A 3-octave spectral comb is generated in a hydrogen-filled hollow-core photonic-crystal-fiber. The spectrum consists of up to 45 high-order Stokes and anti-Stokes lines generated by coherent ...

Superconducting properties of two bismuthide intermetallic compounds, RbBi2 and CsBi2, were studied by means of experimental measurements and ab initio calculations. We show that in both compounds, ...

A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The ...
