The Pomeranchuk instability is an instability in the shape of the Fermi surface of a material with interacting fermions, causing Landau’s Fermi liquid theory to break down. It occurs when a Landau parameter in Fermi liquid theory has a sufficiently negative value, causing deformations of the Fermi surface to be … See more In a 3D isotropic Fermi liquid, consider small density fluctuations $${\textstyle \delta n_{k}=\Theta ( k -p_{\mathrm {F} })-\Theta ( k -p_{\mathrm {F} }'({\hat {k}}))}$$ around the Fermi momentum $${\textstyle p_{\mathrm {F} }}$$, … See more • Kohn anomaly • Pomeranchuk's theorem • Lindhard theory See more The Pomeranchuk instability manifests in the dispersion relation for the zeroth sound, which describes how the localized fluctuations of the momentum density function $${\textstyle \delta n_{k}}$$ propagate through space and time.
