Quantum optics of spatial transformation media
Ulf Leonhardt, Thomas G. Philbin
TL;DR
This paper develops a quantum theoretical framework for transformation media, which are crucial in advanced optical devices like invisibility cloaks and perfect lenses, by mapping quantum electromagnetism in such media to standard QED.
Contribution
It introduces a quantum theory for transformation media, linking their electromagnetic properties to quantum electrodynamics in flat space, advancing understanding of their quantum behavior.
Findings
Transformation media map quantum electromagnetism to flat space QED
Provides a quantum framework for invisibility devices and lenses
Enhances understanding of quantum effects in transformation optics
Abstract
Transformation media are at the heart of invisibility devices, perfect lenses and artificial black holes. In this paper, we consider their quantum theory. We show how transformation media map quantum electromagnetism in physical space to QED in empty flat space.
