Glauber-Sudarshan P-Representation
From Wikipedia, the free encyclopedia
The Glauber-Sudarshan P-Representation is a way of writing down the state of any type of light using the coherent states as a basis. It was developed by George Sudarshan and later adopted by Roy J. Glauber (see the references below). It was the subject of a controversy when Glauber was awarded a share of the 2005 Nobel Prize in Physics for his work in this field and Sudarshan's contribution was not recognized.
In this representation, the density matrix is written as:
,
where 
are the coherent states and 
is a quasi-probability distribution.
