Further simplification of the constraints of four-dimensional gravity
Chopin Soo
The super-Hamiltonian of 4-dimensional gravity as simplified by Ashtekar through the use of gauge potential and densitized triad variables can furthermore be succinctly expressed a…

Effective gauge group of pure loop quantum gravity is SO(3): New estimate of the Immirzi parameter
Chung-Hsien Chou, Yi Ling, Chopin Soo +1
We argue that the effective gauge group for {\it pure} four-dimensional loop quantum gravity(LQG) is SO(3) (or ) instead of SU(2) (or ). As a result, links with h…

Free spin quantum computation with semiconductor nanostructures
Wei-Min Zhang, Yin-Zhong Wu, Chopin Soo
Taking the excess electron spin in a unit cell of semiconductor multiple quantum-dot structure as a qubit, we can implement scalable quantum computation without resorting to spin-s…
