Dynamical signatures of the vulcanization transition

, 1997
Dynamical properties of vulcanized polymer networks are addressed via a Rouse-type model that incorporates the effect of permanent random crosslinks.

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

IONOSPHERIC STORM OF AUGUST 5–6, 2011: CALCULATION OF MAIN EFFECTS

Radio Physics and Radio Astronomy, 2014
Calculation of dynamic and thermal processes parameters during the severe magnetic storm of August 5–6, 2011 (Kp max=8−) are presented. The magnetic storm was accompanied by negative ionospheric disturbance over Kharkiv which caused a number of changes ...

Enhancement and Speed‐Up of Carrier Dynamics in A Dielectric Nanocavity with Deep Sub‐Wavelength Confinement

Laser &Photonics Reviews, EarlyView.
This work presents the first experimental investigation of ultrafast dynamics in dielectric bowtie nanocavities, featuring deep‐subwavelength mode confinement. Measurements reveal enhanced two‐photon absorption, sub‐picosecond carrier relaxation, and strong pump–probe interactions, demonstrating clear advantages over conventional nanocavities for low ...

Thermal conductivity and air-mediated losses in periodic porous silicon membranes at high temperatures

Nature Communications, 2017
Nanostructuring of silicon allows acoustic phonon engineering, but the mechanism of related thermal transport in these structures is not fully understood.

Incoherent Scatter Radar User Workshop

Eos, Transactions American Geophysical Union, 1984
The incoherent scatter radar technique has developed over the years into one of the most powerful tools for investigating physical processes in the upper atmosphere. The National Science Foundation (NSF) now supports a chain of four incoherent scatter facilities at Sondrestromfjord (Greenland), Millstone Hill (Massachusetts), Arecibo (Puerto Rico), and

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Influence of the Environment Fluctuations on Incoherent Neutron Scattering Functions

, 2001
In extending the conventional dynamic models, we consider a simple model to account for the environment fluctuations of particle atoms in a protein system and derive the elastic incoherent structure factor (EISF) and the incoherent scattering correlation
