Field of Scientific Interest:

My scientific interests focus on the Berry phase and its topological effects in crystalline materials, particularly in metals featuring band-contact lines (nodal lines). This includes exploring the manifestations of the Berry phase in metal physics [G.P. Mikitik, Yu.V. Sharlai, Phys. Rev. Lett. (1999)] and its influence on magnetization and quantum oscillation phenomena [Phys. Rev. Lett. 93 (2004); Nature Communications (2023)]. Specific studies involve nodal lines in graphite and the Berry phase in graphene [Phys. Rev. B 73, 235112 (2006)], [Low Temperature Physics 34, 794].

I investigate the diamagnetic response of topological Dirac, Weyl, and nodal-line semimetals, including their magnetization, magnetic susceptibility, and quantum oscillations, as well as their coupling with the elastic properties of crystals, such as magnetostriction [Nature Communications 13, 3868 (2022)].

Additionally, my research addresses challenges in theoretical explanations of low-critical fields data in superconductors, employing the Eilenberger equations and study vortex penetration dynamics.

My work also encompasses the study of Fermi surfaces, band structures, Landau levels, and the g-factor.
