Enhanced Schwinger's pair production in many-center systems
François Fillion-Gourdeau, Emmanuel Lorin, André D. Bandrauk
Electron-positron pair production is considered for many-center systems with multiple bare nuclei immersed in a constant electric field. It is shown that there are two distinct reg…
A Split-Step Numerical Method for the Time-Dependent Dirac Equation in 3-D Axisymmetric Geometry
François Fillion-Gourdeau, Emmanuel Lorin, André D. Bandrauk
A numerical method is developed to solve the time-dependent Dirac equation in cylindrical coordinates for 3-D axisymmetric systems. The time evolution is treated by a splitting sch…
Atoms and Molecules in Intense Laser Fields: Gauge Invariance of Theory and Models
André D. Bandrauk, François Fillion-Gourdeau, Emmanuel Lorin
Gauge invariance was discovered in the development of classical electromagnetism and was required when the latter was formulated in terms of the scalar and vector potentials. It is…
On the Saturation of the Nonlinear Refractive Index in Atomic Gases
Christian Köhler, Roland Guichard, Emmanuel Lorin +4
Motivated by the ongoing controversy on the origin of the nonlinear index saturation and subsequent intensity clamping in femtosecond filaments, we study the atomic nonlinear polar…
