X-ray free-electron lasing in a flying-focus undulator
D. Ramsey, B. Malaca, T. T. Simpson +5
Laser-driven free-electron lasers (LDFELs) replace magnetostatic undulators with the electromagnetic fields of a laser pulse. Because the undulator period is half the wavelength of…
Radiation by a laser-driven flying-focus electron wave packet
Antonino Di Piazza, Martin Formanek, Dillon Ramsey +1
An exact solution of the Dirac equation in the presence of an arbitrary electromagnetic plane wave is found, which corresponds to a focused electron wave packet, with the focus of…
Superluminal matter waves
J. P. Palastro, D. Ramsey, M. Formanek +2
The Dirac equation has resided among the greatest successes of modern physics since its emergence as the first quantum mechanical theory fully compatible with special relativity. T…
