Bound states in the continuum in open Aharonov-Bohm rings

Evgeny N. Bulgakov, Konstantin N. Pichugin, Almas F. Sadreev +1

Using formalism of effective Hamiltonian we consider bound states in continuum (BIC). They are those eigen states of non-hermitian effective Hamiltonian which have real eigen value…

Phase rigidity and avoided level crossings in the complex energy plane

E. N. Bulgakov, I. Rotter, A. F. Sadreev

We consider the effective Hamiltonian of an open quantum system, its biorthogonal eigenfunctions $ϕ_{λ}$ and define the value $r_{λ} = (ϕ_{λ} ∣ ϕ_{λ}) / < ϕ_{λ} ∣ ϕ_{λ} >$ that characterizes the phase…
