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:

• 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.

• 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.
