Escape from the Quantum Pigeon Conundrum
Gabor Kunstatter, Jonathan Ziprick, Victoria McNab +3
It has recently been argued in Aharonov et. al. (2016) that quantum mechanics violates the Pigeon Counting Principle (PCP) which states that if one distributes three pigeons among…
Quantum gravitational collapse as a Dirac particle on the half-line
Syed Moeez Hassan, Viqar Husain, Jonathan Ziprick
We show that the quantum dynamics of a thin spherical shell in general relativity is equivalent to the Coulomb-Dirac equation on the half line. The Hamiltonian has a one-parameter…
Polymer Quantization of a Self-Gravitating Thin Shell
Jonathan Ziprick, Jack Gegenberg, Gabor Kunstatter
We study the quantum mechanics of self-gravitating thin shell collapse by solving the polymerized Wheeler-DeWitt equation. We obtain the energy spectrum and solve the time dependen…
Linearized gravity with matter time
Masooma Ali, Viqar Husain, Shohreh Rahmati +1
We study general relativity with pressureless dust in the canonical formulation, with the dust field chosen as a matter-time gauge. The resulting theory has three physical degrees…
Linearized 3D gravity with dust
Viqar Husain, Shohreh Rahmati, Jonathan Ziprick
Three-dimensional gravity coupled to pressureless dust is a field theory with one local degree of freedom. In the canonical framework, the dust-time gauge encodes this physical deg…
Discrete Hamiltonian for General Relativity
Jonathan Ziprick, Jack Gegenberg
Beginning from the Ashtekar formulation of canonical general relativity, we derive a physical Hamiltonian written in terms of (classical) loop gravity variables. This is done by ga…
