Welcome to my homepage!

I am a researcher and Habilitand 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:

• My lecture notes on mathematical foundations of second quantization are now available on arXiv, in a revised and enlarged form.

• New paper on arXiv: we present an algorithm that decides, from the coefficients of a Hermitian polynomial in x and p alone, whether it defines exactly one quantum dynamics, none, or infinitely many — and a web interface that runs it in the browser.

• New paper on arXiv: we quantitatively assess the validity of the rotating-wave approximation for spin–boson models with a structured boson field.

• 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 distinct self-adjoint realizations indexed by 2k×2k unitary matrices.
