Some q -Deformed Combinat orial Identities and Their Applications

Abstract

A q -deformed binomial theorem is firstly presented in this work. Some operator identities in q -deformed two-mode Fock space are derived by virtue of the q -binomial theorem. As an application of these identities, we prove a new completeness relation for the q -analogue of the single-complex-variable-state in the two-mode Fock space.

New Applications of q -Deformed Inverse Field operators

Hong-Yi Fan

We construct q -deformed displaced number state, q -deformed two-mode squeezed state and q -deformed two-mode single-complex-variable state by making use of the q -deformed inverse field operators. Their completeness relations are investigated by virtue of the technique of integration within an ordered product of operators. Some new operator identities in q -deformed Fock space are also derived.

Some New Operator Identities in Two-mode Fock Space

井思聪, 范洪义

Two-mode Fock space, as a Hilbert space spanned by two-mode occupation number state vectors, is widely used in quantum mechanics and quantum optics. In this work we derive some new operator identifies in this space which can help us to prove a completeness relation in the two-mode Fock space. Let a(a~+) and b(b~+) be annihilation (creation) operators of two-mode harmonic

q -Deformed Entangled States Representations and Some Applications

Ye‐Jun Xu, Jun Song, Hong‐Chun Yuan +1 more

The q-deformed entangled states are introduced by using deformation quantization methods and new normal ordering of the vacuum projection operator for q-deformed boson oscillator. In similar way, by virtue of the technique of integration within an ordered product (IWOP) of operators, the new completeness and orthogonality relations composed of the bra and ket, which are not mutually Hermitian conjugates are obtained. Furthermore, the property of squeezing operator represented by the q-deformed entangled states is exhibited. Lastly, the nonclassical properties of the q-deformed two-mode squeezed vacuum state are studied.

q-deformed binomial state

Sicong Jing, Fan Hong‐Yi

On the basis of the q-binomial theorem we construct the q-binomial state for a q-deformed boson which interpolates between the q-number state and the q-coherent state. The properties of the q-binomial state are also discussed.

DEFORMED BOSON ALGEBRA AND PROJECTION OPERATOR OF VACUUM IN NONCOMMUTATIVE PHASE SPACE

Bing-Sheng Lin, Yong Guan, Sicong Jing

In this paper we introduce a new formalism to analyze Fock space structure of noncommutative phase space (NCPS). Based on this new formalism, we derive deformed boson commutation relations and study corresponding deformed Fock space, especially its vacuum structure, which leads to get a form of the vacuum projection operator. As an example of applications of such an operator, we define two-mode coherent state in the NCPS and show its completeness relation.

Binomial theorems related to two-variable Hermite polynomials and its application in quantum optics

Fan Hong-Yi, Lou Sen‐Yue, Xiao‐Yin Pan +1 more

We propose an operator Hermite polynomial method, namely, to replace the special functions' argument by quantum mechanical operator, and in this way we have derived two binomial theorems related to two-variable Hermite polynomials. This method is concise and may be of help in deducing many operator identities, which may become a new branch in mathematical physics theory.
