Using information markers like entanglement, quantum fluctuations, fidelity susceptibility, participation ration, area in phase space, etc., we realize that higher Landau levels (LL) feel the topological phase transition slightly displaced with regard to the edge state, thus leading to the concept of “higher Landau level TPT”, as “echoes” of the standard edge state TPT. We compute the critical magnetic field and the critical HgTe layer thickness at which these information measures of higher Landau levels undergo a structural change. eng http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Atribución 4.0 Internacional Topological phases 2D Dirac materials Landau levels Information theory Signatures of topological phase transitions in higher Landau levels of HgTe/CdTe quantum wells from an information theory perspective info:eu-repo/semantics/article
