Quasi-Static Direct Laser Acceleration -- Particle in Cell Simulation.
QS-DLA-PIC is a serial quasi-static particle-in-cell simulation code, written in the forgotten language Fortran. Developed by Tianhong Wang in 2017, at Dr. Gennady Shvets' Group, Cornell University.

QS-DLA-PIC is a FORTRAN-based serial simulation tool developed during my research. I first developed this code with Dr. Vladimir N. Khudik to verify some new equations we derived and also to simulate plasma wave driven by the point-charge. Then this code is upgraded to simulate laser-driven and beam driven plasma wakefield acceleration. Although QS-DLA is a 'single-core' simulation code, it's still very fast on most desktops due to the new equations we used. And you don't need to wait in the queue! It serves as a great tool if you just want to do some small-size simulations, or do a quick check of simulation parameters before you run larger 3D simulation on the supercomputers. More-powerful WAND-PIC has been developed by me later, but this is still a irreplaceable tool in my research.
