Ref.: Interference-induced terahertz transparency in a semiconductor magneto-plasma. 2009. X. Wang, et al. Nature Physics.
Abstract: Maximum modulation of light transmission occurs when an opaque medium is suddenly made transparent. This phenomenon occurs in atomic and molecular gases through different mechanisms, whereas much room remains for further studies in solids. A plasma is an illustrative system showing opacity for low-frequency light, and light–plasma interaction theory provides a universal framework to describe diverse phenomena including radiation in space plasmas, diagnostics of laboratory plasmas and collective excitations in condensed matter. However, induced transparency in plasmas remains relatively unexplored. Here, we use coherent terahertz magneto-spectroscopy to reveal a thermally and magnetically induced transparency in a semiconductor plasma. A sudden appearance and disappearance of transmission through electron-doped InSb is observed over narrow temperature and magnetic field ranges, owing to coherent interference between left- and right-circularly polarized terahertz eigenmodes. Excellent agreement with theory reveals long-lived coherence of magneto-plasmons and demonstrates the importance of coherent interference in the terahertz regime.









As far as I can tell this was The Spookman’s only appearance.

Scientists have ruled out the possibility that methane is delivered to Mars by meteorites, raising fresh hopes that the gas might be generated by life on the red planetMethane has a short lifetime of just a few hundred years on Mars because it is constantly being depleted by a chemical reaction in the planet's atmosphere, caused by sunlight. Scientists analysing data from telescopic observations and unmanned space missions have discovered that methane on Mars is being constantly replenished by an unknown source and they are keen to uncover how the levels of methane are being topped up.
