A review is given of various theoretical approaches for the equation of state (EoS) of dense
matter, relevant for the description of core-collapse supernovae, compact stars, and compact …

In this review, we discuss the properties of a few impurity atoms immersed in a gas of
ultracold fermions—the so-called Fermi polaron problem. On one hand, this many-body …

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 …

One of the greatest challenges in modern physics is to understand the behaviour of an
ensemble of strongly interacting particles. A class of quantum many-body systems (such as …

A Fermi gas of atoms with resonant interactions is predicted to obey universal
hydrodynamics, in which the shear viscosity and other transport coefficients are universal …

We study the thermal evolution of a highly spin-imbalanced, homogeneous Fermi gas with
unitarity limited interactions, from a Fermi liquid of polarons at low temperatures to a …

We present a self-consistent theory for the thermodynamics of the BCS-BEC crossover in the
normal and superfluid phase which is both conserving and gapless. It is based on the …

Strongly correlated quantum fluids are phases of matter that are intrinsically quantum
mechanical and that do not have a simple description in terms of weakly interacting …

Precise understanding of strongly interacting fermions, from electrons in modern materials to
nuclear matter, presents a major goal in modern physics. However, the theoretical …

We have measured the heat capacity of an optically trapped, strongly interacting Fermi gas
of atoms. A precise addition of energy to the gas is followed by single-parameter …
