This paper investigates the conditions under which a topological phase transition can occur in decorated lattices, even when time-reversal symmetry is broken by a magnetic field, highlighting the role of chiral symmetry in protecting edge states.
Increasing structural disorder in two-dimensional BixSb1-x alloys can induce a transition from a trivial to a topological insulator state at low disorder, and a subsequent transition to a metallic state at high disorder.
Laterally grown heterostructures of Bi(110) and CrTe2 exhibit robust topological interface states, potentially paving the way for high-density, non-dissipative device applications.
