Enhanced energy harvesting near exceptional points in systems with (pseudo-)PT-symmetry

Abstract

Optimising energy harvesting is relevant to a variety of micro and nanotechnologies with applications ranging from self powered nanodevices to microfluidic pumps in biological environments. Here, the authors show that an opportunely designed opto(/electro)-mechanical circuit can simultaneously demonstrate high efficiency and power production when operating in the vicinity of an exceptional point degeneracy implemented via a pseudo-PT symmetry.
