Integrable sub-Riemannian geodesic flows on the special orthogonal group
Alejandro Bravo-Doddoli, Philip Arathoon, Anthony M. Bloch
We analyse the geometry of the rubber-rolling distribution on the special orthogonal group and show that almost all the normal geodesics of any right-invariant sub-Riemannian metri…

Fluctuations in Hill's equation parameters and application to cosmic reheating
Leia Barrowes, Fred C. Adams, Anthony M. Bloch +1
Cosmic inflation provides a compelling framework for explaining several observed features of our Universe, but its viability depends on an efficient reheating phase that converts t…

Generalized Models for Inflationary Preheating: Oscillations and Symmetries
Leia Barrowes, Fred C. Adams, Anthony M. Bloch +2
The paradigm of the inflationary universe provides a possible explanation for several observed cosmological properties. In order for such solutions to be successful, the universe m…
