Monolayers of semiconducting transition metal dichalcogenides (TMDs) build a new class of atomically thin two-dimensional materials. They exhibit a remarkably strong Coulomb interaction giving rise to the formation of tightly bound excitons. In addition to regular bright excitonic states, there is also a variety of dark states that cannot be accessed by light due to the required...
Steering the quantum motion of electrons in atoms and molecules by the carrier wave of an intense lightwave lies at the heart of high-harmonic generation and attosecond science [1]. Only recently, lightwave electronics has been extended to solids leading to the observation of dynamical Bloch oscillations [2], high-harmonic generation [3,4], quantum interference [5], and electron–hole...
