Quantum mechanics discovers unusual crystal structure in calcium metal under high pressure
A Swedish research team led by Professor Rajeev Ahuja and Prof. H.K. Mao from USA have used theoretical calculations to study high pressure behaviour of calcium and predicted a new type of incommensurate phase. This is the first time that such phase is discovered from theory. The findings are being published in this week's Net edition of Proceedings of the National Academy of Science, USA.
