The Glauber-Sudarshan and Kirkwood-Rihaczec functions
H. M. Moya-Cessa
It is shown how to write the Kirkwood-Rihaczec quasiprobability distribution as an expectation value of the vacuum state. We do this, by writing the position eigenstates as a "disp…
Jacobi photonic lattices and their SUSY partners
A. Zúñiga-Segundo, B. M. Rodríguez-Lara, David J. Fernández C. +1
We present a classical analog of quantum optical deformed oscillators in arrays of waveguides. The normal modes of these one-dimensional photonic crystals are given in terms of Jac…
A squeeze-like operator approach to position-dependent mass in quantum mechanics
Héctor M. Moya-Cessa, Francisco Soto-Eguibar, Demetrios N. Christodoulides
We provide a squeeze-like transformation that allows one to remove a position dependent mass from the Hamiltonian. Methods to solve the Schrödinger equation may then be applied to…
Relation between the autocorrelation and Wigner functions
Héctor Manuel Moya-Cessa, Demetrios N. Christodoulides
We show a simple mechanism to measure the Wigner function of a harmonic oscillator. For this system we also show that autocorrelation and Wigner functions are equivalent.
M00N states in ion-laser interactions
A. Zúñiga-Segundo, R. Juárez-Amaro, F. Soto-Eguibar +1
A new class of entangled states, similar to N00N states is introduced. We call these states M00N states as the excitations shared in both subsystems do not need to be equal. The ge…
Position eigenstates via application of an operator on the vacuum
Héctor Manuel Moya-Cessa, Francisco Soto Eguibar
The squeezed states are states of minimum uncertainty, but unlike the coherent states, in which the uncertainty in the position and the momentum are the same, these allow to reduce…
