Alexander Weiße

Alexander Weiße is a tenured researcher at the Max Planck Institute for Mathematics in Bonn, Germany, where he also serves as Head of IT. Previously, he was a junior professor for computational physics at the University of Greifswald (until 2009). He holds a PhD in physics from the University of Bayreuth (2002) and completed postdoctoral research at the Max Planck Institute for the Physics of Complex Systems, University of New South Wales (Sydney), and University of Greifswald.

Research Interests: His work spans condensed matter physics, mathematical physics, and integrable systems. Recent focuses include spin systems (e.g., XXZ Heisenberg chain), disorder/randomness in quantum systems, and computational methods (e.g., Chebyshev expansion, kernel polynomial method). He also contributes to high-performance computing and programming tools (C, Form, Julia).

Teaching & Leadership: He has taught courses on computational physics, group theory, numerical many-particle physics, and computer algebra. Notable collaborations involve the Bergische Universität Wuppertal group on spin model correlation functions. He co-edited the textbook Computational Many-Particle Physics (Springer, 2008).

IT Responsibilities: As Head of IT, he manages IT infrastructure security and strategy, with interests in cybersecurity and computational resource optimization.
