Variational principle for gravity in the extended phase space
Pankaj Sharan
Variational formalism in the extended phase space for fields is applied to gravity. It is shown that the requirement of invariance under arbitrary local inertial frames implies a c…
Covariant Extended Phase Space for Fields on Curved Background
Pankaj Sharan
It is shown that the nature of physical time requires the extended phase-space in mechanics to have a bundle structure with time as the 1-dimensional base manifold and the phase sp…
On Minimum Uncertainty States
Pankaj Sharan
Necessary and sufficient condition for the existence of a minimum uncertainty state for an arbitrary pair of observables is given.
Poincare Cartan Form for Gauge Fields in Curved Background
Pankaj Sharan
The `directly Hamiltonian' field theory in the extended phase space is applied to gauge fields in curved spacetime background. These fields being differential 1-forms, have canonic…
Poincare-Cartan form for scalar fields in curved background
Pankaj Sharan
Poincare-Cartan form for scalar field is constructed as a differential 4-form in a `directly Hamiltonian' formalism which does not use a Lagrangian. The canonical momentum of a…
Causality and Peierls Bracket in Classical Mechanics
Pankaj Sharan
Relation between the Peierls and the Poisson bracket is derived in classical mechanics of time-dependent systems. Equal-time Peierls brackets are seen to be the same as the Poisson…
