abstract = {We analyze the structure of low energy Hamiltonian eigenstates in zincblende heterostructures
(like HgTe/CdTe quantum wells) near the gamma point, under magnetic
fields, to characterize topological phase transitions (TPT) under an information-theoretic
perspective. 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 |n| > 0 TPT’’, as
‘‘echoes’’ of the standard edge state n = 0 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.},
