Casimir effect in 2+1 dimensional noncommutative theories
C. D. Fosco, G. A. Moreno
We study the Dirichlet Casimir effect for a complex scalar field on two noncommutative spatial coordinates plus a commutative time. To that end, we introduce Dirichlet-like boundar…
One-loop effects in a self-dual planar noncommutative theory
C. D. Fosco, G. A. Moreno
We study the UV properties, and derive the explicit form of the one-loop effective action, for a noncommutative complex scalar field theory in 2+1 dimensions with a Grosse-Wulkenha…
Noncommutative real scalar field theory in 2+1 dimensions at finite temperature
C. D. Fosco, G. A. Silva
We study thermal effects for a noncommutative real scalar field in 2+1 dimensions including a Grosse-Wulkenhaar term. Using a perturbative expansion for the free energy, we deduce…
Quantum dissipative effects in moving mirrors: a functional approach
C. D. Fosco, F. C. Lombardo, F. D. Mazzitelli
We use a functional approach to study various aspects of the quantum effective dynamics of moving, planar, dispersive mirrors, coupled to scalar or Dirac fields, in different numbe…
A simple derivation of the Overlap Dirac Operator
C. D. Fosco, G. Torroba, H. Neuberger
We derive the vector-like four dimensional overlap Dirac operator starting from a five dimensional Dirac action in the presence of a delta-function space-time defect. The effective…
A new path integral representation for the thermal partition function
C. D. Fosco, A. P. C. Malbouisson, I. Roditi
The boundary conditions corresponding to the Matsubara formalism for the partition function may be introduced as {\em constraints} in the path integral for the vacuum ampli…
