Quantum Origin of (Newtonian) Mass and Symmetry for Lorentz Covariant Physics
Otto C. W. Kong, Hock King Ting
The Galilean symmetry and the Poincare symmetry are usually taken as the fundamental (relativity) symmetries for `nonrelativistic' and `relativistic' physics, respectively, quantum…

Mixed State Parametrization and Two-qubit Entanglement
Otto C. W. Kong, Hock King Ting
A generic scheme for the parametrization of mixed state systems is introduced, which is then adapted to bipartite systems, especially to a 2-qubit system. Various features of 2-qub…
