New generalized binomial theorems involving two-variable Hermite polynomials via quantum optics approach and their applications
XG Meng, JM Liu, JS Wang, HY Fan - The European Physical Journal D, 2019 - Springer
We extend the ordinary binomial theorem to the case which involves two-variable Hermite
polynomials in the context of quantum optics, and analytically obtain several new …

Time evolution of angular momentum coherent state derived by virtue of entangled state representation and a new binomial theorem
JS Wang, XG Meng, HY Fan - Chinese Physics B, 2019 - ui.adsabs.harvard.edu
We study how can an angular momentum coherent state| tau> le∣ τ> keeps its form-
invariant during time evolution governed by the Hamiltonian H= f (t){J} _ {+}+{f}({*)}(t){J} …

Negativity of Wigner function and phase sensitivity of an SU (1, 1) interferometer
CL Liu, LL Guo, ZM Zhang, YF Yu - Chinese Physics B, 2019 - iopscience.iop.org
Both the negativity of Wigner function and the phase sensitivity of an SU (1, 1) interferometer
are investigated in this paper. In the case that the even coherent state and squeezed …
