title = "√2 step of conductance fluctuations due to the broken time-reversal symmetry in bulk-insulating BiSbTeSe2 devices",
abstract = "We extract the conductance fluctuations and study their magnetic field dependence in the gate-dependent transport of topological electrons in bulk-insulating BiSbTeSe2 devices. With the increasing magnetic field, the conductance fluctuation magnitudes are found to reduce by a ratio of 2 and form a quantized step. The step is observed both in n-type and p-type transport. This is related to the breaking of the time reversal symmetry of three-dimensional topological insulators.",
