Two state model for critical points and the negative slope of the melting-curve
Graeme J. Ackland, Hongxiang Zong, Victor Naden Robinson Sandro Scandolo +1
We present a thermodynamic model which explains the presence of a negative slope in the melt curve, as observed in systems as diverse as the alkali metals and molecular hydrogen at…

On stable H-C-N-O compounds at high pressure
Lewis J. Conway, Chris J. Pickard, Andreas Hermann
The make-up of the outer planets, and many of their moons, are dominated by matter from the H-C-N-O chemical space, commonly assumed to originate from mixtures of hydrogen and the…

Changes of Fermi Surface Topology due to the Rhombohedral Distortion in SnTe
Christopher D. O'Neill, Oliver J. Clark, Harry D. J. Keen +7
Stoichiometric SnTe is theoretically a small gap semiconductor that undergoes a ferroelectric distortion on cooling. In reality however, crystals are always non-stoichiometric and…
