This Special Issue of Condensed Matter is dedicated to charge, spin, and pair fluctuations and other highly non-linear phenomena in novel superfluid and superconducting systems.
Among the main topics of the Special Issue is the study of fluctuations and BCS-BEC crossover phenomena in low dimensional systems. Very recently, the BCS-BEC crossover has been realized in quasi two-dimensional (2D) ultracold gases made of alkali-metal atoms. Contrary to the 3D case, mean-field theories are completely unreliable for the study of strongly-interacting superfluid fermions in two dimensions because of the huge increase of quantum fluctuations. The 2D BCS-BEC crossover is also interesting for high-Tc superconductivity where the phase diagram of cuprate superconductors can be interpreted in terms of a BCS-BEC crossover as doping is varied. The critical temperature Tc has a wide fluctuation region with pseudo-gap effects not yet fully understood.
Another hot topic of the Special Issue is multiband and multigap superconductors, which have demonstrated the potential for realizing novel coherent quantum phenomena and to control system parameters to enhance the superconducting critical temperature and the pairing energy gaps. Nanostructuring of bulk superconductors in the form of nanofilms, nanostripes, and nanoclusters, or introducing controlled non homogeneities has shown to be able to induce multi-gap and multiband superconductivity and superconducting shape resonances. Very recently, it has been suggested that iron-based superconductors have composite superconductivity, consisting of strong-coupling BEC in the electron band and weak-coupling BCS-like superconductivity in the hole band. Indeed, the intermediate crossover regime between BCS and BEC superconductivity is now considered as one of the most promising regimes in the search for high-Tc superconductivity.
