Hydrogen sulfide at high pressure: Change in stoichiometry

Abstract: Hydrogen sulfide $({\mathrm{H}}_{2}\mathrm{S})$ was studied by x-ray synchrotron diffraction and Raman spectroscopy up to 150 GPa at 180--295 K and by quantum-mechanical variable-composition evolutionary simulations. The experiments show that ${\mathrm{H}}_{2}\mathrm{S}$ becomes unstable with respect to formation of compounds with different structure and composition, including Cccm and a body-centered cubic like ($R3m$ or $Im\ensuremath{-}3m$) ${\mathrm{H}}_{3}\mathrm{S}$, the latter one predicted previously to show a record-high superconducting transition temperature, a ${T}_{c}$ of 203 K. These experiments provide experimental ground for understanding of this record-high ${T}_{c}$. The experimental results are supported by theoretical structure searches that suggest the stability of ${\mathrm{H}}_{3}\mathrm{S}, {\mathrm{H}}_{4}{\mathrm{S}}_{3}, {\mathrm{H}}_{5}{\mathrm{S}}_{8}, {\mathrm{H}}_{3}{\mathrm{S}}_{5}$, and $\mathrm{H}{\mathrm{S}}_{2}$ compounds that have not been reported previously at elevated pressures.

Near-Forward Rescattering Photoelectron Holography in Strong-Field Ionization: Extraction of the Phase of the Scattering Amplitude.

Abstract: We revisit the concept of near-forward rescattering strong-field photoelectron holography introduced by Y. Huismans et al. [Science 331, 61 (2011)]. The recently developed adiabatic theory is used to show how the phase of the scattering amplitude for near-forward rescattering of an ionized electron by the parent ion is encoded in and can be read out from the corresponding interference pattern in photoelectron momentum distributions (PEMDs) produced in the ionization of atoms and molecules by intense laser pulses. A procedure to extract the phase is proposed. Its application to PEMDs obtained by solving the time-dependent Schr\"odinger equation for a model atom yields results in good agreement with scattering calculations. This establishes a novel general approach to extracting structural information from strong-field observables capable of providing time-resolved imaging of ultrafast processes.

Ultralow-Loss CMOS Copper Plasmonic Waveguides

Abstract: Surface plasmon polaritons can give a unique opportunity to manipulate light at a scale well below the diffraction limit reducing the size of optical components down to that of nanoelectronic circuits. At the same time, plasmonics is mostly based on noble metals, which are not compatible with microelectronics manufacturing technologies. This prevents plasmonic components from integration with both silicon photonics and silicon microelectronics. Here, we demonstrate ultralow-loss copper plasmonic waveguides fabricated in a simple complementary metal-oxide semiconductor (CMOS) compatible process, which can outperform gold plasmonic waveguides simultaneously providing long (>40 μm) propagation length and deep subwavelength (∼λ2/50, where λ is the free-space wavelength) mode confinement in the telecommunication spectral range. These results create the backbone for the development of a CMOS plasmonic platform and its integration in future electronic chips.
