Apparent inconsistency between Streda formula and Hall conductivity in reentrant integer quantum anomalous Hall effect in twisted <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub> <mml:mi>MoTe</mml:mi> <mml:mn>2</mml:mn> </mml:msub
In a system with a gap to charge excitations, there are two ways to measure the Hall conductivity: transport and via the Streda formula. Both measurements should agree, although in a recent experiment in twisted MoTe${}_{2}$ they do not. To resolve this discrepancy, the authors propose here a reentrant bubble/crystal phase. They substantiate this with an analysis of the experimental data. One reentrant phase may be masked by a phase transition, providing insight into the nature of a nearby superconducting phase.
