Multiband Superconductivity in the Exactly Solvable Hatsugai-Kohmoto Model
Nico Hahn, R. Matthias Geilhufe
Multiband superconductivity gives rise to a rich landscape of possible pairing states. Here we study superconductivity in the multiband extension of the Hatsugai-Kohmoto model, an…
Collective Buckling in Metal-Organic Framework Materials
Nico Hahn, Lars Ãhrström, R. Matthias Geilhufe
We develop a framework to describe collective buckling in metal-organic frameworks (MOFs). Starting from the microscopic structure of a single organic linker, we define a buckling…
Quantifying non-Markovianity in magnetization dynamics via entropy production rates
Felix Hartmann, Finja Tietjen, R. Matthias Geilhufe +1
Magnetization dynamics is commonly described by the stochastic Landau-Lifshitz-Gilbert (LLG) equation. On picosecond timescales, inertial and open-system extensions of the LLG equa…
Inertial Repulsion from Quantum Geometry
Maike Fahrensohn, R. Matthias Geilhufe
We derive a repulsive, charge-dipole-like interaction for a Dirac particle in a rotating frame, arising from a geometric gauge symmetry associated with the Berry phase. The…
Axial phono-magnetic effects
Natalia Shabala, Finja Tietjen, R. Matthias Geilhufe
Axial or circularly polarized phonons are collective lattice vibrations with angular momentum. Over the past decade they have emerged as a promising mechanism for the manipulation…
Prediction of Molecular Single-Photon Emitters: A Materials-Modelling Approach
Erik Karlsson Ãhman, Daqing Wang, R. Matthias Geilhufe +1
Interfacing light with quantum systems is an integral part of quantum technology, with the most essential building block being single-photon emitters. Although various platforms ex…
