Gapless Edge-Modes and Topology in the Qi-Wu-Zhang Model: A Real-Space Analysis
Arjo Dasgupta, Indra Dasgupta
The topological phase transition in the Qi-Wu-Zhang model is studied using a real-space approach. An effective Hamiltonian for the topologically protected edge-modes in a finite-si…

The Anatomy of a Topological Phase Transition in a 2D Chern Insulator
Arjo Dasgupta, Indra Dasgupta
The onset of the topological phase transition in a two-dimensional model for a Chern Insulator, namely the Qi-Wu-Zhang(QWZ) model, is illustrated, with particular emphasis on the a…
