High-resolution, large field-of-view label-free imaging via aberration-corrected, closed-form complex field reconstruction

Posted by klaurent Caltech

Kavli Affiliate: Changhuei Yang | First 5 Authors: Ruizhi Cao, Cheng Shen, Changhuei Yang, , | Summary: Computational imaging methods empower modern microscopy with the ability of producing high-resolution, large field-of-view, aberration-free images. One of the dominant computational label-free imaging methods, Fourier ptychographic microscopy (FPM), effectively increases the spatial-bandwidth product of conventional microscopy by using […]

Fermionic quantum computation with Cooper pair splitters

Posted by dbos Delft

Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Antonio Manesco, Juan Daniel Torres Luna, Sebastian Miles, Michael Wimmer | Summary: We propose a practical implementation of a universal quantum computer that uses local fermionic modes (LFM) rather than qubits. Our design consists of quantum dots tunnel coupled by a hybrid superconducting island together […]

Phonon-Dressed Third-Harmonic Generation in Diamond

Posted by dbos Cornell

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses, , | Summary: We demonstrate a strong, elastic, frequency-upshifting optical polarizability that accompanies sum-frequency driving of Raman phonons and two-photon absorption, extending the duality of structural and optical property modification recently observed in light-driven phononics. The effect, phonon-dressed third-harmonic generation (THG), […]

Phonon-Mediated Third-Harmonic Generation in Diamond

Posted by dbos Cornell

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses, , | Summary: We observe strongly anisotropic third-harmonic generation mediated by resonant sum-frequency driving of Raman phonons with THz light, extending light-induced dual control of structural and optical properties in solids. Either strong enhancement or strong suppression of the third harmonic […]

Determining Quasi-Equilibrium Electron and Hole Distributions from Plasmonic Photocatalysts using Photomodulated X-ray Absorption Spectroscopy

Posted by klaurent Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Levi D. Palmer, Wonseok Lee, Chung Li Dong, Ru-Shi Liu, Nianqiang Wu | Summary: Most photocatalytic and photovoltaic devices operate under broadband, constant illumination. Electron and hole dynamics in these devices, however, are usually measured using ultrafast pulsed lasers in a narrow wavelength range. In this […]
