Alexander Stottmeister

Dr. Alexander Stottmeister is a researcher and group leader at the Institute of Theoretical Physics within the Faculty of Mathematics and Physics at Leibniz University Hannover. His primary research focuses on theoretical and mathematical aspects of quantum theory at the intersection of quantum information theory and quantum field theory. His group explores foundational concepts such as operator-algebraic renormalization, quantum simulation algorithms with error bounds, and applications of classical probability methods to the renormalization group. They also investigate mathematical frameworks for quantum theory, including Schmidt rank, embezzlement, and semi-group theory.

Key research areas include:

• Renormalization group approaches using operator algebras and functional analysis
• Quantum simulation of conformal field theories
• Entanglement embezzlement in relativistic quantum fields
• Mathematical structures in quantum information and quantum field theory

Notable achievements include the development of operator-algebraic renormalization techniques and contributions to understanding entanglement properties of quantum fields. His work is supported by the Stay Inspired program of Lower Saxony's Ministry of Science.

Students advised include doctoral candidate Lauritz van Luijk and master's student Tobias Pahlke. Recent publications highlight advancements in entanglement embezzlement, lattice Green functions, and mathematical foundations of quantum systems.
