The fascinating electronic and optoelectronic properties of freestanding graphene and the
possible inclusion of novel two-dimensional (2D) systems in silicon-based electronics have …

The electronic properties of graphene can give rise to a range of nonlinear optical
responses. One of the most desirable nonlinear optical processes is high-harmonic …

High-harmonic generation (HHG) in solids is an emerging method to probe ultrafast electron
dynamics in solids at attosecond time scale. In this work, we study HHG from monolayer and …

A first on ultrafast phenomena in carbon nanostructures like graphene, the most promising
candidate for revolutionizing information technology and communication The book …

We theoretically investigate mechanisms of higher-order harmonic generation in solid-state
materials under a high-intensity ac electric field. A new theoretical framework presented in …

While various excitonic insulators have been studied in the literature, due to the perceived
too-small spin splitting, spin-triplet excitonic insulator is rare. In two-dimensional systems …

Driven and non‐equilibrium quantum states of matter have attracted growing interest in both
theoretical and experimental studies in condensed matter physics. Recent progress in …

A self-consistent scheme for the calculations of the interacting ground state and the near
band-gap optical spectra of mono-and multilayer transition-metal-dichalcogenide systems is …

We present the results of pump–probe experiments on multilayer graphene samples
performed in a wide spectral range, namely from the near infrared (photon energy 1.5 eV) to …

Generation of high harmonics in a monolayer graphene initiated by a strong coherent
radiation field, taking into account electron-electron Coulomb interaction, is investigated. A …
