= Peierls substitution
{wiki=Peierls_substitution}
Peierls substitution is a technique used in solid-state physics and condensed matter physics to incorporate the effects of an external magnetic field into the Hamiltonian of a system of charged particles, such as electrons in a crystal lattice. It provides a way to modify the tight-binding model or other lattice models to include the influence of magnetic fields through changes in the hopping parameters or phase factors associated with electron movements.
