Eigenvalue problem meets Sierpinski triangle: computing the spectrum of a non-self-adjoint random operator

Simon Chandler-Wilde, Ratchanikorn Chonchaiya, Marko Lindner

The purpose of this paper is to prove that the spectrum of the non-self-adjoint one-particle Hamiltonian proposed by J. Feinberg and A. Zee (Phys. Rev. E 59 (1999), 6433--6443) has…
