Enhancement of nonlinear pair production in a flying-focus pulse
Md Reshad Ur Rahman, Martin S. Formanek, Elias Gerstmayr +3
A photon can decay into an electron-positron pair in the presence of an intense laser pulse by a process known as nonlinear Breit-Wheeler pair production (NBWPP). For a sufficientl…
Experimental demonstration of Flying-Focus enhanced Thomson scattering
E. Gerstmayr, C. Mariani, R. Fitzgarrald +23
We report the experimental demonstration of a spatiotemporally engineered "Flying-Focus" laser pulse for enhanced x-ray generation in relativistic Thomson scattering. A combination…
A Reduced Action Integral for Photon-Photon Interactions in Vacuum
D. Ramsey, M. S. Formanek, J. P. Palastro
Electromagnetic waves propagating through vacuum can polarize virtual electron-positron pairs; this polarization, in turn, nonlinearly modifies their propagation. A semi-classical…
Enhanced quantum radiation with flying-focus laser pulses
Martin S. Formanek, John P. Palastro, Dillon Ramsey +1
The emission of a photon by an electron in an intense laser field is one of the most fundamental processes in electrodynamics and underlies the many applications that utilize high-…
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…
Radiation Reaction Enhancement in Flying Focus Pulses
Martin Formanek, Dillon Ramsey, John P. Palastro +1
Radiation reaction (RR) is the oldest still-unsolved problem in electrodynamics. In addition to conceptual difficulties in its theoretical formulation, the requirement of exceeding…
