DMFT reveals the non-Hermitian topology in heavy-fermion systems
Yuki Nagai, Yang Qi, Hiroki Isobe +2
We find that heavy fermion systems can have bulk "Fermi arcs", with the use of the non-Hermitian topological theory. In an interacting electron system, the microscopic many-body Ha…

Non-Hermitian Topological Theory of Finite-Lifetime Quasiparticles: Prediction of Bulk Fermi Arc Due to Exceptional Point
Vladyslav Kozii, Liang Fu
We introduce a topological theory to study quasiparticles in interacting and/or disordered many-body systems, which have a finite lifetime due to inelastic and/or elastic scatterin…
