Phase transitions in a non-Hermitian Aubry-André-Harper model

S Longhi - Physical Review B, 2021 - APS
The Aubry-André-Harper model provides a paradigmatic example of aperiodic order in a
one-dimensional lattice displaying a delocalization-localization phase transition at a finite …

Geometrical structure of Laplacian eigenfunctions

DS Grebenkov, BT Nguyen - siam REVIEW, 2013 - SIAM
We summarize the properties of eigenvalues and eigenfunctions of the Laplace operator in
bounded Euclidean domains with Dirichlet, Neumann, or Robin boundary condition. We …

Coexistence of dynamical delocalization and spectral localization through stochastic dissipation
