Hartmut Ruhl

Prof. Dr. Hartmut Ruhl is a Professor (chair) at the Faculty of Physics of Ludwig-Maximilians-Universität München (LMU Munich), with his office located at Theresienstrasse 37, Room A237 in Munich, Germany. He leads an active research group focused on high field physics and quantum electrodynamics, particularly investigating radiation reaction, vacuum effects, and strong field phenomena.

Prof. Ruhl's research spans several cutting-edge areas of theoretical and computational physics. His primary interests include high field physics, quantum electrodynamics in strong fields, radiation reaction effects, vacuum polarization phenomena, and computational methods for solving complex physical systems. He has made significant contributions to understanding the Heisenberg-Euler effective Lagrangian, vacuum high harmonic generation, and the Trident process for electron-positron pair production. His work combines theoretical developments with advanced numerical simulations to explore physics in extreme electromagnetic field conditions.

Prof. Ruhl's publication record demonstrates consistent focus on nonlinear quantum electrodynamics in strong fields. His work spans theoretical developments in radiation reaction, numerical methods for solving Heisenberg-Euler equations, and investigations of vacuum effects like high harmonic generation and pair production. A recurring theme is the exploration of quantum vacuum nonlinearities and their observable consequences in high-intensity laser-matter interactions.

Prof. Ruhl actively supervises PhD students in high field physics, requiring profound knowledge in quantum transport theory and advanced programming. His group seeks candidates who have completed his courses in Relativistic Quantum Theory and Advanced Programming. He co-organizes the seminar 'Selected Topics in Computational Physics' with Prof. A. Scrinzi, serving as a platform for master's and PhD students interested in computational plasma physics.

Prof. Ruhl is associated with the Advanced Simulation Center (ASC) at LMU Munich, as indicated by room locations in his teaching schedule. He collaborates closely with Prof. A. Scrinzi on computational physics topics and is involved with the PSC (Plasma Simulation Code) project. His research group develops specialized numerical solvers for nonlinear wave equations based on the Heisenberg-Euler effective Lagrangian, contributing to the understanding of quantum vacuum effects in extreme field conditions.
