Strong-field nano-optics

Reviews of Modern Physics, Journal Year: 2020, Volume and Issue: 92(2)

Published: June 9, 2020

When electromagnetic fields impinge on nanoscale structured materials, optical field concentrations can occur that enhance the strength up to 2 orders of magnitude. The strong-field interaction physics enabled by these nano-optical building blocks probes highly nonlinear phenomena pave way toward unique matter such as ultrafast electron imaging and spectroscopy ultrahigh frequency transistor concepts are preludes light-wave electronics. This article reviews fundamentals applications phenomena.

Attosecond coherent control of free-electron wave functions using semi-infinite light fields

Nature Communications, Journal Year: 2018, Volume and Issue: 9(1)

Published: July 6, 2018

Light-electron interaction in empty space is the seminal ingredient for free-electron lasers and also controlling electron beams to dynamically investigate materials molecules. Pushing coherent control of free electrons by light unexplored timescales, below attosecond, would enable unprecedented applications light-assisted quantum circuits diagnostics at extremely small such as those governing intramolecular electronic motion nuclear phenomena. We experimentally demonstrate attosecond manipulation wave function a transmission microscope, show that it can be pushed down zeptosecond regime with existing technology. make relativistic pulsed beam interact an appropriately synthesized semi-infinite field generated two femtosecond laser pulses reflected surface mirror delayed fractions optical cycle. The amplitude phase resulting oscillations states energymomentum are mapped via momentum-resolved ultrafast energy-loss spectroscopy. experimental results full agreement our theoretical framework light-electron interaction, which predicts access timescale combining X-ray fields electrons.

Entanglements of Electrons and Cavity Photons in the Strong-Coupling Regime

Physical Review Letters, Journal Year: 2019, Volume and Issue: 123(10)

Published: Sept. 6, 2019

This Letter sets a road map towards an experimental realization of strong coupling between free electrons and photons analytically explores entanglement phenomena that emerge in this regime. The proposed model unifies the strong-coupling predictions with known electron-photon interactions. Additionally, predicts non-Columbic freely propagating electrons. Since can entanglements photon pairs onto photon-electron pairs, it may harness electron beams for quantum communication, thus far exclusive to photons.
