Nonequilibrium dynamics of doped Chern ferromagnets: a case study for false vacuum decay
Kilian Kuhlbrodt, Olivier Huber, Oliver Breach +7
Even though metastable false vacuum decay is ubiquitous in physics, its underlying dynamics are still not well understood. Dissipative state preparation in moiré quantum materials…

Solvable Quantum Circuits in Tree+1 Dimensions
Oliver Breach, Benedikt Placke, Pieter W. Claeys +1
We devise tractable models of unitary quantum many-body dynamics on tree graphs, as a first step towards a deeper understanding of dynamics in non-Euclidean spaces. To this end, we…

Interferometry of non-Abelian band singularities and Euler class topology
Oliver Breach, Robert-Jan Slager, F. Nur Ünal
In systems with a real Bloch Hamiltonian band nodes can be characterised by a non-Abelian frame-rotation charge. The ability of these band nodes to annihilate pairwise is path depe…
