We review the physics of pair-density wave (PDW) superconductors. We begin with a
macroscopic description that emphasizes order induced by PDW states, such as charge …

This report addresses topics and questions of common interest in the fields of ultra-cold
gases and nuclear physics in the context of the BCS–BEC crossover. By this crossover, the …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

The current status of theoretical studies on the quantum chromodynamics (QCD) phase
diagram at finite temperature and baryon chemical potential is reviewed with special …

The physics of quantum degenerate atomic Fermi gases in uniform as well as in
harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is …

Investigations of deconfined quark matter within NJL-type models are reviewed, focusing on
the regime of low temperatures and “moderate” densities, which is not accessible by …

We established superfluidity in a two-state mixture of ultracold fermionic atoms with
imbalanced state populations. This study relates to the long-standing debate about the …

Inhomogeneous superconductivity arises when the species participating in the pairing
phenomenon have different Fermi surfaces with a large enough separation. In these …

We report the observation of pairing in a gas of atomic fermions with unequal numbers of
two components. Beyond a critical polarization, the gas separates into a phase that is …

Nuclear matter and finite nuclei exhibit the property of superfluidity by forming Cooper pairs.
We review the microscopic theories and methods that are being employed to understand the …
