New Conception of High Pressure by Wave Functions

Abstract

This article reviews a new quantum mechanical conception of high pressure and some applications in solids, as one of recent developments in marionics. A new force operator in quantum mechanics, which is proposed by the author, is obtained from differentiating of momentum expectation of a quantum particle by time. When this quantum operator is worked to the wavefunctions, the force expectation values, which is called "marion force" after the marionics, can be obtained. The average pressure from this marion force is considered as the new concept of presseure due to the electron momenta in solids. This pressure is in good agreement with the virial pressure which is obtained thermodynamically from average energy of free electron solids. Marionics, which is also new idea of a industrial quantum mechanics or a quantum materials dynamics (QMD), is briefly introduced.
