45th Conference of the Middle European Cooperation in Statistical Physics

Cluj panorama

6th - 8th May, 2020 - Cluj-Napoca (Kolozsvár, Klausenburg), Romania

!!! Important  !!!

In regard to the spread of the COVID-19 and the travel restrictions that are now implemented in most parts of the world, we would like to inform you that the organization committee of the MECO45 conference has decided to take the following actions:

For the moment, we are suspending all arrangements for the MECO45 conference, and we will take a final decision on how to proceed on 15th of April 2020. We are optimist about the improvement of the situation in the course of a month, and hope that the conference can be organized as planned. Also, we are taking into account the possibility of rescheduling the conference to a later date. If the conference is cancelled/rescheduled and you have booked airplane tickets and hotels that cannot be reimbursed, we would be happy to have you here for a smaller friendly meeting and visit (if international travel is allowed).

We will keep you informed by email and through the conference website about further developments.

Thank you for your understanding.


The conference is the 45th in a series of meetings of scientists working in the domain of Statistical Mechanics and Condensed Matter Physics.

The Conferences of the Middle European Cooperation in Statistical Physics (MECO) were initiated in 1974 with the aim of bridging the gap between the communities of scientists from the Eastern and Western blocks of Europe, separated by the iron curtain. Since then, MECO conferences have become the yearly itinerant reference meetings for the community of scientists who are active in the field of Statistical Physics in the broader sense, including modern interdisciplinary applications to biology, finance, information theory, and quantum computation.

The 45th edition is organized by the Faculty of Physics, Babeș-Bolyai University and the Transylvanian Branch of the Hungarian Academy of Sciences (KAB)

The present conference is oriented in the direction of applications of statistical mechanics in complex systems. However, contributed talks will be selected from all areas of statistical physics, see below.

Main topics

 Disordered and frustrated systems
 Strongly correlated systems
 Soft and active matter
 Networks and complex systems
 Synchronization and collective behavior
 Quantum many body systems and quantum computation

The MECO meetings are yearly surveys for the novel results related to statistical physics. In general, contributions to these conferences have a wide spectrum ranging from the classical models and methods of statistical physics to modern interdisciplinary applications. Depending on the research specialization of the organizing institutes the meeting might focus also on a more clearly defined topic, without being restricted to other contributions. The 2020 MECO45 meeting is therefore focusing on complex systems and their methods of study that are inspired by statistical physics. Simple and complex models of statistical physics, it's analytical and/or numerical methods have proven to be helpful and successful in tackling the complexity of the world around us. The main topics covered by most of the keynote and invited talks are related to either models or methods. Besides the popular fields of complex networks, dynamical systems, emergence, econo- and socio-physics, phase-transitions and pattern formation we also expect contributions tackling other novel problems, models and methods that are not directly related to the above problems. For the present conference, we propose thus to edit the special issue in two directions, one focusing on general contributions in all the fields related to statistical physics and the other closely related to complex systems. For the second direction targeting complex systems we intend to invite also contributions from well-known researchers who will not have the opportunity to join us at the MECO 45 meeting in Cluj-Napoca. Submission of contributions to this special issue is encouraged for all participants of the MECO 45 conference.

If the reqired number of proceedings articles are submitted, after review process they will be published in a special issue of the Entropy open access journal.

Poster teasers

Upload of 1 minute video abstracts starts after acceptance (2 March, 2020).
