Lessons from discrete light-cone quantization for physics at null infinity: bosons in two dimensions

open access: yesJournal of High Energy Physics
Motivated by issues in the context of asymptotically flat spacetimes at null infinity, we discuss in the simplest example of a free massless scalar field in two dimensions several subtleties that arise when setting up the canonical formulation on a ...

On Conformally Coupled General Relativity

open access: yesEPJ Web of Conferences, 2018
A gravity model based on the conformal symmetry is presented. To specify the structure of the general coordinate transformations the Ogievetsky theorem is applied. The nonlinear symmetry realization approach is used.

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.

Quantizing a non-locally massive 2-form model

open access: yesPhysics Letters B
A non-local yet gauge-invariantly massive 2-form model is considered that leads to local and unitary dynamics upon proper gauge-fixing. Since canonical momenta cannot be defined owing to the non-locality, consistent quantization of this system warrants ...
