This lecture explores the thermodynamics of Bose condensation in nonequilibrium quantum gases, examining how quantum gases behave under conditions away from equilibrium. Delve into the fundamental principles governing Bose-Einstein condensation phenomena and their thermodynamic properties when subjected to nonequilibrium conditions. Learn about the complex interplay between quantum statistics, phase transitions, and energy distribution in these systems through theoretical frameworks and experimental observations presented by researchers from the Instituto de Física Interdisciplinar y Sistemas Complejos (IFISC).
