Spin 1/2 from Gluons
A. P. Balachandran
The theta vacuum in QCD is the standard vacuum, twisted by the exponential of the Chern-Simons term. But what is the quantum operator for winding number ? We construct $U…
Discrete Time Evolution and Energy Nonconservation in Noncommutative Physics
A. P. Balachandran, A. G. Martins, P. Teotonio-Sobrinho
Time-space noncommutativity leads to quantisation of time and energy nonconservation when time is conjugate to a compact spatial direction like a circle. In this context energy is…
Waves on Noncommutative Spacetimes
A. P. Balachandran, Kumar S. Gupta, S. Kurkcuoglu
Waves on ``commutative'' spacetimes like R^d are elements of the commutative algebra C^0(R^d) of functions on R^d. When C^0(R^d) is deformed to a noncommutative algebra {\cal A}_θ(…
Edge Currents in Non-commutative Chern-Simons Theory from a New Matrix Model
A. P. Balachandran, K. S. Gupta, S. Kurkcuoglu
This paper discusses the formulation of the non-commutative Chern-Simons (CS) theory where the spatial slice, an infinite strip, is a manifold with boundaries. As standard star pro…
