A diagonal representation of the quantum density matrix using q-boson oscillator coherent states
Abstract:
A q-analogue of Sudarshan's diagonal representation of the quantum mechanical density matrix is obtained using q-boson coherent states. Earlier result of Mehta and Sudarshan on the self reproducing property of r(z¢,z) is also generalized and a self-consistent self-reproducing kernel $\bar{K}(z',z)$ is constructed.
