Valentin W. Weitemeyer

I am a M.Sc. Physics student at Heidelberg University, specialising in Mathematical Physics and Renormalisation Group Methods. My Bachelor’s thesis — Random Walk Representations of Discrete Quantum Field Theories — studied Euclidean quantum field theories through the lens of quantum statistical mechanics.

\[[m^2-\Delta]^{-1}_{ij} = \sum_{\omega:i\to j}\left(\frac{1}{2d + m^2}\right)^{\ell(\omega)}\]

Alongside my studies I work as a HiWi on the typesetting of a physics lecture script, and previously served as a tutor. In Winter 2024/25 I spent a semester abroad at the University of Southern Denmark (SDU) through the Erasmus programme, where I took courses in Quantum Field Theory, Advanced Statistical Physics, and Operator Algebras.

\[(\Lambda - J)^{-1}_{ij} = \sum_{\omega:i\to j}J_{\omega} \prod_{k \in L} \frac{1}{\lambda_k^{n(k,\omega)}}\]
