Intrinsic time gravity and the Lichnerowicz-York equation
Niall Ó Murchadha, Chopin Soo, Hoi-Lai Yu
We investigate the effect on the Hamiltonian structure of general relativity of choosing an intrinsic time to fix the time slicing. 3-covariance with momentum constraint is maintai…
Affine group representation formalism for four dimensional, Lorentzian, quantum gravity
Chou Ching-Yi, Eyo Ita, Chopin Soo
Within the context of the Ashtekar variables, the Hamiltonian constraint of four-dimensional pure General Relativity with cosmological constant, , is reexpressed as an affine al…
New formulation of Horava-Lifshitz quantum gravity as a master constraint theory
Chopin Soo, Jinsong Yang, Hoi-Lai Yu
Both projectable and non-projectable versions of Horava-Lifshitz gravity face serious challenges. In the non-projectable version, the constraint algebra is seemingly inconsistent.…
New length operator for loop quantum gravity
Yongge Ma, Chopin Soo, Jinsong Yang
An alternative expression for the length operator in loop quantum gravity is presented. The operator is background independent, symmetric, positive semidefinite, and well defined o…
Cosmological dynamics with propagating Lorentz connection modes of spin zero
Hsin Chen, Fei-Hung Ho, James M. Nester +2
The Poincare gauge theory of gravity has a Lorentz connection with both torsion and curvature. For this theory two good propagating connection modes, carrying spin- and spin-$…
A Reinvestigation of Moving Punctured Black Holes with a New Code
Zhoujian Cao, Hwei-Jang Yo, Jui-Ping Yu
We report on our code, in which the moving puncture method is applied and an adaptive/fixed mesh refinement is implemented, and on its preliminary performance on black hole simulat…
