Research interests

The following examples show a few details, more can be found in the papers linked in the publication list.

Structural phase transition in crystalline FeO under pressure

[figure: FeO phase diagram]

Pressure–volume equation of state of crystalline iron oxide calculated using diffusion quantum Monte Carlo method (lines), Phys. Rev. Lett. 101, 185502 (2008). (In collaboration with Lubos Mitas, NCSU.)

Legend: rock salt (B1) structure stable at low pressures (red line), NiAs (iB8) structure stable at high pressures (blue line), B1 experimental data (circles), iB8 experimental data (squares). Diffusion Monte Carlo predicts the transition pressure Pc at approximately 65 GPa, providing substantial improvement compared to DFT based approaches.

Mean-field phase diagram for non-interacting disordered electrons

[figure: disorder phase diagram]

Phase diagram for an impure crystal calculated from our proposal of a mean field theory for disordered electronic systems, Phys. Rev. B 71, 033103 (2005), ibid. 245106 (2005). (In collaboration with Vaclav Janis, FZU AV CR.)

Legend: energy of quantum state (x-axis), measure of disorder strength (y-axis), band edge (black line), mobility edge (red line), localized/non-diffusive states (hatched area), extended/transport states (white “egg”)

Teaching

Exercises that accompany undergraduate course of Thermodynamics and Statistical Physics (Faculty of Mathematics and Physics, Charles University, Prague) – somewhat outdated (I was doing this in years 2002–2005), but might not be completely useless if you understand Czech.
