Exact description of coalescing eigenstates in open quantum systems in terms of microscopic Hamiltonian dynamics
Kazuki Kanki, Savannah Garmon, Satoshi Tanaka +1
At the exceptional point where two eigenstates coalesce in open quantum systems, the usual diagonalization scheme breaks down and the Hamiltonian can only be reduced to Jordan bloc…
