Atomic coherent state in Schwinger bosonic realization for optical Raman coherent effect
Hong-Yi Fan, Xue-xiang Xu, Li-yun Hu
For optical Raman coherent effect we introduce the atomic coherent state (or the angular momentum coherent state with various angular momemtum values) in Schwinger bosonic realizat…
Photon--added squeezed thermal states: statistical properties and its decoherence in a photon-loss channel
Xue-xiang Xu, Li-yun Hu, Hong-yi Fan
Using the normally ordered Gaussian form of displaced-squeezed thermal field characteristic of average photon number n, we introduce the photon-added squeezed thermo state (PASTS)…
Entropy-variation with respect to the resistance in quantized RLC circuit derived by generalized Hellmann-Feynman theorem
Hong-yi Fan, Xue-xiang Xu, Li-yun Hu
By virtue of the generalized Hellmann-Feynman theorem for ensemble average, we obtain internal energy and average energy consumed by the resistance R in a quantized RLC electric ci…
New application of Dirac's representation: N-mode squeezing enhanced operator and squeezed state
Xue-xiang Xu, Li-yun Hu, Hong-yi Fan
It is known that exp[i\lamda(Q_1P_1-i/2)] is a unitary single-mode squeezing operator, where Q_1,P_1 are the coordinate and momentum operators, respectively. In this paper we emplo…
