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…
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…
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…
Phase Control of Nonlinear Breit-Wheeler Pair Creation
B. Barbosa, J. P. Palastro, D. Ramsey +2
Electron-positron pair creation occurs throughout the universe in the environments of extreme astrophysical objects, such as pulsar magnetospheres and black hole accretion disks. T…
