The dynamical structure factor is one of the experimental quantities crucial in scrutinizing the validity of the microscopic description of strongly correlated systems. However, despite its long-standing importance, it is exceedingly difficult in gen

Numerical treatment of spin systems with unrestricted spin length S : A functional renormalization group study

Autor: Johannes Reuther, Maria Laura Baez

Publikováno v: Physical Review B. 96

We develop a generalized pseudo-fermion functional renormalization group (PFFRG) approach that can be applied to arbitrary Heisenberg models with spins ranging from the quantum case $S=1/2$ to the classical limit $S\rightarrow\infty$. Within this fra
