Fourth-Order Exceptional Points in Correlated Quantum Many-Body Systems
Lorenzo Crippa, Jan Carl Budich, Giorgio Sangiovanni
Non-Hermtian (NH) Hamiltonians effectively describing the physics of dissipative systems have become an important tool with applications ranging from classical meta-materials to qu…
