Recently, the celebrated Rytova-Keldysh potential has been widely used to describe the
Coulomb interaction of few-body complexes in monolayer transition-metal dichalcogenides …

The electronic and optical properties of monolayer transition-metal dichalcogenides (TMDs)
and van der Waals heterostructures are strongly subject to their dielectric environment. In …

The optical properties of atomically thin transition metal dichalcogenide (TMDC)
semiconductors are shaped by the emergence of correlated many-body complexes due to …

We report a rare atom-like interaction between excitons in monolayer WS2, measured using
ultrafast absorption spectroscopy. At increasing excitation density, the exciton resonance …

We investigate the effects of external dielectric screening on the electronic dispersion and
the band gap in the atomically thin, quasi-two-dimensional (2D) semiconductor WS 2 using …

Over the past two decades, following the early developments on maximally localized
Wannier functions, an ecosystem of electronic-structure simulation techniques and software …

Plasmons depend strongly on dimensionality: while plasmons in three-dimensional systems
start with finite energy at wavevector q= 0, plasmons in traditional two-dimensional (2D) …

Coulomb interactions in atomically thin materials are remarkably sensitive to variations in
the dielectric screening of the environment, which can be used to control exotic quantum …
