

We monitor the correlated quench induced dynamical dressing of a spinor impurity
repulsively interacting with a Bose-Einstein condensate. Inspecting the temporal evolution of …

Mobile impurity atoms immersed in Bose–Einstein condensates provide a new platform for
exploring Bose polarons. Recent experimental advances in the field of ultracold atoms make …
