Maxwell-Bloch Equations for Two-Level System

Data provided by  National Institute of Standards and Technology

The Maxwell-Bloch equations for a two-level system are solved in a particular case. The example follows that of P. Siddons, "Light propagation through atomic vapours," Journal of Physics B: Atomic, Molecular, and Optical Physics 47, 093001 (2014). In the reference, the optical intensity, population of the upper state and coherence are given for light with a carrier frequency which is on resonance. Here, the same example is worked, but the result is given at intermediate times as well as at the entrance and exit faces as in the example.

Data for "On-grid compressive sampling for spherical field measurements in acoustics" in The Journal of the Acoustical Society of America.

Data provided by  National Institute of Standards and Technology

This dataset contains CSV files for the figures in the paper titled "On-grid compressive sampling for spherical field measurements in acoustics" in The Journal of the Acoustical Society of America. In this paper, we derive a compressive sampling method for spherical harmonic/spherical wavefunction or Wigner D-function series with sparse coefficients. Applications of these sparse expansions include spherical field measurements in acoustics and spherical near-field antenna measurements, to name a couple.

Gas phase fractionation data independent acquisition analysis of a phosphopeptide mixture

Data provided by  National Institute of Standards and Technology

Recent advances in methodology have made phosphopeptide analysis a tractable problem for many proteomicists. There are now a wide variety of robust and inexpensive enrichment strategies to generate phosphoproteomes, while free or inexpensive software tools for quantitation and site localization have simplified phosphoproteome analysis workflow tremendously.

Phase-Resolved Rydberg Atom Field Sensing using Quantum Interferometry

Data provided by  National Institute of Standards and Technology

Although Rydberg atom-based electric field sensing provides key advantages over traditional antenna-based detection, it remains limited by the need for a local oscillator (LO) for low-field and phase resolved detection. In this work, we demonstrate the general applicability of closed-loop quantum interferometric schemes for Rydberg field sensing, which eliminate the need for an LO. We reveal that the quantum-interferometrically defined phase and frequency of our scheme provides an internal reference that enables LO-free full 360 degree-resolved phase sensitivity.

Data for the article " Pseudo-resonant Detection of `Low Frequency' VHF Electric Fields via Rabi Matching with Autler-Townes Splitting in Rydberg Atoms"

Data provided by  National Institute of Standards and Technology

This dataset represents absorption/transmission spectra of resonant probe light power through a Rydberg atom vapor, subject to a simultaneous dressing field and a 'low frequency' field. Data is taken as an oscilloscope average of 5 photodiode voltage traces, with frequency offsets given by a simultaneous reference cell (not included). Some data are given as 2-D arrays, with axes of laser detuning across a waterfall of field strength. Some data represents theory eigen-energies of the system, for comparison. This paper will be submitted to Physical Review Letters.

Data used in writing "Nanoscale bending dynamics in mixed-chain lipid membranes"

Data provided by  National Institute of Standards and Technology

The files include dynamic light scattering (DLS), small angle neutron scattering (SANS), and neutron spin echo spectroscopy (NSE) data that were analyzed in writing the manuscript. The SANS data were collected on the NGB30 SANS and NG3 vSANS instruments at the NIST Center for Neutron Research (NCNR) and have been reduced to absolute intensity using standard procedures. The NSE data were collected on the NGA NSE instrument at the NCNR and have been corrected for the instrument resolution and solvent signal.
