Special Issue Information

Dear Colleagues,

At low temperatures, the kinetic energy per particle in a quantum crystal is much larger than kBT (where kB represents the Boltzmann constant and T the temperature) and the spatial fluctuations of the atoms around their equilibrium lattice positions are up to ~10% of the distance to the neighboring lattice sites. These intriguing qualities can be understood only in terms of quantum mechanical arguments.

The study of quantum crystals is very important to understand nature. Hydrogen and helium, two archetypal quantum species, are the most abundant elements in the universe and thus an exhaustive knowledge of their condensed matter phases is crucial for understanding the chemical composition and past and future evolution of planetary bodies. Quantum solids are also sought after for technological applications, including high-pressure synthesis, nuclear energy, gas storage, quantum computing, and nanoelectronics.

We invite investigators to submit research papers discussing the experimental and theoretical understanding of quantum crystals. Quantum crystals include, but are not limited to, rare-gases (e.g., He and Ne), light-weight molecular crystals (e.g., H2 and CH4), light-weight covalent, ionic and metallic solids (e.g., graphite, LiH, and Li), quantum paraelectrics (e.g., SrTiO3 and KTaO3), Wigner crystals, vortex lattices, and dipole systems.

The potential topics for this Special Issue include, but are not restricted to:

-    Experimental synthesis and characterization of quantum crystals
-    Theory and simulation 
-    Crystalline defects in quantum crystals
-    Elastic and mechanical properties
-    Quantum low-dimensional systems (i.e., thin films, one-dimensional systems, and clusters)
-    Quantum solids at high-pressure conditions
-    Gas-storage and structural properties of quantum materials
-    H-bonded ferroelectrics and quantum paraelectrics

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. Crystals is an international peer-reviewed open access monthly 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 1200 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.
