A Classical and Spinorial Description of the Relativistic Spinning Particle
Trevor Rempel, Laurent Freidel
In a previous work we showed that spin can be envisioned as living in a phase space that is dual to the standard phase space of position and momentum. In this work we demonstrate t…
Gravity Degrees of Freedom on a Null Surface
Florian Hopfmüller, Laurent Freidel
A canonical analysis for general relativity is performed on a null surface without fixing the diffeomorphism gauge, and the canonical pairs of configuration and momentum variables…
The loop gravity string
Laurent Freidel, Alejandro Perez, Daniele Pranzetti
In this work we study canonical gravity in finite regions for which we introduce a generalisation of the Gibbons-Hawking boundary term including the Immirzi parameter. We study the…
A Bilocal Model for the Relativistic Spinning Particle
Trevor Rempel, Laurent Freidel
In this work we show that a relativistic spinning particle can be described at the classical and the quantum level as being composed of two physical constituents which are entangle…
Quantum Spaces are Modular
Laurent Freidel, Robert G. Leigh, Djordje Minic
At present, our notion of space is a classical concept. Taking the point of view that quantum theory is more fundamental than classical physics, and that space should be given a pu…
Local subsystems in gauge theory and gravity
William Donnelly, Laurent Freidel
We consider the problem of defining localized subsystems in gauge theory and gravity. Such systems are associated to spacelike hypersurfaces with boundaries and provide the natural…
