Special Issue Information
Dear Colleagues,
Quantum phase transitions—changes in the ground state of a material driven by tuning non-thermal parameters such as pressure, doping, or magnetic field—are central to the study of correlated quantum materials. These transitions often occur near quantum critical points (QCPs), where quantum fluctuations dominate and lead to rich emergent behavior, such as non-Fermi liquid states, unconventional superconductivity, and topologically nontrivial phases. In particular, thermodynamic signatures offer critical insights into the nature of quantum phase transitions and the scaling behavior near QCPs. This Special Issue focuses on recent theoretical and experimental advances in understanding quantum criticality and phase transitions in strongly correlated and frustrated materials. Particular attention will be given to quantum spin liquid materials, where frustration and entanglement give rise to exotic ground states, as well as heavy fermion systems, low-dimensional magnets, and transition-metal-based compounds. We invite contributions that explore the interplay between quantum fluctuations and competing electronic or magnetic orders, the role of dimensionality, and novel measurement techniques under extreme conditions (e.g., ultra-low temperatures, high fields, or high pressures).

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.
