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…
Detecting Exciton Condensation through Charge Transport in Semiconductor Heterostructures
Caterina Zerba, Léo Mangeolle, Michael Knap
Direct evidence of exciton condensation in semiconductor heterostructures remains elusive. Here we propose charge transport of doped carriers as a probe of exciton condensation in…
Tensor network study of deconfined quantum criticality in a one-dimensional spin-phonon model
Anton Romen, Josef Willsher, David Hofmeier +2
Deconfined quantum critical points (DQCPs) describe continuous transitions between ordered phases beyond the Landau paradigm. A simple example is the Néel antiferromagnet (AFM) to…
Generalized Hydrodynamics of Bloch Oscillations in the Absence of a Lattice
Stefano Scopa, Philip Zechmann, Michael Knap +2
Objects subjected to a constant force generally increase their velocity over time. This expectation fails whenever their energy is a smooth and periodic function of momentum, resul…
Theory of Angle Resolved Photoemission Spectroscopy of Altermagnetic Mott Insulators
Lorenzo Lanzini, Purnendu Das, Michael Knap
Altermagnetism has emerged as an unconventional form of collinear magnetism with spatial rotational symmetries, that give rise to strongly spin-split bands despite of an underlying…
Purely electronic model for exciton-polaron formation in moiré heterostructures
Fabian Pichler, Mohammad Hafezi, Michael Knap
Understanding interactions between excitons and correlated electronic states presents a fundamental challenge in quantum many-body physics. Here, we introduce a purely electronic m…
