It provides a comprehensive understanding of the behavior of interacting fermions, which are particles that follow the Pauli exclusion principle. This theory was developed by the physicist Lev Landau in the mid-20th century and has since become a cornerstone in the field of condensed matter physics. Fermi liquid theory is pa..."
