Head of the Department of Theoretical and Computer Physics named after AV Svidzinsky, Candidate of Physical and Mathematical Sciences, Associate Professor
The history of the department begins in 1993, when the Lutsk Pedagogical Institute named after Lesya Ukrainka was established Volyn State University named after Lesya Ukrainka. An outstanding physicist-theorist, Professor Anatoliy Vadimovich Svidzinsky, was invited to head the newly established university. One of his first steps as rector was to establish the Department of Theoretical Physics and Astronomy.
From 1993 to 1995 the department was headed by Associate Professor Oleh Eduardovych Khomutenko, a student of Anatoliy Vadymovych invited from Dubna.
From 1995 to 2019, the department was headed by Professor Anatoliy Vadimovich Svidzinsky .
In 1998 the department was renamed the Department of Theoretical and Mathematical Physics.
In honor of the memory of the founder of the department and its long-term head by order of the rector, the department became the first named department at the university and is now called the Department of Theoretical and Computer Physics named after AV Svidzinsky.
Since 2019, the department is headed by Candidate of Physical and Mathematical Sciences, Associate Professor Vasyl Yevhenovych Sakhnyuk
Research work of the department is carried out in the field of low-temperature superconductivity and superfluidity, the theory of gravitation, relaxation optics and polymetric analysis. In particular, the tunneling dynamics of the Josephson effect in Bose and Fermi systems with spontaneously broken symmetry and the influence of Bose-Einstein condensate on the kinetics of supercondensate atoms in atomic Bose gases are studied. Theoretical substantiation of a number of new experimental results is performed: propagation of waves of the first and second sound in condensed Bose gas, tunneling of condensates through a potential barrier, etc. The effects of phase coherence in spatially inhomogeneous superconducting structures are investigated. The properties of the contacts of superconductors separated by a layer of dielectric, normal metal and their combinations, microstructures such as constriction, nanostructures, etc. are studied.
