Abstract

<p>The Lieb-Schultz-Mattis theorem is a powerful theorem that puts nonperturbative restriction on possible phases of quantum many-body systems based on the filling fraction. We review recent extensions of the theorem to the systems with nonsymmorphic space groups and /or strong spin–orbit interactions, emphasizing their applications in searching for Dirac / Weyl semimetals and quantum spin liquids.</p>
