Proximity-induced charge density waves in a moiré heterobilayer
Christopher T. S. Cheung, Arash A. Mostofi, Johannes Lischner
Twisted heterobilayers of two-dimensional materials have emerged as a platform for studying emergent phases of matter. In this work, we investigate charge density waves (CDW) in a…
Exciton multipolarity controls coherent and squeezed phonons in van der Waals heterostructures
Indrajit Maity, Arash A. Mostofi, Johannes Lischner +1
Photoexcitation-driven changes in the electronic distribution displace atoms, generating coherent phonons on ultrafast timescales. Two-dimensional (2D) materials and their heterost…
Moiré trapping of quadrupolar excitons in van der Waals trilayers
Indrajit Maity, Arash A. Mostofi, Ángel Rubio +1
Quadrupolar excitons in van der Waals heterostructures - quantum superpositions of anti-aligned dipolar excitons - offer a novel platform to explore exotic many-body physics, with…
Phase engineering of 1T and 1T CrS2 and Cr2S3 by MOCVD
Haoyu Bai, Gareth R. M Tainton, Mauro Och +21
Layered Cr-chalcogenides compounds offer a rich range of crystal phases with different magnetic properties some of which have been predicted only but not experimentally verified. H…
Origin of trapped intralayer Wannier and charge-transfer excitons in moiré materials
Indrajit Maity, Johannes Lischner, Arash A. Mostofi +1
Moiré materials offer a versatile platform for engineering excitons with unprecedented control, promising next-generation optoelectronic applications. While continuum models are wi…
Magnetic Ordering in Moiré Graphene Multilayers from a Continuum Hartree+U Approach
Christopher T. S. Cheung, Valerio Vitale, Lennart Klebl +5
Recently, symmetry-broken ground states, such as correlated insulating states, magnetic order and superconductivity, have been discovered in twisted bilayer graphene (tBLG) and twi…
