Foreword

Phase transitions and critical phenomena: universality and non-universal features

This special issue of the CMP is devoted to phase transitions and critical phenomena. Several recent decades of intensive, sometimes even frantic, and fruitful activities might produce an impression that all principal work in this field has already been completed and nothing really new can be found. Of course, this is far from being true, and the aim of the present issue is to give an evidence that the field is still fertile and thankful to those who work hard on it. We hope that the readers will find this evidence in the presented papers for which we cordially thank their authors who share this aim of ours and our devotion to the subject.

A specially pleasant mission of this issue is to pay tribute to our distinguished colleague and friend Mykhailo Kozlovskii, member of the CMP Editorial Board, who has been working in the theory of phase transitions for nearly 40 years. In August 2012, Mykhailo crossed a magic line of time, called a sixty years jubilee, and thus reached the age of maturity and wisdom. With this regard, we wish him good health and many years of fruitful and joyful life among his favorite collective variables, fishing, invariably beloved family, and faithful friends. We also wish him to open new horizons and to explore further bystreets in statistical physics, to meet new friends, colleagues and followers.

Personalia

Bertrand Berche's 50th birthday

A story from scientific folklore mentions two principal types of scientists. Scientists of the first type follow a ballistic approach in their research: they go far in a chosen direction, but the area they cover is negligibly small. Scientists of the second type follow a diffusive approach: they try to look in different directions covering a broad area but they go nowhere. Fortunately, such categorizations have exceptions. Indeed, amongst our colleagues there are those who manage to go far in their studies, searching answers to different puzzles put by nature, no matter to which specific sub-field of physics these puzzles are traditionally attributed. Bertrand Berche, who this year celebrates his first jubilee is one of them. Statistical physics, conformal field theory, gauge fields in condensed matter physics, cosmology, complex networks, sociophysics, history and philosophy of physics, these are the fields in which he works.

At this point on behalf of his friends, colleagues and the community at large, it is appropriate to celebrate Bertrand Berche’s jubilee and to wish him continued success on his way.
