On the stability of Born-Infeld-regularised electroweak monopoles
N E Mavromatos, Sarben Sarkar
The Cho-Maison monopole provides a monopole solution of the electroweak field equations, but possesses an infinite classical energy due to the Maxwell form of the hypercharge secto…

The axion coupling accelerates the Universe through PT-symmetric phases
Leqian Chen, Nick E. Mavromatos, Sarben Sarkar
The conjecture by two of the authors (N.E.M. and S.S.) that a \cPT-symmetric phase plays a role in understanding singular renormalisation group (RG) flows for a Chern-Simons (CS) g…

Quantum Excitation Transfer in an Artificial Photosynthetic Light-Harvesting System
Stephon Alexander, Roger Andrews, Oliver Fox +1
We analytically derive transfer probabilities and efficiencies for an artificial light-harvesting photosynthetic system, which consists of a ring coupled to a central acceptor. For…
