Geometric bound on structure factor

Yugo Onishi, Alexander Avdoshkin, Liang Fu

We show that a quadratic form of quantum geometric tensor in $k$ -space sets a bound on the $q^{4}$ term in the static structure factor $S (q)$ at small $q$ . Bands that saturate…

Geometry of degenerate quantum states, configurations of $m$ -planes and invariants on complex Grassmannians

Alexander Avdoshkin

Understanding the geometric information contained in quantum states is valuable in various branches of physics, particularly in solid-state physics when Bloch states play a crucial…
