Short presentation

In my work, I use a combination of first-principles methods and coarse-grain models to study different materials' classes. My work includes applications of computational methods to calculate properties of existing materials and analyze underlying principles, and to design novel materials. My current focus is on Heusler alloys as potential permanent magnets.

Keywords: density functional theory computational materials science magnetic heusler alloys electrocaloric effect

  • Application of density functional theory to study structural, magnetic and electronic properties of metallic surface alloys and interfaces, magnetic properties of Heusler alloys, as well as properties of ferroelectric materials.
  • Monte Carlo simulations of Heisenberg model to study magnetic transitions.
  • Use of molecular dynamics simulations for a coarse-grain effective Hamiltonian to calculate finite temperature properties, e.g., calculation of temperature-strain phase diagram for epitaxially strained oxide and impact of domain walls on transitions.
  • Study of the electrocaloric effect focusing on the comparison between the direct and indirect methods, and understanding the anisotropy of the effect as well as tuning the temperature change by applying strain.
