New type of closed timelike curves from quantum gravity

We will present a novel construction of the closed timelike curves (CTC) type of solutions, in the context of an abstract formalism of quantum gravity. The new CTC solutions are constructed via the quantum superposition of two regular configurations of the gravitational field in a globally hyperbolic spacetime topology, which is an unusual feature of CTC solutions. A quantum-mechanical particle traveling through such a superposed gravitational field behaves as traveling through a CTC, while also interacting with two agents (Alice and Bob) at two distinct spacetime points. Work done in collaboration with N. Paunković.
