Extreme Ultrafast Dynamics of the Refractive Index in Transparent Conductive Oxides: Theory and Experiment
Noa Konforty, Graham G. Brown, Ohad Segal +5
Recent experiments in transparent conductive oxides (TCOs) have revealed light-induced order-unity variations in the refractive index occurring at extreme time scales, as short as…
Valley polarization driven by two-color circular fields: a rotating frame and strong-field perspective
Rui E. F. Silva, Olga Smirnova, Misha Ivanov +2
Valley polarization in hexagonal materials driven by the form of the lightwave and its orientation relative to the lattice, rather than solely by the helicity of the driver, has re…
Attosecond quantum spectroscopy with entangled photon pairs
Zijian Lyu, Fengxiao Sun, Sili Yi +6
Bright squeezed light from parametric down-conversion in the infrared (IR) frequency range has triggered the emergence of attosecond quantum optics -- a new research field at the i…
Attosecond-resolved quantum fluctuations of light and matter
Matan Even Tzur, Chen Mor, Noa Yaffe +10
Until recently, attosecond optical spectroscopy and quantum optics evolved along non-overlapping directions. In attosecond science, attosecond pulses have been regarded as classica…
Unambiguous discrimination of high harmonic generation mechanisms in solids
Graham G. Brown, Rui E. F. Silva, Ãlvaro Jiménez-Galán +2
Using real-space view of high harmonic generation (HHG) in solids, we develop a physically transparent and gauge-invariant approach for distinguishing intraband and interband HHG m…
Semiconductor Wannier equations: a real-time, real-space approach to the nonlinear optical response in crystals (ATATA)
Eduardo B. Molinero, Bruno Amorim, Misha Ivanov +6
We develop the semiconductor Wannier equations (SWEs), a real-time, real-space formulation of ultrafast light-matter dynamics in crystals, by deriving the equations of motion for t…
