    Continuum mechanics in solids

    Hi all.. I am currently doing some works on the continuum mechanics. And trying to study the macroscopic behavior of solids ( for simplicity, taken homogeneous materials) upon the action of external force ( which is the stress; pressure). How is it possible to account for the changes that can be...

    Choosing appropriate length scale in condensed matter

    Hi.. I was reading some papers on continuum dynamics and its application to various material dynamics. The determination of macroscopic behavior is being studied , considering phononic interactions. As a material consists of phonons of various wavelengths, it is necessary to account for various...

    Antisymmetry of fermions

    I have a doubt regarding the antisymmetry in the wave function of fermions.The antisymmetry is in the complete wave function or it is in the spin?
