Special Issue Information

Dear Colleagues,

This Special Issue will publish selected papers from the QCM 2018 conference lectures, joint with the QCM school, 10–16 June, 2018, in Rome, Italy. You are invited to submit a full manuscript for consideration and possible publication in this joint Special Issue. Submissions will be rapidly reviewed and published immediately, free of charge, if accepted. A second issue is reserved for contributions on the same topics that were not presented at the Rome conference or school.

The international conference, joint with the school on Quantum Complex Matter 2018 (QCM2018, http://www.superstripes.net/quantum-complex-matter-2018), will highlight recent advances in all major fields in quantum phenomena in complex condensed matter. This is a multi-purpose meeting of activities based on the Frontiers of Condensed Matter Physics (FCMP) lecture courses and selected topics of Superstripes conferences. Invited and leading contributed papers will focus on research sub-fields of:

Correlated electronic systems:

  • unconventional superconductivity
  • novel magnetism
  • Mott transition
  • quantum criticality
  • multi-band Hubbard model
  • Lifshitz transitions

Nano science:

  • graphene
  • TMDC
  • QHE
  • Topological
  • 2-D materials
  • Fano resonances

Spintronics:

  • Skyrmions
  • itinerant electron
  • magnetism
  • spin current
  • magnetic memory

Cold atoms:

  • Feshbach Resonance
  • Hubbard Model
  • BEC-BCS crossover

to promote discussion and collaboration among researchers of different sub-fields. The QCM 2018 conference is integrated with the QCM 2018 school with educational courses for students and young researchers. The lecture contents of the course will be announced later.

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.

Abstract
We investigate the ground state of strongly correlated electron systems based on an optimization variational Monte Carlo method to clarify the mechanism of high-temperature superconductivity.

We investigate the ground state of strongly correlated electron systems based on an optimization variational Monte Carlo method to clarify the mechanism of high-temperature superconductivity. The wave function is optimized by introducing variational parameters in an exponential-type wave function beyond the Gutzwiller function. The many-body effect plays an important role as an origin of superconductivity in a correlated electron system. There is a crossover between weakly correlated region and strongly correlated region, where two regions are characterized by the strength of the on-site Coulomb interaction U. We insist that high-temperature superconductivity occurs in the strongly correlated region. Full article

The spin galvanic effect (SGE) describes the conversion of a non-equilibrium spin polarization into a charge current and has recently attracted renewed interest due to the large conversion efficiency observed in oxide interfaces. An important factor in the SGE theory is disorder which ensures the stationarity of the conversion. Through this paper, we propose a procedure for the evaluation of the SGE on disordered lattices which can also be readily implemented for multiband systems. We demonstrate the performance of the method for a single-band Rashba model and compare our results with those obtained within the self-consistent Born approximation for a continuum model.
