Insufficient availability of weather stations recording air temperature is a common problem in many alpine regions. The low station density combined with the high variability of air temperature means that interpolated fields based on simple or more complex interpolation techniques are unlikely to be representative of the real patterns of air temperature. In this study, a novel method was developed...
Attosecond polarization spectroscopy is a new experimental technique resolving the nonlinear polarization and energy-transfer induced by visible few-cycle strong fields in solids. It reveals the intensity dependent response time of the system with attosecond resolution.
A multitude of physical effects have been proposed to determine the photoemission delay between core and valence electrons in tungsten. We present selected streaking experiments that clarify its origins.
Highly nonlinear, but reversible changes in the refractive index of SiO2 induced by strong near-infrared light fields are probed with wave-cycle resolved optical reflectivity and attosecond streaking characterization of the transmitted field.
