Welcome to my homepage!

I am a researcher and Habilitant in the ConQuEr group at the Friedrich-Alexander-Universität Erlangen-Nürnberg in Erlangen, Germany. My research activities 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.

News:

• New paper on arXiv: we establish that a wide family of operators describing k-photon light–matter interactions (k≥3), including the k-photon Rabi model, admit a 2k-dimensional space of distinct self-adjoint realizations.

• New paper on arXiv: we provide a general construction of effective Hamiltonians approximating the dynamics of unbounded time-periodic Hamiltonians up to the desired order, and show that it reproduces the Floquet–Magnus (FM) expansion whenever the latter is defined, thus providing the first extension of FM to the unbounded case. 

• New paper on arXiv: we analyze how the full family of self-adjoint extensions of some Jacobi operators can be reproduced via small diagonal perturbations, and apply this knowledge to higher-order squeezing operators in quantum optics.
