Half Quantization
A general dynamical system composed by two coupled sectors is considered. The initial time configuration of one of these sectors is described by a set of classical data while the other is described by standard quantum data. These dynamical systems will be named half quantum. The aim of this paper is to derive the dynamical evolution of a general half quantum system from its full quantum formula...
متن کاملQuantum Half-Planes via Deformation Quantization
We give an idea of constructing irreducible unitary representations of Lie groups by using Fedosov deformation quantization in the concrete case of the group Aff(R) of affine transformations of the real line. By an exact computation of the star-product and the operator ˆ̀Z , we show that the resulting representations exhausted all the irreducible representations of this groups.
متن کاملImage reconstruction using Half tone and Kekre’s Fast Codebook Generation Vector Quantization technique
Now a day’s transmission of image and video data is gradually increasing. Compression of image data with acceptable image quality is the objective of this paper. To achieve higher Compression Ratio combination of halftone and Kekre’s Fast Codebook Generation (KFCG) Vector Quantization algorithm is used. For Vector Quantization KFCG algorithm is used to reduce time and memory space. Half toning ...
متن کاملThere are many ways to spin a photon: Half-quantization of a total optical angular momentum
The angular momentum of light plays an important role in many areas, from optical trapping to quantum information. In the usual three-dimensional setting, the angular momentum quantum numbers of the photon are integers, in units of the Planck constant ħ. We show that, in reduced dimensions, photons can have a half-integer total angular momentum. We identify a new form of total angular momentum,...
متن کاملOn the Γ-equivariant Form of the Berezin's Quantization of the Upper Half Plane
Introduction Let Γ be a fuchsian subgroup of P SL(2, R). In this paper we consider the Γ-equivariant form of the Berezin's quantization of the upper half plane which will correspond to a deformation quantization of the (singular) space H/Γ. Our main result is that the von Neumann algebra associated to the Γ− equivariant form of the quantization is stable isomorphic with the von Neumann algebra ...
