Department of theoretical physics

Founded in 1929, along with the Institute of Physics.

The first head of the department of theoretical physics (from 1929 to 1932) was the Ukrainian theoretical physicist Leon Kordysh, who at that time also headed the department of theoretical physics at the Kyiv University. L. Kordysh stood at the origins of theoretical physics in Ukraine. He was working in its various directions, in particular, on the theory of relativity and quantum theory, X-ray physics, theory of oscillations, theory of electrical conductivity, photoelectric phenomena, and radioactivity.
In 1932, the department was headed by Professor Lev Shtrum, who had been a PhD student of L. Kordysh. He worked on the problems of quantum mechanics, the theory of nuclear structure, and the special relativity theory. L. Shtrum’s life ended tragically—he was subjected to repression and executed by the Soviet regime in 1936.
After the extermination of L. Strum, it was decided that the theoretical department could be headed by the invited physicist Nathan Rosen, an American and Israeli theorist who is best known for his work "Can a quantum-mechanical description of physical reality be considered complete?" in co-authorship with A. Einstein and B. Podolsky (1935). N. Rosen headed the department of theoretical physics from 1936 to 1938.
With the departure of Rosen in 1938, the department of theoretical physics was left without supervision. During the Second World War, the Institute of Physics was evacuated, and the work of the department of theoretical physics was suspended.
After returning from evacuation, the department of theoretical physics resumed its work under the supervision of Dr. Solomon Pekar, who headed the department from 1944 to 1960. The most important results of the department under S. Pekar's supervision were the works on the theory of polarons; development of a general theory describing the shape of impurity absorption bands and luminescence caused by electron-phonon interaction; the theory of excitons. There were many well-known theoretical physicists in the department headed by S. Pekar, namely, O. Davydov, M. Deigen, I. Dykman, E. Rashba, K. Tolpygo. In 1960, the department of theoretical physics headed by S. Pekar was transferred to the Institute of Semiconductors, which had just been founded.
A new theoretical department at the Institute of Physics was organized in 1964 under the supervision of Oleksandr Davydov, a corresponding member (later academician) of the Academy of Sciences of the Ukrainian SSR. Under his supervision, the department conducted research on excitons and optical phenomena in solids, kinetic phenomena in semiconductors under the influence of an electric field, pressure, etc. In 1966, O. Davydov moved to the newly created Institute of Theoretical Physics, but he continued to manage the department of theoretical physics at the Institute of Physics on a voluntary basis for some time.
In 1973, the department of theoretical physics was handed over to Dr. Petro Tomchuk (later professor, corresponding member of the National Academy of Sciences of Ukraine). P. Tomchuk was a disciple of the prominent theoretical physicist I. Dykman. The main areas of research of the department under P. Tomchuk’s supervision comprised the physics of semiconductors, metals, liquid crystals, biological molecular structures; nanophysics; quantum optics. In particular, P. Tomchuk developed the theory of nonlinear volt-ampere characteristics, as well as the theory of electron and photon emission from island metal films during current or laser heating of electrons (State Prize in Science and Technology in 1986). He also proposed a physical model and the theory of photodiode degradation (State Prize of Ukraine in Science and Technology in 1995). In 2021, after 48 years of leadership, Prof. Tomchuk left the position of the head of department and moved to a chief researcher’s position. The duties of the head of the department were handed over to Dr. I. Gandzha. Employees of the department are currently working on the departmental project "Kinetic and wave processes in nonlinear, non-equilibrium and low-dimensional systems."

Most important results in the history of the department

  • 2018–2023 An hierarchy of generalised nonlinear Schrödinger equations was derived to describe the dynamics of the envelope of slowly modulated wave packets on different time scales in the nonlinear Klein–Gordon model with arbitrary polynomial nonlinearity. Temporal scales of higher orders were demonstrated to manifest themselves in a slow modulation of the constant amplitude of envelope solitons and lead to the formation of quasisolitons that propagate with almost constant velocity and pertain almost steady form during long time intervals. (Gandzha I.S., Sedletsky Yu.V.)
  • 2018–2019 An explanation for the self-organisation of spherical colloids into various chains and clusters was provided. A new theory of strong enhancement of the optical torque on the director in dye doped nematics was constructed.

Irregular wave patterns with intricate surface profiles were calculated. (Gandzha I.S., Lukomsky V.P.)

Theory of absorption of ultrashort laser pulses by elliptic-like metal nanoparticles. (Tomchuk P.M., Grigorchuk M.I. [Institute for Theoretical Physics])
  • 1995–2009 Mathematical models of physical processes in biological systems of spatial orientation and gravireception: computer 3D model of the otholite membrane, model of the dynamics of semicircular channels, model of the interaction of receptor cells with the surrounding gel. (Kondrachuk A.V.)
