APPROXIMATE CANONICAL QUANTIZATION FOR COSMOLOGICAL MODELS [PDF]

open access: yesInternational Journal of Modern Physics D, 1999
In cosmology minisuperspace models are described by nonlinear time-reparametrization invariant systems with a finite number of degrees of freedom. Often these models are not explicitly integrable and cannot be quantized exactly. Having this in mind, we present a scheme for the (approximate) quantization of perturbed, nonintegrable, time ...

Canonical Quantization of the Dissipative Hofstadter Model [PDF]

open access: yesNew Physics: Sae Mulli, 2015
We perform canonical quantization of the dissipative Hofstadter model, which has a wide range of applications in condensed matter physics and string theory. The target space duality and the non-commutative algebra developed in string theory are discussed for the model. We show that the target space duality transformation of closed string theory, $O(2,2;

Wigner Quantization of Hamiltonians Describing Harmonic Oscillators Coupled by a General Interaction Matrix

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
In a system of coupled harmonic oscillators, the interaction can be represented by a real, symmetric and positive definite interaction matrix. The quantization of a Hamiltonian describing such a system has been done in the canonical case.
