    Macroscopic Quantum Electrodynamics and its Consequences<\/strong><\/strong>.<\/h3>\n\n\n\n

    The Heisenberg uncertainty principle implies that the electric field exhibits fluctuations even in its vacuum state. These fluctuations, also known as virtual photons, couple to any charged or polarisable system, leading to a number of surprising effects: the Lamb shift, spontaneous decay and the Purcell effect, resonant energy transfer, dispersion interactions of Casimir, Casimir-Polder and van der Waals type and contact-less quantum friction. This project investigates how these unavoidable consequences of quantum electrodynamics can be manipulated: Can unusual media such as Chern-Simons materials or topological insulators be used to detect CP violation or discriminate chiral enantiomers? Can the fundamental van der Waals potential between two atoms acquire a spatially oscillating profile for excited atoms? How can this potential be changed by means of background media? Can carefully tuned resonances help enhance quantum friction to facilitate its first experimental observation? How will environments modify or facilitate resonant energy transfer and interatomic Coulomb decay?<\/p>\n\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\t<\/div>\n<\/article>\n<\/div>\n<\/div>\n\n\n\n
