The GW approximation in electronic structure theory has become a widespread tool for
predicting electronic excitations in chemical compounds and materials. In the realm of …

Atomically thin two-dimensional (2D) materials host a rich set of electronic states that differ
substantially from those of their bulk counterparts due to quantum confinement and …

Implementing nonlinear optical components in nanoscale photonic devices is challenged by
phase-matching conditions requiring thicknesses in the order of hundreds of wavelengths …

Abstract Two-dimensional (2D) materials, and the associated van der Waals (vdW)
heterostructures,,,–have provided great flexibility for integrating distinct atomic layers …

We introduce the Computational 2D Materials Database (C2DB), which organises a variety
of structural, thermodynamic, elastic, electronic, magnetic, and optical properties of around …

Abstract Interlayer excitons (ILXs)—electron–hole pairs bound across two atomically thin
layered semiconductors—have emerged as attractive platforms to study exciton …

Abstract yambo is an open source project aimed at studying excited state properties of
condensed matter systems from first principles using many-body methods. As input, yambo …

Interlayer excitons, electron-hole pairs bound across two monolayer van der Waals
semiconductors, offer promising electrical tunability and localizability. Because such …

Ultraflatbands in twisted bilayers of two-dimensional materials have the potential to host
strong correlations, including the Mott-insulating phase at half-filling of the band. Using first …

We report the quasiparticle band gap, excitons, and highly anisotropic optical responses of
few-layer black phosphorous (phosphorene). It is shown that these materials exhibit unique …
