Special Issue Information

Dear Colleagues,

This Special Issue is dedicated to SuperFluctuations 2017, which will be held in San Benedetto del Tronto, Italy, 6–8 September 2017 (http://www.multisuper.org/superfluctuations-2017).

Among the main topics of the Conference 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 Conference 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.

Main Topics:

  • -Fluctuations and BCS-BEC crossover phenomena in low dimensional systems;
  • -Hybrid systems, superconductivity at the interfaces, and coexistence of phases;
  • -Highly nonlinear phenomena: Josephson and Andreev effects, topological defects, skyrmions and solitons, vortex states;
  • -Novel phenomena in multicomponent/multigap superconductors and superfluids.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Condensed Matter is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) is waived for well-prepared manuscripts submitted to this issue. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
