Dear Colleagues,
During the last three decades, the study of quantum phase transitions (QPTs) has been under continuous development, growing into a mature and well-established field. Identified as sudden changes in the ground-state properties of quantum systems as their parameters change, QPTs occur in a wide range of different setups, from atomic physics, quantum optics, and condensed matter to quantum information and cosmology. Consequently, their research has contributed to establishing connections across several fields of physics and unraveling new features in both few- and many-body quantum problems.
Thanks to the progress in new experimental, theoretical, and numerical tools, the concept of QPT has recently been extended to other domains, including excited states and nonequilibrium setups, where the understanding of critical phenomena such as excited-state quantum phase transitions (ESQPT) and dynamical phase transitions (DQPT) still poses challenges. Unquestionably, the field is fruitful, and several questions remain open about the relationship between quantum critical phenomena and several topics such as chaos, entanglement, localization, transport, thermal and informational effects, finite-size effects, out-of-equilibrium processes, and their role in the quantum-classical correspondence, among several others.
In this second volume of the Special Issue, we continue to review recent trends in the study of quantum phase transitions, covering but not restricted to the following areas:
*) Quantum phase transitions in novel systems;
*) Mean field and many-body techniques applied to the study of quantum phase transitions;
*) Excited-state quantum phase transitions (ESQPTs);
*) Nonequilibrium effects and dynamical quantum phase transitions (DPTs);
*) Transport and dynamic properties in the quantum critical region;
*) Chaos, localization, and quantum criticality;
*) Universality and quantum criticality.

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 submissions that pass pre-check are 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. Entropy 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 2600 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.
