Real Time Propagator in the First Quantised Formalism
Samir D. Mathur
We argue that a basic modification must be made to the first quantised formalism of string theory if the physics of `particle creation' is to be correctly described. The analogous…
Information Retrieval from a Charge `Trap'
Samir D. Mathur
We study the model of massless electrodynamics with nonconstant coupling, introduced by Peet, Susskind and Thorlacius as the `charge hole'. But we take the boundary of the st…
Is the Polyakov path integral prescription too restrictive?
Samir D. Mathur
In the first quantised description of strings, we integrate over target space co-ordinates and world sheet metrics . Such path integrals give scattering amplitudes be…
Kinetic theory in curved space: a first quantised approach
Samir D. Mathur
We study the real time formalism of non-equilibrium many-body theory, in a first quantised language. We argue that on quantising the relativistic scalar particle in spacetime with…
