The Glauber-Sudarshan and Kirkwood-Rihaczec functions (1311.5598v1)
Published 21 Nov 2013 in quant-ph
Abstract: 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 "displacment" of the vacumm. We also give a relation between the Glauber-Sudarshan and Kirkwood-Rihaczec quasiprobability distributions.
