Cosmic time and the initial state of the universe
Chopin Soo
The exact solution of the Hamiltonian constraint in canonical gravity and the resultant reduction of Einstein's theory reveal the synergy between gravitation and the intrinsic cosm…
Quantization of constrained systems as Dirac first class versus second class: a toy model and its implications
Eyo Eyo Ita, Chopin Soo, Abraham Tan
A toy model (suggested by Klauder) is analyzed from the perspective of First Class and Second Class Dirac constrained systems. The comparison is made by turning a First Class into…
Cosmic time and reduced phase space of General Relativity
Eyo Eyo Ita, Chopin Soo, Hoi-Lai Yu
In an ever-expanding spatially closed universe, the fractional change of the volume is the preeminent intrinsic time interval to describe evolution in General Relativity. The expan…
Intrinsic time gravity, heat kernel regularization, and emergence of Einstein's theory
Eyo Eyo Ita, Chopin Soo, Hoi-Lai Yu
The Hamiltonian of Intrinsic Time Gravity is elucidated. The theory describes Schrodinger evolution of our universe with respect to the fractional change of the total spatial volum…
Gravitational waves in Intrinsic Time Geometrodynamics
Eyo Eyo Ita, Chopin Soo, Hoi-Lai Yu
Gravitational waves are investigated in Intrinsic Time Geometrodynamics. This theory has a non-vanishing physical Hamiltonian generating intrinsic time development in our expanding…
Quantum geometrodynamics with intrinsic time development
Chopin Soo
Quantum geometrodynamics with intrinsic time development is presented. Paradigm shift from full space-time covariance to spatial diffeomorphism invariance yields a non-vanishing Ha…
