Explore non-Hermitian models of lattice fermions in this 75-minute physics seminar presented by first-year PhD student Eduard Naichuk, under the supervision of Dr. M.Z. Iorgov from the Institute for Theoretical Physics and Prof. Jeroen van den Brink from Dresden University of Technology. Delve into advanced theoretical physics concepts as part of the "Problems of Theoretical Physics" seminar series designed for students, postgraduate researchers, and scientific staff. Learn about cutting-edge research in theoretical physics, particularly focusing on the mathematical framework of non-Hermitian fermion models in lattice systems.
