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…
Spontaneous breaking of conformal invariance, solitons and gravitational waves in theories of conformally invariant gravitation
Jihene Bouchami, M. B. Paranjape
We study conformal gravity as an alternative theory of gravitation. For conformal gravity to be phenomenologically viable requires that the conformal symmetry is not manifest at th…
Quasi-hole solutions in finite noncommutative Maxwell-Chern-Simons theory
Jules Lambert, M. B. Paranjape
We study Maxwell-Chern-Simons theory in 2 noncommutative spatial dimensions and 1 temporal dimension. We consider a finite matrix model obtained by adding a linear boundary field w…
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…
Spontaneous breaking of conformal invariance in theories of conformally coupled matter and Weyl gravity
A. Edery, Luca Fabbri, M. B. Paranjape
We study the theory of Weyl conformal gravity with matter degrees of freedom in a conformally invariant interaction. Specifically, we consider a triplet of scalar fields and SO(3)…
The abelian and non-abelian Josephson effect and pseudo-goldstone bosons
Paul Esposito, L. -P. Guay, R. B. MacKenzie +2
We formulate the Josephson effect in a field theoretic language which affords a straightforward generalization to the non-abelian case. We give some examples and apply the formalis…
