What Does PSRG Stand For?

PSRG stands for Position Space Renormalization Group For D Of States Calcns

The Position Space Renormalization Group (PSRG) is a theoretical framework used for calculating properties of quantum systems across various dimensions. It focuses on the renormalization techniques applied in position space, facilitating the analysis of many-body interactions and state configurations. PSRG effectively captures the essential low-energy physics while systematically eliminating high-energy degrees of freedom, thus enabling accurate predictions of physical observables in condensed matter and statistical mechanics.
