A new interacting Fock space, the Quon algebra with operator parameter and its Wick's theorem

Motivated by the creation-annihilation operators in a newly defined interacting Fock space, we initiate the introduction and the study of the Quon algebra. This algebra serves as an extension of the conventional quon algebra, where the traditional constant parameter $q$ found in the $q$–commutation relation is replaced by a specific operator. Importantly, our investigation aims to establish Wick’s theorem in the Quon algebra, offering valuable insights into its properties and applications.
