Thermodynamical properties of a model quon gas are reported. The quons considered are the objects obeying the deformed commutatoraa†−qa†a=1with−1⩽q⩽1.Althoughq=1andq=−1correspond respectively to boson and fermion statistics, it is not trivial to generate a quon gas which interpolates between the boson gas and the fermion gas without Pauli’s exclusion principle. The proposed model, interpolating between the two limits, can realize the Maxwell-Boltzmann limit atq=0and simulate a free anyon gas. Under the restriction−1⩽q⩽1,the gas is deformed but bosonic in nature. It shows the Bose-Einstein condensation even in two dimensions. ©2000 American Institute of Physics.
