Special Issue Information

Dear Colleagues,

The amazing experimental control and accuracy that can be currently achieved in cold atoms give us a unique possibility to observe quantum mechanics at work with unprecedented resolution. We are now able to literally engineer quantum Hamiltonians and to shed light into fascinating physical phenomena, such as fermion pairing and superfluidity. The subtle interplay between quantum mechanics, quantum statistics, and interatomic forces frequently gives rise to puzzling and counterintuitive exciting behaviors, resulting in novel phases of matter, such as exotic superfluid phases with possible important topological properties. Moreover, the unique flexibility that is available in cold Fermi gases, where, for example, the interatomic forces can be tuned by controlling an external magnetic field, allows us to mimic the conditions that exist in some of the most mysterious systems in the universe, such as unconventional superconductors and even nuclear matter inside neutron stars. At the same time, Fermi gases can be modeled with relatively simple but still very challenging Hamiltonians, which makes these systems very promising test grounds for many-body theories and numerical simulation methods. Important strongly correlated regimes are known to exist in these systems, making simple approaches fail and calling for advanced correlated methodologies to accurately study the physical properties. In particular, in the last few years, in the petaflops era, we have witnessed an unprecedented progress in numerical methodologies, and cold atoms are an ideal environment to make robust advances in the formidable challenge of solving the fundamental equations of quantum mechanics with the aid of modern supercomputers. In this Special Issue of Atoms, we will collect some of the very important new theoretical and computational research results about fermionic quantum gases. Special emphasis will be dedicated to novel theoretical approaches and novel computational approaches. Reviews of existing important theoretical and computational methods and results will be welcome. Finally, there will be a number of studies involving the importance of cold atoms in condensed matter physics, nuclear physics, and nuclear astrophysics.

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. Atoms 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) for publication in this open access journal is 1400 CHF (Swiss Francs). 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.
