Spectral-Variation Bounds in Hyperbolic Geometry
Oleg Szehr, Alexander Müller-Hermes
We derive new estimates for distances between optimal matchings of eigenvalues of non-normal matrices in terms of the norm of their difference. We introduce and estimate a hyperbol…

Perturbation Theory for Parent Hamiltonians of Matrix Product States
Oleg Szehr, Michael M. Wolf
This article investigates the stability of the ground state subspace of a canonical parent Hamiltonian of a Matrix product state against local perturbations. We prove that the spec…
