Out-of-equilibrium spin-valley dynamics of ferromagnets in topological Chern bands
J. James, I. Krastilevskiy, F. Pichler +8
Understanding quantum matter far from equilibrium is a central goal of modern physics. Twisted MoTe2 bilayers constitute a promising platform for exploring this frontier by combini…
Dynamical preparation of U(1) quantum spin liquids in an analogue quantum simulator
Simon Karch, Melissa Will, Irene Prieto Rodriguez +7
Locally constrained gauge theories underpin our understanding of fundamental interactions in particle physics and the emergent behaviour of quantum materials. In strongly correlate…
False Vacuum Decay in Flat-Band Ferromagnets: Role of Quantum Geometry and Chiral Edge States
Fabian Pichler, Clemens Kuhlenkamp, Michael Knap
Dynamical control of quantum matter is a challenging, yet promising direction for probing strongly correlated states. Motivated by recent experiments in twisted MoTe that demon…
Microscopic Mechanism of Anyon Superconductivity Emerging from Fractional Chern Insulators
Fabian Pichler, Clemens Kuhlenkamp, Michael Knap +1
Fractional quantum Hall (FQH) states and superconductors typically require contrasting conditions, yet recent experiments have observed them in the same device. A natural explanati…
Robust superconductivity upon doping chiral spin liquid and Chern insulators in a Hubbard-Hofstadter model
Clemens Kuhlenkamp, Stefan Divic, Michael P. Zaletel +2
Demonstrating superconductivity in purely repulsive Hubbard models is a compelling goal which underscores the counter-intuitive ability of Coulomb interactions to mediate supercond…
First order Quantum Hall to Wigner crystal phase transition on a triangular lattice: an iDMRG study
Gleb Fedorovich, Clemens Kuhlenkamp, Atac Imamoglu +1
In this work we study a system of interacting fermions on a triangular lattice in the presence of an external magnetic field. We neglect spin and fix a density of one third, with o…
