Full‐Color Complex‐Amplitude Vectorial Holograms Based on Multi‐Freedom Metasurfaces [PDF]

open access: yesAdvanced Functional Materials, 2019
Phase, polarization, amplitude, and frequency represent the basic dimensions of light, playing crucial roles for both fundamental light–material interactions and all major optical applications.

Iterative quantum amplitude estimation [PDF]

open access: yesnpj Quantum Information, 2019
We introduce a variant of Quantum Amplitude Estimation (QAE), called Iterative QAE (IQAE), which does not rely on Quantum Phase Estimation (QPE) but is only based on Grover’s Algorithm, which reduces the required number of qubits and gates.

A universal broadband and CEP stable seeder for high-power amplifiers [PDF]

open access: yesEPJ Web of Conferences
This work presents a universal seeder architecture based on filamentation and parametric amplification from an Ytterbium pump laser for the generation of pulses with versatile properties in terms of central wavelength, bandwidth, CEP, and contrast for ...

Anti-Series Varactor Network With Improved Linearity Performances in the Presence of Inductive and Capacitive Parasitics

open access: yesIEEE Access, 2021
This paper proposes a varactor-based circuit technique intended for amplitude and phase control, with improved linearity in the presence of parasitic capacitances and parasitic inductances.

Probe of process of multiple-loop chains of parallel and consecutive joints [PDF]

open access: yesE3S Web of Conferences, 2020
The article describes the formation of low-frequency currents in ferromagnetic oscillatory circuits. As a result of parallel and serial connection of multi-loop ferroresonance circuits, the frequencies of harmonics of the second-order amplitude of soft ...

Solving Systems of Random Quadratic Equations via Truncated Amplitude Flow [PDF]

open access: yesIEEE Transactions on Information Theory, 2016
This paper presents a new algorithm, termed truncated amplitude flow (TAF), to recover an unknown vector $ {x}$ from a system of quadratic equations of the form $y_{i}=|\langle {a}_{i}, {x}\rangle |^{2}$ , where $ {a}_{i}$ ’s are given random ...

Amplitude dependence of image quality in atomically-resolved bimodal atomic microscopy [PDF]

open access: yes, 2016
In bimodal FM-AFM, two flexural modes are excited simultaneously. The total vertical oscillation deflection range of the tip is the sum of the peak-to-peak amplitudes of both flexural modes (sum amplitude).

Tropical Amplitudes [PDF]

open access: yesAnnales Henri Poincaré, 2017
In this work, we argue that the α′→0 limit of closed string theory scattering amplitudes is a tropical limit. The motivation is to develop a technology to systematize the extraction of Feynman graphs from string theory amplitudes at higher genus.

Transcritical shallow-water flow past topography: finite-amplitude theory [PDF]

open access: yes, 2009
We consider shallow-water flow past a broad bottom ridge, localized in the flow direction, using the framework of the forced SuGardner (SG) system of equations, with a primary focus on the transcritical regime when the Froude number of the oncoming flow ...

Experimental demonstration of a temporal pulse shaping method based on nonlinear chirp [PDF]

open access: yesEPJ Web of Conferences
We present a general temporal shaping method based on spectral phase-only modulation for ultrafast laser sources. We explain the working principle of this technique and use it experimentally to generate a ramp-shaped pulse at the output of a laser source
