Attraction from repulsion in an interacting Chern band: chiral superconductivity, generalized Hall crystals, and competing fractional Chern insulators
Fabian Pichler, Clemens Kuhlenkamp, Ashvin Vishwanath +1
Experiments realizing strong interactions in partially filled Chern bands have observed fractional Chern insulators (FCIs), superconductors, and topological crystals in close proxi…
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…
Fractionalization from Kinetic Frustration in Doped Two-Dimensional SU(4) Quantum Magnets
Wilhelm Kadow, Ivan Morera, Eugene Demler +1
Separating electrons into emergent fractional quasiparticles is a hallmark of exotic quantum phases of matter with strong interactions. Understanding under which circumstances frac…
Electromagnetic Response of a Half-Filled Chern Band near Topological Criticality
Xinlei Yue, Fabian Pichler, Michael Knap +1
We evaluate electromagnetic-response observables in a half-filled Chern band, across a topological phase transition between a composite Fermi liquid (CFL) and a Fermi liquid (FL) p…
