Super- and subradiance by entangled free particles
Aviv Karnieli, Nicholas Rivera, Ady Arie +1
When multiple quantum emitters radiate, their emission rate may be enhanced or suppressed due to collective interference in a process known as super- or subradiance. Such processes…
Control of quantum electrodynamical processes by shaping electron wavepackets
Liang Jie Wong, Nicholas Rivera, Chitraang Murdia +4
Fundamental quantum electrodynamical (QED) processes such as spontaneous emission and electron-photon scattering encompass a wealth of phenomena that form one of the cornerstones o…
Towards atomic-resolution quantum measurements with coherently-shaped free electrons
Ron Ruimy, Alexey Gorlach, Chen Mechel +2
Free electrons provide a powerful tool to probe material properties at atomic-scale spatial resolution. Recent advances in ultrafast electron microscopy enable the manipulation of…
Variational theory of non-relativistic quantum electrodynamics
Nicholas Rivera, Johannes Flick, Prineha Narang
The ability to achieve ultra-strong coupling between light and matter promises to bring about new means to control material properties, new concepts for manipulating light at the a…
Controlling light emission with electron wave interference
Chitraang Murdia, Nicholas Rivera, Thomas Christensen +4
It is a long standing question whether or not one can change the nature of spontaneous emission by a free electron through shaping the electron wavefunction. On one hand, shaping t…
Shaping Long-lived Electron Wavepackets for Customizable Optical Spectra
Rumen Dangovski, Nicholas Rivera, Marin Soljacic +1
Electrons in atoms and molecules are versatile physical systems covering a vast range of light-matter interactions, enabling the physics of Rydberg states, photon-photon bound stat…
