Alternative Canonical Formalism for the Wess-Zumino-Witten Model
S. G. Rajeev, G. Sparano, P. Vitale
We study a canonical quantization of the Wess--Zumino--Witten (WZW) model which depends on two integer parameters rather than one. The usual theory can be obtained as a contraction…
On the Zero-Slope Limit of the Compactified Closed Bosonic String
Raffaele Marotta, Franco Pezzella
In the framework of the compactified closed bosonic string theory with the extra spatial coordinates being circular with radius , we perform both the zero-slope limit and the $R…
Thermal noise and oscillations of photon distribution for squeezed and correlated light
V. V. Dodonov, O. V. Man'ko, V. I. Man'ko +1
The oscillations of photon distribution function for squeezed and correlated light are shown to decrease when the temperature increases.The influence of the squeezing parameter and…
A generalization of the Jordan-Schwinger map: classical version and its q--deformation
V. I. Man'ko, G. Marmo, P. Vitale +1
For all three--dimensional Lie algebras the construction of generators in terms of functions on 4-dimensional real phase space is given with a realization of the Lie product in ter…
Quantum Limits in Interferometric GW Antennas in the Presence of Even and Odd coherent states
Nadeem A. Ansari, L. Di Fiore, M. A. Man'ko +3
We discuss a model for interferometric GW antennas without dissipative or active elements. It is predicted that the even and odd coherent states may play an alternative role to squ…
Multidimensional Hermite polynomials and photon distribution for polymode mixed light
V. V. Dodonov, O. V. Man'ko, V. I. Man'ko
For N-mode light described by the Wigner function of generic Gaussian form the photon distribution function is obtained explicitly and expressed in terms of Hermite polynomial of $…
Photon distribution for one mode mixed light with generic gaussian Wigner function
V. V. Dodonov, O. V. Man'ko, V. I. Man'ko
For one-mode light described by the Wigner function of generic Gaussian form the photon distribution function is obtained explicitly and expressed in terms of Hermite polynomials o…
Photon statistics of multimode even and odd coherent light
Nadeem A. Ansari, V. I. Man'ko
The even and odd coherent states are generalized for multimode case. The explicit forms for the photon distribution, Q-function and Wigner function are derived. In particular, it i…
Dynamical Aspects of Lie--Poisson Structures
F. Lizzi, G. Marmo, G. Sparano +1
Quantum Groups can be constructed by applying the quantization by deformation procedure to Lie groups endowed with a suitable Poisson bracket. Here we try to develop an understandi…
Generalized Reduction Procedure: Symplectic and Poisson Formalism
J. Grabowski, G. Landi, G. Marmo +1
We present a generalized reduction procedure which encompasses the one based on the momentum map and the projection method. By using the duality between manifolds and ring of funct…
Current Algebra and Conformal Field Theory on a Figure Eight
A. P. Balachandran, G. Bimonte, K. S. Gupta +4
We examine the dynamics of a free massless scalar field on a figure eight network. Upon requiring the scalar field to have a well defined value at the junction of the network, it i…
Correlation functions of quantum q-oscillators
V. I. Man'ko, G. Marmo, S. Solimeno +1
Nonlinearity of electromagnetic field vibrations described by q-oscillators is shown to produce essential dependence of second correlation functions on intensity and deformation of…
Finite-Temperature Scalar Field Theory in Static de Sitter Space
D. V. Fursaev, G. Miele
The finite-temperature one-loop effective potential for a scalar field in the static de Sitter space-time is obtained. Within this framework, by using zeta-function regularization,…
