Phase-sensitive avalanche quantum sensing of sub-shot-noise fields
Nikolai D. Klimkin, Misha Ivanov
Avalanche-based detection of small perturbations is commonplace in precision measurement devices from Geiger counters to single-photon avalanche detectors. Here, we expand this pri…
Generation of Stable Peak-Power Similaritons through Gain-Managed Nonlinearity
Haoyuan He, Maksim Kozlov, Alexander Gabriel Loehr +3
Fiber lasers and amplifiers offer attractive alternatives to conventional solid-state systems. However, generation of high-energy ultrashort laser pulses in fibers faces challenges…
Quantum Optics of harmonic generation in the strongly driven Jaynes-Cummings-type system
M Suman, Sili Yi, Maria Chekhova +1
We adapt the Jaynes-Cummings model to study the interface of cavity quantum electrodynamics with strong field and attosecond physics. We show how multi-photon resonances in the Jay…
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 +1
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…
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…
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…
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…
Ultrafast valleytronic logic operations
Francesco Gucci, Eduardo B. Molinero, Mattia Russo +8
Information processing currently reaches speeds as high as 800 GHz. However, the underlying transistor technology is quickly approaching its fundamental limits and further progress…
Revealing the Berry phase under the tunneling barrier
Lior Faeyrman, Eduardo B. Molinero, Roni Weiss +12
In quantum mechanics, a quantum wavepacket may acquire a geometrical phase as it evolves along a cyclic trajectory in parameter space. In condensed matter systems, the Berry phase…
Ultrafast dephasing in solid state high harmonic generation: macroscopic origin revealed by real-space dynamics
