**About the Editors**

**David Blaschke** obtained his PhD in theoretical physics from Rostock University in 1987 and habilitated in 1995. From 2001–2007 he was vice director of the Bogoliubov Laboratory of Theoretical Physics at the Joint Institute for Nuclear Research in Dubna. Since 2006, he has been professor at the University of Wroclaw. His works are mainly devoted to topics in quantum field theory at finite temperature, dense hadronic matter and QCD phase transitions, quark matter in heavy-ion collisions and in compact stars, as well as pair production in strong fields with applications in high-intensity lasers. He has published more than 350 articles, mostly in refereed international journals. He has obtained honorary doctorates from Dubna State University (2017) and the Russian-Armenian University in Yerevan (2019).

**Victor Braguta** obtained his PhD in theoretical physics at the Institute for High Energy Physics (Protvino) in 2004. Since then, he has worked at the Institute for High Energy Physics and, from 2011, at the Institute for Theoretical and Experimental Physics (Moscow). In 2017 he joined the Bogoliubov Laboratory of Theoretical Physics at the Joint Institute for Nuclear Research in Dubna. Now, Victor Braguta is a leading researcher at the Bogoliubov Laboratory of Theoretical Physics at the Joint Institute for Nuclear Research and a professor of MIPT. His scientific interests are quantum field theory, quantum mechanics, condensed matter physics, QCD, QCD phase diagram/phase transitions and confinement. He has published more than 100 papers on these topics.

**Evgeni Kolomeitsev** obtained his PhD in theoretical physics from Technical University Dresden in 1997. Since then, he has worked at the GSI in Darmstadt, ECT\* in Trento, Niels Bohr Institute in Copenhagen and the University of Minnesota in Minneapolis. Since 2008, he has been an assistant professor at Matej Bel University in Banska Bystrica (Slovakia) and in 2017 he joined the Bogoliubov Laboratory of Theoretical Physics at the Joint Institute for Nuclear Research in Dubna. His works are mainly devoted to physics of hadronic resonances in vacuum and in nuclear matter, nuclear equations of state, particle production in heavy-ion collisions and properties of compact stars. He has published more than 70 articles, most of them in peer-reviewed international journals.

**Sergei N. Nedelko** obtained his PhD in theoretical physics from the Bogoliubov Laboratory of Theoretical Physics at the Joint Institute for Nuclear research in 1993. In the period 1999–2001 he was a researcher at the Friedrich-Alexander Universitat Erlangen-N ¨ urnberg. From 2007–2016 he was ¨ scientific secretary of the Bogoliubov Laboratory of Theoretical Physics. At present, he is head of the research group on hadron matter physics at BLTP JINR. His work is devoted to the non-perturbative methods in quantum field theory and development of the mean field approach to QCD vacuum, quark confinement and hadronization.

**Alexandra Friesen** obtained her PhD in theoretical physics from the Bogoliubov Laboratory of Theoretical Physics at the Joint Institute for Nuclear Research in 2016. Since then, she has worked as a scientific researcher in this laboratory. Her scientific interests are centered around topics in quantum field theory at finite temperature, dense hadronic matter, QCD phase transitions and quark matter in heavy-ion collisions. She has published more than 20 articles in peer-reviewed journals. She has been awarded scholarships for young scientists and specialists named after D.I. Blokhintsev (2015, 2016) and L.D. Soloviev (2017).

**Vladimir E. Voronin** obtained his PhD in theoretical physics from the Bogoliubov Laboratory of Theoretical Physics at the Joint Institute for Nuclear Research in 2017. Since then, he has been working in this laboratory as a scientific researcher. His fields of interest include nonperturbative aspects of QCD such as confinement, chiral symmetry breaking and hadronization.
