Squeezing State of Anti-ferromagnetic Raman Scattering
LV Xiu-juan · Journal of Qufu Normal University · 2005
Many non-classical states have been found in the field of quantum mechanics, among which is the squeezing state. In general, according to the requirements of the uncertainty principle, a squeezed state may have lower quantum fluctuation in one quadrature than that in a coherent state, while another quadrature is greater than that of a coherent state. The idea of the squeezing states can be used to reduce quantum noise in measuring high precise signal. In this paper, the authors discussed the effect of temperature on the quantum fluctuations in the second-order Raman scattering. The domain of temperature is obtained, which satisfies the conditions of generating squeezed states.
