Slow light with a swept-frequency source

, 2010
We introduce a new concept for stimulated-Brillouin-scattering-based slow light in optical fibers that is applicable for broadly-tunable frequency-swept sources.

Investigating the limits of hard X-ray coherence length measurement employing Young’s double slit experiment

Scientific Reports
Young’s double slit experiment has been the most explored technique to gauge a system’s coherence properties. The limits of this technique in characterizing spatial coherence properties of high emittance, hard X-ray synchrotron sources have been ...

Fermi surface and effective masses in photoemission response of the (Ba1−x K x )Fe2As2 superconductor

Scientific Reports, 2017
The angle-resolved photoemission spectra of the superconductor (Ba1−x K x )Fe2As2 have been investigated accounting coherently for spin-orbit coupling, disorder and electron correlation effects in the valence bands combined with final state, matrix ...

Entanglement and manipulation of the magnetic and spin–orbit order in multiferroic Rashba semiconductors

Nature Communications, 2016
Inα-GeTe, ferroelectric polarization acts to break inversion symmetry of the lattice and induce a strong Rashba-type spin splitting of the electronic band structure.

Surface-electrode ion trap with integrated light source

, 2011
An atomic ion is trapped at the tip of a single-mode optical fiber in a cryogenic (8 K) surface-electrode ion trap. The fiber serves as an integrated source of laser light, which drives the quadrupole qubit transition of $^{88}$Sr$^+$.

Optimization of echo-enabled harmonic generation toward coherent EUV and soft X-ray free-electron laser at NSLS-II

Scientific Reports, 2022
Prebunching via echo-enabled harmonic generation (EEHG) is an efficient way to reduce the radiator length and improve the longitudinal coherence as well as output stability in storage-ring-based free-electron lasers. We propose a conceptual design, which
