Topology and edge modes in quantum critical chains
Ruben Verresen, Nick G. Jones, Frank Pollmann
We show that topology can protect exponentially localized, zero energy edge modes at critical points between one-dimensional symmetry protected topological phases. This is possible…
One-Dimensional Symmetry Protected Topological Phases and their Transitions
Ruben Verresen, Roderich Moessner, Frank Pollmann
We present a unified perspective on symmetry protected topological (SPT) phases in one dimension and address the open question of what characterizes their phase transitions. In the…
Dynamics of the Kitaev-Heisenberg Model
Matthias Gohlke, Ruben Verresen, Roderich Moessner +1
We introduce a matrix-product state based method to efficiently obtain dynamical response functions for two-dimensional microscopic Hamiltonians, which we apply to different phases…
