Doped SrTiO 3, one of the most dilute bulk systems to display superconductivity, is perhaps the first example of an unconventional superconductor, as it does not fit into the standard …
The most well-known example of an ordered quantum state—superconductivity—is caused by the formation and condensation of pairs of electrons. Fundamentally, what distinguishes …
The Th 7 Fe 3 family of superconductors provides a rich playground for unconventional superconductivity. La 7 Ni 3 is the latest member of this family, which we here investigate by …

Multicomponent spin-singlet superconductors with competing 0-and π-pairing couplings, as in s++ and s±phases, are close to instabilities with a spontaneous breaking of time-reversal …
We consider nonreciprocal supercurrent effects in Josephson junctions based on multiband superconductors with a pairing structure that can break time-reversal symmetry. We …
Recent experiments [Grinenko et al. Nat. Phys. 17, 1254 (2021) NPAHAX 1745-2473 10.1038/s41567-021-01350-9] reported the observation of a condensate of four-fermion …
Two-band superconductors exhibit a distinct phase characterized by two correlation lengths, one smaller and the other larger than the magnetic field penetration length. This regime was …
Detection of a bosonic metallic state that breaks the Z 2 time-reversal symmetry has been recently reported in Ba 1− x K x Fe 2 As 2 with a doping level x≈ 0.8. This is a metallic state …

It is well-established that multicomponent superconductors can host different nonstandard phenomena such as broken-time reversal symmetry (BTRS) states, exotic Fulde–Ferrell …
