Topological defects in nonlocal field theories
Luca Buoninfante, Yuichi Miyashita, Masahide Yamaguchi
In this paper, we study for the first time topological defects in the context of nonlocal field theories in which Lagrangians contain infinite-order differential operators. In part…
Gravitational field of scalar lumps in higher-derivative gravity
Luca Buoninfante, Yuichi Miyashita
We study the gravitational field sourced by localized scalar fields (lumps) in higher-derivative theories of gravity. By working in a static and spherically symmetric configuration…
Generalized ghost-free propagators in nonlocal field theories
Luca Buoninfante, Gaetano Lambiase, Yuichi Miyashita +2
In this paper we present an iterative method to generate an infinite class of new nonlocal field theories whose propagators are ghost-free. We first examine the scalar field case a…
