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…
Coherent control of chirality in Weyl semimetals
Amar Bharti, Margarita Khokhlova, Misha Ivanov +1
Weyl fermions in inversion-symmetric Weyl semimetals occur in pairs of opposite chirality, leading to symmetric optical responses under circularly-polarised light and a vanishing n…
Sub-cycle field-driven dynamical Berry phase in solids
Lior Faeyrman, Jianing Zhang, Misha Ivanov +3
In quantum mechanics, a wavepacket acquires a geometric phase, known as the Berry phase, as it evolves along a closed trajectory in parameter space. In condensed matter systems, th…
Spontaneous symmetry breaking in nonlinear superradiance
Nikolai D. Klimkin, Misha Ivanov
Creation and manipulation of non-classical states of light is rapidly becoming the focus of modern attosecond science. Here, we demonstrate numerically how interaction with such st…
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…
