Topological Surface States in Dense Solid Hydrogen.

Metallization of dense hydrogen and associated possible high-temperature superconductivity represents one of the key problems of physics. Recent theoretical studies indicate that before becoming a good metal, compressed solid hydrogen passes through a semimetallic stage. We show that such semimetallic phases predicted to be the most stable at multimegabar (∼300  GPa) pressures are not conventio...

Bound exciton and free exciton states in GaSe thin slab

The photoluminescence (PL) and absorption experiments have been performed in GaSe slab with incident light polarized perpendicular to c-axis of sample at 10 K. An obvious energy difference of about 34 meV between exciton absorption peak and PL peak (the highest energy peak) is observed. By studying the temperature dependence of PL and absorption spectra, we attribute it to energy difference bet...

Plasmon-Frenkel-exciton in a clustered solid

The standard theory of the Frenkel exciton (a small radius exciton) is applied to a fullerene 2D solid. It is the dipole collective electron excitation of a single cluster which forms the delocalized plasmon-Frenkel-exciton (PFE) in a crystal. The PFE retarded interaction is taken into account. We present transverse PFE-polariton dispersion curves along with the Coulomb problem solution for lon...

Hydrogen Utilization Potential in Subsurface Sediments

Subsurface microbial communities undertake many terminal electron-accepting processes, often simultaneously. Using a tritium-based assay, we measured the potential hydrogen oxidation catalyzed by hydrogenase enzymes in several subsurface sedimentary environments (Lake Van, Barents Sea, Equatorial Pacific, and Gulf of Mexico) with different predominant electron-acceptors. Hydrogenases constitute...

Statistics of Exciton Emission in a Semiconductor Microcavity: Detuning and Exciton-Exciton Effects

We consider the interaction of quantum light with an ideal semiconductor microcavity. We investigate photon statistics in different conditions and the presence of detuning and exciton-exciton interaction. We show that in the resonant interaction and absence of the exciton-exciton interaction, the state of the whole system can be considered as   coherent state. According to our results, it turns...
