Abstract

In this work, we present a general approach for deriving the normal product form of multi-mode boson exponential quadratic operators from the viewpoint of linear quantum transformations in boson Fock space. The simplicity and generality of our formula are shown by some examples.

Linear Quantum Transformation Theory of Multi-Mode Bosons and Its Application to Calculation of Partition Function

Sixia Yu, Yong-De Zhang

In this paper, we present a linear quantum transformation theory in the -mode boson Fock space, and give a formula that shows how a transformation operator changes its exponential form to its normal ordered form. As an application we evaluate the partition function of a general quadratic system without any information of the energy levels of the system by using our transformation theory.

Linear Quantum Transform Theory in Bargmann–Fock Space and Its Preliminary Application

Yong-De Zhang, Zhong Feng Tang

A general theory for the linear transform in Bargmann–Fock space of n-mode boson system is presented. The group structure of transform is analyzed and the explicit expressions of transform operations in terms of normal ordering are given. As applications, a series of useful identities are given, the decoupling problem for general two-boson interaction and the normal product calculation of boson exponential quadratic operators are studied.

Analytic Calculation of Arbitrary Matrix Elements for Boson Exponential Quadratic Operators

Pan Jianwei, Hou Guang, Zhang Yongde

By means of the transformation relation between the ordinary form of boson exponential quadratic operators (BEQO) and its anti-normal product form, we present an effective method to conveniently calculate arbitrary matrix elements of BEQO. By this method, many important matrix elements can be calculated analytically. As a direct application, we obtain the exact solutions of the density matrix and partition function for general boson quadratic Hamiltonian without any information about the energy level.

Some Addenda About the General Formula of Normal Product Calculation for Boson Exponential Quadratic Operators

Jian-Wei Pan, Yong-de Zhang, Xiang‐Bin Wang +1 more

In this paper, we studied the general formula of normal product calculation for boson exponential quadratic operators (EQO) which is first obtained by WANG et al. (J. Phys. A: Math. Gen. 27 (1994) 6563]. It is shown that the boundness of boson EQO will result in a restriction on the applicable bounds of this formula. According to the restriction condition, the conclusion about unity operator given by MA et al. [Commun. Theor. Phys. (Beijing,China) 21 (1994) 119] should be made some corresponding corrections. At last, we extended this formula to the case of fermion for the convenience of later applications.
