Reality of the Wigner Functions and Quantization

الملخص EN

Here we use the extended phase space formulation of quantum statistical mechanics proposed in an earlier work to define an extended lagrangian for Wigner's functions (WFs).

The extended action defined by this lagrangian is a function of ordinary phase space variables.

The reality condition of WFs is employed to quantize the extended action.

The energy quantization is obtained as a direct consequence of the quantized action.

The technique is applied to find the energy states of harmonic oscillator, particle in the box, and hydrogen atom as the illustrative examples.
