Andrzej Fleszar

Dr. Andrzej Fleszar is affiliated with the Department of Theoretical Physics I at the University of Würzburg. His research focuses on condensed matter physics, particularly in computational quantum materials, electronic structure calculations, and spin-orbit coupling effects. He has contributed to studies on topological insulators, surface physics, and strongly correlated electron systems. His work often utilizes density functional theory (DFT) and explores phenomena such as charge ordering, band inversion, and quantum phase transitions. Fleszar's publications span topics like two-dimensional metallicity, frustrated lattices, and topological surface states. He has been part of the Theoretical Physics I team and is associated with the Wilhelm Wien Institute.

Research interests include:

• Topological insulators and their electronic properties
• Spin-orbit coupling in surface and low-dimensional systems
• Computational modeling of semiconductor surfaces and defects
• Quantum phase transitions in frustrated lattices

His articles highlight advancements in understanding materials like Sn/SiC, Au/Ge surfaces, and strained Sn-based systems. Fleszar's work bridges theoretical predictions with experimental techniques like X-ray spectroscopy and angle-resolved photoemission.
