Noncommutative Solitons and the W_{1+\infty} Algebras in Quantum Hall Theory
Chuan-Tsung Chan, Jen-Chi Lee
We show that U(\infty) symmetry transformations of the noncommutative field theory in the Moyal space are generated by a combination of two W_{1+\infty} algebras in the Landau prob…
Equivalent Relations between Quantum Dynamics as Derived from a Gauge Transformation
Chuan-Tsung Chan, Chun-Khiang Chua
Equivalent relations between quantum mechanical systems in the Robertson-Walker (RW) background metric and quantum dynamics with an induced quadratic background potential are deriv…
Nucleon Electric Dipole Moments from QCD Sum Rules
Chuan-Tsung Chan, Ernest M. Henley, Thomas Meissner
The electric dipole moments of nucleons (NEDM, d_N) are calculated using the method of QCD sum rules. Our calculations are based on the parity and time reversal violating parameter…
On the Symmetry Constraints of CP Violations in QCD
Chuan-Tsung Chan
Three symmetry constraints on the CP violations in QCD are discussed in this paper. In order to generate CP violating observables from QCD, these constraints require: (1) spontaneo…
