Special Issue Information

Dear Colleagues,

This Special Issue will publish selected papers from the Quantum Complex Matter (QCM) 2020 conference, in joint collaboration with the QCM school, on 8–12 June 2020 in Frascati, Italy. You are warmly invited to contribute an article/review paper for possible publication in our Special Issue. Submissions will be rapidly reviewed and published shortly, if accepted.

This international conference, in joint collaboration with the Quantum Complex Matter school (QCM2020, 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 based on the Frontiers of Condensed Matter Physics (FCMP) lecture courses and selected topics from the Superstripes conferences. Submissions should focus on the following research subfields:

Correlated electronic systems:

Unconventional superconductivity;

Novel magnetism;

Mott transition;

Quantum criticality;

Multi-band Hubbard model;

Lifshitz transitions.


Nano science:





2D materials;

Fano resonances.



Itinerant electron;


Spin current;

magnetic memory.

Cold atoms:

Feshbach resonance;

Hubbard model

BEC-BCS crossover.

This Special Issue also welcomes regular submissions from researchers who will not be able to participate in the conference. Your contribution will help this Special Issue to provide additional value to the research community.

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) for publication in this open access journal is 1000 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.

Ostwald Growth Rate in Controlled Covid-19 Epidemic Spreading as in Arrested Growth in Quantum Complex Matter

Here, we focus on the data analysis of the growth of epidemic spread of Covid-19 in countries where different policies of containment were activated. It is known that the growth of pandemic spread at its threshold is exponential, but it is not known how to quantify the success of different containment policies. We identify that a successful approach gives an arrested phase regime following the Ostwald growth, where, over the course of time, one phase transforms into another metastable phase with a similar free energy as observed in oxygen interstitial diffusion in quantum complex matter and in crystallization of proteins. We introduce the s factor which provides a quantitative measure of the efficiency and speed of the adopted containment policy, which is very helpful not only to monitor the Covid-19 pandemic spread but also for other countries to choose the best containment policy. The results show that a policy based on joint confinement, targeted tests, and tracking positive cases is the most rapid pandemic containment policy; in fact, we found values of 9, 5, and 31 for the success s factor for China, South Korea, and Italy, respectively, where the lowest s factor indicates the best containment policy.
