Tim Bode

I lead Quicopt — a quantum-inspired optimization spin-off out of Forschungszentrum Jülich.

Previously: PhD in condensed-matter and many-body theory at the University of Bonn (summa cum laude, 2021). MSc and BSc from ETH Zurich.

Research

My work runs from non-equilibrium field theory through mean-field optimization to beyond-mean-field corrections, with sidelines into field-theoretic methods for stochastic processes (J. Phys. A) and experimental photon condensation (Science) — first-, last-, and sole-author contributions among them.
