High-order exponential solver method for particle-in-cell simulations in cylindrical geometry
Szilárd Majorosi, Nasr A. M. Hafz, Zsolt Lécz
Recent developments in high peak-power table-top laser systems reaching highly relativistic light intensities have led to significant advances in laser-driven particle acceleration…
Asymmetry in laser wakefields driven by intense pulses
Zsolt Lécz, Szilárd Majorosi
Laser wakefield theories rely on the laser envelope function, which is radially symmetric, and predict zero transverse momentum for the electrons along the propagation axis. Exact…
High-order exponential solver method for particle-in-cell simulations
Szilárd Majorosi, Nasr Hafz, Zsolt Lécz
Outstanding advances in solid-state laser technology, employing the optical parametric chirped-pulse-amplification (OPCPA) technique, have led physicists to focus laser pulses to h…
Single-mode laser guiding in non-parabolic plasma channels for high-energy electron acceleration
Zsolt Lécz, Szilárd Majorosi, Nasr A. M. Hafz
The discovery of laser wakefield acceleration in gaseous plasma was a major milestone that could lead to a significant reduction of size and cost of large electron accelerators. Fo…
