The Husimi Distribution: Development and Applications

Husimi Distribution and the Fisher Information

“…Details about the formulation of coherent states and the obtaining of Husimi distribution from these can be found on our chapter that it can be read in Ref. [13]. The main propose of this chapter is to present to the reader interesting problems in physics, such as, the harmonics oscillator [5], the Landau diamagnetism model [8,14] and, the rigid rotator [7,15], analyzed from a point of view of the information measures.…”

“…For our purpose we will use a complete description of the Husimi Distributionin three dimensions in order to study such system, so as it was shown in our previous contributions (see Ref. [13], where we have discussed some limiting cases as high and low temperatures. From the present analysis, when three dimensions are considered, naturally arises a lower temperature bound, whereby it is not possible to work in all finite temperatures.…”

“…[13] we research about a special semi-classical measure, the Wehrl entropy, as an important application of the Husimi distribution. In the present study we analyze some consequences of obtaining the Husimi distribution; for instance, the Fisher information for fundamental problems in physics for which the coherent states formulation is well defined.…”
