Thore Posske CV, Google Scholar

Thore likes physics 'with a twist'. He is particulary interested in topologically robust phenomena in spin chains, anyons, and Majorana fermions with a possible application to quantum computing. He also works on the Kondo effect for topological electronic phases with special focus on the Kondo cloud as well magnetic and superconducting materials at the edge states of topological insulators and hybrid systems consisting of a trivial insulator and a topological insulator.

Martin Bonkhoff (PhD)

Martin's heart beats bosonization. As expert for anyons in ERC Starting Grant project QUANTWIST, Martin bosonizes and applies other field theoretical tools to low-dimensional theories and extracts the quasi-particles' characteristic properties.

Olesia Krupnitzka (PhD) Google Scholar

Olesia thinks about experimental realizations of magnetic models with nontrivial properties like the Kitaev-Heisenberg model.

Felix Gerken (MSc) Google Scholar

Felix is passionate about the topological spin phases. He considers a vast range of analytical tool, including Hopf algebras, the Bethe ansatz, and fusion categories for fining exact solutions to low-dimensional spin models with boundaries.

Ioannis Ioannidis (MSc) Google Scholar

Giannis quest is to understand the Majorana modes in the novel platform of magnetic adatoms on superconductors. He is interested in magnetic manipulation, spin resonances, and time-dependent methods.

Anshuman Tripathi (MSc)

Anshuman wants to study topological effects in spin structures. An intriguing question is if nonlinear sigma models will help achieve the analytical insight he strives for

Tim Matthies

Tim is longing for key insights in density functional theory and previously was most interested in machine learning applications in topological condensed matter physics. He is PhD student at Elena Vedmedenko's group and a frequent visitor.

Marc Sauter

Marc is a joint MSc. student of the Ingo Runkel (UHH maths department) and our group. He is strong in conformal field theory and reverse engineering quantum spin chain Hamiltonians.

Zhi Zhen Ong

In his MIT summer internship 2026, Zhi Zheng explores real-time time control of quantum states in noise intermediate scale quantum computers, and aims for hardware level improvements of Trotter splitting to find stable noncollinear quantum magnetism.
