Research

I am a condensed matter physicist with a background in non-equilibrium quantum many-body systems. In my PhD project, I am currently working in the field of topology and quantum geometry. For more feel free to browse my publications.

A Conjecture Regarding Ground State Overlaps
Prof. Dr. Stefan Kehrein
University of Göttingen, Germany
In this thesis, the validity of a potential extension of the adiabatic theorem to quantum quenches, i.e., non-adiabatic changes, is examined. In particular, the Transverse Field Ising Model (TFIM) and the Axial Next Nearest Neighbour Ising (ANNNI) Model model are studied. The proposed extension of the adiabatic theorem is framed as follows: as long as quenched states within the same magnetic phase are concerned, the overlap between the initial and final ground states is the largest possible, i.e., maximal. In the case of the TFIM, this conjecture is confirmed for both the paramagnetic and ferromagnetic phases numerically and analytically. In the ANNNI model, the conjecture could be analytically proven for a special case. To investigate the conjecture's validity beyond this special case, numerical methods were employed. Violations of the conjecture in the numerical analysis of the ANNNI model were observed and examined regarding their potential relation to finite-size effects.
