摘要
We discuss for tetrahedratic phases a number of cross-coupling terms not considered be re and we analyse their macroscopic physical consequences. In particular we show that if a tetrahedratic phase is acted on by an electric field that is perpendicular to a temperature gradient, an electric current perpendicular to both forces results. I've also demonstrate that spatial variations of the tetrahedratic order as can arise e.g. near phase transitions, generate reversible stresses and can thus induce flows.
