| Research Abstract |
High energy particles or cosmic rays are ubiquitous in the universe, yet their origins have been a long standing unsolved problem for more than a century. Recent observations of very fast acceleration of cosmic rays imply that the magnetic field has to be amplified by orders of magnitude. However, it is impossible to observe the local magnetic field in distant astrophysical phenomena. We model such phenomena in laboratories and perform proof-of-principal experiments with lasers.
