The effects of nonextensivity characterized by a parameter are explored by calculating the temperature dependent thermodynamic properties, fraction of condensed particles, and density distributions of condensed and thermal components of the system. It is found that nonextensivity in the underlying statistical mechanics may have large effects on the BEC transition temperature.EnglishApproximation theoryCondensationElectron energy levelsEntropyGas dynamicsKinetic energyPhase transitionsPhononsQuantum theoryRelaxation processesThermodynamicsInternal energyQuantum systemsS-wave scatteringTwo-dimensional systemsStatistical mechanicsTrapped interacting Bose gas in nonextensive statistical mechanicsArticle10.1103/PhysRevE.65.046105
