Moiré trapping of quadrupolar excitons in van der Waals trilayers
Indrajit Maity, Arash A. Mostofi, Ãngel 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…
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 w…
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…
Exploring Charge Density Waves in two-dimensional NbSe2 with Machine Learning
Norma Rivano, Francesco Libbi, Chuin Wei Tan +8
Niobium diselenide (NbSe) has garnered significant attention due to the coexistence of superconductivity and charge density waves (CDWs) down to the monolayer limit. However, r…
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…
Atomistic theory of twist-angle dependent intralayer and interlayer exciton properties in twisted bilayer materials
Indrajit Maity, Arash A. Mostofi, Johannes Lischner
Twisted bilayers of two-dimensional (2D) materials have emerged as a highly tunable platform to study and engineer properties of excitons. However, the atomistic description of the…
