Since the pioneering works by Landau, Zener, Stückelberg, and Majorana (LZSM), it has
been known that driving a quantum two-level system results in tunneling between its states …

Petahertz, or lightwave, electronics uses tailored optical waveforms to control charge
carriers in an electronic circuit at petahertz frequencies. This may enable faster processing …

Since 2001 and the first demonstrations of the feasibility of generating and measuring
attosecond light pulses, attosecond science has developed into a very active and quickly …

Light-driven electronic excitation is a cornerstone for energy and information transfer. In the
interaction of intense and ultrafast light fields with solids, electrons may be excited …

The injection of directional currents in solids with strong optical fields has attracted
tremendous attention as a route to realize ultrafast electronics based on the quantum …

We investigate theoretically and numerically the light-matter interaction in a two-band
system (TBS) as a model system for excitation in a solid-state band structure. We identify five …

Photoconductive field sampling enables petahertz-domain optoelectronic applications that
advance our understanding of light-matter interaction. Despite the growing importance of …

We perform nonperturbative calculations of light field induced current in twisted bilayer
graphene (tBLG) irradiated by a circularly polarized (CP) few-cycle laser pulse. The strong …

Controlling electrons with ever-greater precision is central to both classical and quantum
electronics. Since the invention of the laser, virtually every property of coherent light has …

Raman spectroscopy is a widely used method for the analysis of various samples, including
carbon-based materials. This study aimed to identify the number of layers and defects in …
