Aharonov-Bohm Effect in Noncommutative Spaces
M. Chaichian, A. Demichev, P. Presnajder +2
The Aharonov-Bohm effect on the noncommutative plane is considered. Developing the path integral formulation of quantum mechanics, we find the propagation amplitude for a particle…
Space-Time Noncommutativity, Discreteness of Time and Unitarity
M. Chaichian, A. Demichev, P. Presnajder +1
Violation of unitarity for noncommutative field theory on compact space-times is considered. Although such theories are free of ultraviolet divergences, they still violate unitarit…
Field Theory on Noncommutative Space-Time and the Deformed Virasoro Algebra
M. Chaichian, A. Demichev, P. Presnajder
We consider a field theoretical model on the noncommutative cylinder which leads to a discrete-time evolution. Its Euclidean version is shown to be equivalent to a model on the com…
