Our Works
Our research focuses on several directions, which are overlapping in interesting ways:
Physics of quantum technologies (quantum optics, metrology, information, measurements, quantum thermodynamics).
Decision theory (games, bargaining, opinion dynamics, entropy, utility, econophysics).
Probabilistic inference (maximum likelihood, maximum entropy, causality).
Statistical physics, thermodynamics and complex systems (non-equilibrium, magnetic field, adaptive systems, hydrodynamics).
