Purification Hamiltonians
Jorge A. Anaya-Contreras, Arturo Zúñiga-Segundo, Héctor M. Moya-Cessa
We study the Jaynes-Cummings interaction when initial mixed states, for the atom or the field, are considered. The evolved mixed field density matrix is purified to a wavefunction…
Quasiprobability distribution functions from fractional Fourier transforms
Jorge A. Anaya-Contreras, A. Zúñiga-Segundo, Héctor M. Moya-Cessa
We show, in a formal way, how a class of complex quasiprobability distribution functions may be introduced by using the fractional Fourier transform. This leads to the Fresnel tran…
Squeeze operators in classical scenarios
Jorge A. Anaya-Contreras, Arturo Zúñiga-Segundo, Francisco Soto-Eguibar +2
We analyse the paraxial field propagation in the realm of classical optics, showing that it can be written as the action of the fractional Fourier transform, followed by the squeez…
