Path integration and perturbation theory with complex Euclidean actions
Garnik Alexanian, R. MacKenzie, M. B. Paranjape +1
The Euclidean path integral quite often involves an action that is not completely real {\it i.e.} a complex action. This occurs when the Minkowski action contains -odd CP-violat…
Problems With Complex Actions
G. Alexanian, R. MacKenzie, M. B. Paranjape +1
We consider Euclidean functional integrals involving actions which are not exclusively real. This situation arises, for example, when there are -odd terms in the the Minkowski a…
On plane wave and vortex-like solutions of noncommutative Maxwell-Chern-Simons theory
G. Alexanian, D. Arnaudon, M. B. Paranjape
We investigate the spectrum of the gauge theory with Chern-Simons term on the noncommutative plane, a modification of the description of the Quantum Hall fluid recently proposed by…
Obstruction to D-brane topology change
Garnik G. Alexanian, A. P. Balachandran, Pedro J. Silva
A study of the relation between topology change, energy and Lie algebra representations for fuzzy geometry in connection to -theory is presented. We encounter two different type…
Generalized Coherent State Approach to Star Products and Applications to the Fuzzy Sphere
G. Alexanian, A. Pinzul, A. Stern
We construct a star product associated with an arbitrary two dimensional Poisson structure using generalized coherent states on the complex plane. From our approach one easily reco…
Remarks on Goldstone bosons and hard thermal loops
G. Alexanian, E. F. Moreno, V. P. Nair +1
The hard thermal loop effective action for Goldstone bosons is deduced by symmetry arguments from the corresponding result for gauge bosons. Pseudoscalar mesons in Chromodynamics a…
