Hi. This webpage is devoted to my academic activities. I am a physicist, doctoral student at Faculty of Nuclear Sciences at CTU in Prague, and associate at Nuclear physics instutute at CAS in Rez. You can always contact me at ruzicka@ujf.cas.cz.

My teaching activities (in czech):

  • Winter 2016 - MECHcv (Newtonian mechanics)
    Zadání (i s řešením) pro první a druhou zápočtovou písemku.
  • Summer 2017 - ELMAcv (classical electromagnetism)
    Konečná tabulka prezence a výsledků. Kdo se vidí žlutě, získává zápočet. Ostatní se můžou účastnit náhradního termínu (bez bodové penalizace), a měli by ode mě obdržet mail kvůli domluvě termínu. Řešení přibude v průběhu dne.

My scientific interests:

  • foundations of quantum theory
  • PT symmetry in quantum mechanics
  • spectral theory of non-selfadjoint operators
