Research Interests

  • Magnetic Lanthanides: Simulation of Feshbach resonances of ultra cold collisions of erbium and dysprosium.​
  • Ultracold Chemical Reactions: Computation of potential energy surfaces of few-atom molecules and the reactivity in ultracold atom-dimer collisions. Control of Ultracold Chemical Reactions Through Conical Intersection.
  • Controlling Polar Molecules: Trapping conditions for ultracold polar molecules by laser beams when static electric and magnetic fields are applied.
  • Atom-Ion Charge-Exchange Reactions: We study atom-ion charge-exchange reactions induced by an external laser field using a dressed-molecule approach. We develop theoretical and practical models of efficient sympathetic cooling of molecules by collisions  with laser-cooled and highly-polarizable atoms
