A transformational property of the Husimi function and its relation to the Wigner function and symplectic tomograms
(Theoretical and Mathematical Physics, 2011)
We consider the Husimi Q-functions, which are quantum quasiprobability distributions in the phase space, and investigate their transformation properties under a scale transformation (q, p) - gt (lambda q, lambda p). We ...
Operator method for calculating q symbols and their relation to weyl-wigner symbols and symplectic tomogram symbols
(Maik Nauka Publishing / Springer SBM, 2014)
We propose a new method for calculating Husimi symbols of operators. In contrast to the standard method, it does not require using the anti-normal-ordering procedure. According to this method, the coordinate and momentum ...
Scale transformations in phase space and stretched states of a harmonic oscillator
(Maik Nauka Publishing / Springer SBM, 2017)
We consider scale transformations (q, p) - gt (lambda q, lambda p) in phase space. They induce transformations of the Husimi functions H(q, p) defined in this space. We consider the Husimi functions for states that are ...
