Current Research and Future Direction

  • It has been recently shown that large systems in thermal equlibrium can be in entangled states even for large temperatures. I am interested in how entanglement, which is one of the most fundemental properties of quantum objects, can affect thermodynamic properties of such systems (magnetic susceptibility, heat capacity etc.).

  • I currently investigate a connection between entanglement and phase transitions (Bose-Einstein condensation, quantum phase transitions etc.).

  • I am also interested how to detect and quantify entanglement in quantum systems where the effects of Bose-Einstein and Fermi-Dirac statistics cannot be neglected (entanglement in Fock space).
