Alternate Definitions for qmc

Definition: Quasi-Molecular Crystal (QMC) – A crystal structure where molecules are arranged in a disordered, yet correlated, manner, exhibiting properties intermediate between crystalline and amorphous solids.

Example: Silicon dioxide (SiO₂) forms a QMC, exhibiting some crystalline order but also retaining a degree of disorder due to vibrational motion.

Definition: A class of computational methods that use stochastic sampling and random walks to solve the quantum many-body Schrödinger equation, providing highly accurate predictions of electronic structure and properties.

Example: hard to give an example
