This article is a review of recent developments in the phenomenological description of
unconventional superconductivity. Starting with the BCS theory of superconductivity with …

The realization of Bose Einstein condensates (BEC) and quantum degenerate Fermi gases
with cold atoms has been a highlight of quantum physics during the past decade. Cold …

Materials with multiple superconducting phases are rare. Here, we report the discovery of
two-phase unconventional superconductivity in CeRh2As2. Using thermodynamic probes …

Intermetallic compounds containing f-electron elements display a wealth of superconducting
phases, which are prime candidates for unconventional pairing with complex order …

Recent experimental progress in trap** and cooling of molecular gases boosts interest in
the interdisciplinary field of quantum gases with dominant dipole–dipole interactions. An …

Recent discoveries of new materials and improvements in calorimetric techniques have
given new impetus to the subject of specific heat. Nevertheless, there is a serious lack of …

'Conventional'superconductivity, as used in this review, refers to electron–phonon-coupled
superconducting electron pairs described by BCS theory. Unconventional superconductivity …

In condensed matter physics, spontaneous symmetry breaking has been a key concept, and
discoveries of new types of broken symmetries have greatly increased our understanding of …

The heavy-fermion compound UPt 3 is the first compelling example of a superconductor with
an order parameter of unconventional symmetry. To this day, it is the only unambiguous …

Measurements of the specific heat of Mg 11 B 2 from 1 to 50 K, in magnetic fields to 9 T, give
the Debye temperature, Θ= 1050 K, the coefficient of the normal-state electron contribution, γ …
