The Universe as a driven quantum system: Unbounded heating in cyclic cosmologies
J. P. P. Vieira
The Hamiltonian of an evolving Universe is shown to be formally equivalent to that of a driven quantum system, whose driving follows from the temporal dependence of the spacetime m…

Quadratic Models for Engineered Control of Open Quantum Systems
J. P. P. Vieira, A. Lazarides, T. Ala-Nissila
We introduce a framework to model the evolution of a class of open quantum systems whose environments periodically undergo an instantaneous non-unitary evolution stage. For the spe…
