Spectrum of Schroedinger field in a noncommutative magnetic monopole
D. Karabali, V. P. Nair, A. P. Polychronakos
The energy spectrum of a nonrelativistic particle on a noncommutative sphere in the presence of a magnetic monopole field is calculated. The system is treated in the field theory l…
Calogero-Moser models with noncommutative spin interactions
Alexios P. Polychronakos
We construct integrable generalizations of the elliptic Calogero-Sutherland-Moser model of particles with spin, involving noncommutative spin interactions. The spin coupling potent…
Area Potentials and Deformation Quantization
Thomas L Curtright, Alexios P Polychronakos, Cosmas K Zachos
Systems built out of N-body interactions, beyond 2-body interactions, are formulated on the plane, and investigated classically and quantum mechanically (in phase space). Their Wig…
Quest for Localized 4-D Black Holes in Brane Worlds
Panagiota Kanti, Kyriakos Tamvakis
We investigate the possibility of obtaining localized black hole solutions in brane worlds by introducing a dependence of the four-dimensional line--element on the extra dimension.…
On the nuclear dependence of the mu-e conversion branching ratio
T. S. Kosmas
The variation of the coherent branching ratio (ratio of the reaction rate divided by the total muon-capture rate) through the periodic table is studied by usi…
On the stability of nontopological solitons in supersymmetric extensions of the Standard Model: A Numerical Approach
G. K. Leontaris, A. Prikas, A. Spanou +2
In various supersymmetric extensions of the Standard Model there appear non-topological solitons due to the existence of U(1) global symmetries associated with Baryon and/or Lepton…
