Welcome to my homepage!
I'm a researcher in the ConQuEr group at the Friedrich-Alexander-Universität Erlangen-Nürnberg in Erlangen, Germany. My research interests cover a lot of stuff concerning the mathematical and theoretical aspects of quantum mechanics and quantum field theories. You can always reach me by e-mail for discussions or potential collaborations.

New preprint out! We prove that quantum mechanical (bi)probabilities satisfy a generalized Kolmogorov extension theorem: while one cannot interpret such distributions as the result of the sampling of a single trajectory, they do result from the sampling of one pair of trajectories. In this sense, rather than give up on trajectories, quantum mechanics requires to double down on them!
New preprint out! We find sufficient conditions to achieve global approximate controllability of quantum systems defined by a form perturbation of some drift Hamiltonian, and we apply them to a particle in a box with a Dirac delta potential.
New paper out! We show that, for any quantum system whose Hamiltonian has a finite ground state energy, the average value of any quantum observable cannot converge exponentially to an extremal value of its spectrum. This generalizes Khalfin's classic argument on the large-time behavior of survival probabilities.
