Localization of nonlocal theories
Gianluca Calcagni, Michele Montobbio, Giuseppe Nardelli
We show that a certain class of nonlocal scalar models, with a kinetic operator inspired by string field theory, is equivalent to a system which is local in the coordinates but non…
Route to nonlocal cosmology
Gianluca Calcagni, Michele Montobbio, Giuseppe Nardelli
An analytic approach to phenomenological models inspired by cubic string field theory is introduced and applied to some examples. We study a class of actions for a minimally couple…
Noncommutative Two Dimensional BF Model
Alberto Blasi, Nicola Maggiore, Michele Montobbio
We consider the noncommutative extension of the BF theory in two spacetime dimensions. We show that the introduction of the noncommutative parameter θ_{μν}, already at first order…
Instabilities of noncommutative two dimensional BF model
Alberto Blasi, Nicola Maggiore, Michele Montobbio
The noncommutative extension of two dimensional BF model is considered. It is shown that the realization of the noncommutative map via the Groenewold-Moyal star product leads to in…
