Luttinger's theorem at the core of topological matter

In 1960, Joaquin Luttinger introduced a universal statement that relates the total number of particles that a system can accommodate to its behavior under low-energy excitations. While Luttinger's theorem is readily verified in systems of independent particles, it also holds true … | Continue reading
