Fluctuations of a q -deformed fermion gas
Qi-Jun Zeng, Jing Ge, Yongsong Luo
Abstract The theory of q -deformed fermions is one of the theories of q -deformed oscillators. Within the framework of this theory and the traditional fluctuation theory, we investigate fluctuations of q -deformed fermion gas and obtain the expressions of fluctuations of the internal energy U , the particle number N and the correlation of fluctuations of the two physical quantities above. Further numerical calculation reveals that fluctuations of such a system have some interesting and particular features. We consider that this work may provide much insight into the theory of q fermions, and may also be helpful for the theory of q -deformed oscillators.
