The main tasks of ICMP of National Academy of Sciences of Ukraine is carrying out fundamental research in theoretical physics and condensed matter physics, and performing other research in physics, chemistry, mathematics, information and computer technology, ecology, preparation of highly qualified specialists, spreading results of research etc.


In memory of Dr. Ralph Kenna

It is with deep sadness that we inform you that on October 26, 2023, at the sixties year of his life, Ralph Kenna - a professor at Coventry University, an honorary doctor of our institute, a talented scientist, a friend of Ukraine , a kind and bright person - passed away. We express our sincere condolences to his family and to everyone who knew him. May he rest in peace.

The XVIII Annual Meeting of the Scientific Council “Physics of Soft Matter”

The  XVIII Annual Meeting of the Scientific Council “Physics of Soft Matter” will be held on November 1 - 3, 2023 in Lviv in the premises of the Institute of Condensed Matter Physics of the National Academy of Sciences of Ukraine (Sventsitskii Street, 1, Conference Hall).
Like all the previous ones, this year's meeting will focus on the discussion of current fundamental and applied problems of the physics of soft matter. Special emphasis will be placed on topics from the field of scientific interests of Prof. Myroslav Holovko, who is celebrating his 80th birthday these days. During the meeting, scientific reports and issues related to the coordination of research within the scope of the Scientific Council will be discussed.
The Programme of Annual Meeting is presentedhere.

Grand partition function functional for simple fluids

I.R. Yukhnovskii
R.V. Romanik

In this paper, we will systematically present the method of collective variables with a reference system for a classical many-particle interacting system in the grand canonical ensemble. The emphasis will be placed on the details of calculations. In particular, the usage of total correlation functions defined for the grand canonical ensemble allows us to investigate very accurately the cumulants of the grand partition function for the reference system. It is shown that any cumulant Mn can be expressed as a product of three components: the average particle number within the reference system, a Kronecker’s symbol for n wave vectors, and the n-particle structure factor. The functional expression for the grand partition function is derived, with all coefficients explicitly defined. The coordinates of the critical point are computed in the mean field approximation.


Round table "Frontiers in Science: Hot topics in research, management, and financing"

Institute for Condensed Matter Physics initiates a one-day round table "Frontiers in Science: Hot topics in research, management, and financing", covering both scientific and other aspects of the research activity. We would like to present a "bird's view" on a current state of scientific research in general, including broad fields and the multidisciplinary context.
The pleasant occasion for this event is 60th birthday of Prof. Jaroslav Ilnytskyi, the head of dept. of Computer Simulations of Many-particle Sysyems.
The round table will take place on 10 October (Tuesday), 10:30-17:00 (Ukrainian time) in a mixed format: live + online. The working language is English.
