Entropy-driven transitions between extended integer and fractional quantum Hall regimes
The analysis investigates how entropy from soft modes drives thermal transitions between extended integer quantum Hall (IQH) and fractional quantum Hall (FQH) states in moiré rhombohedral graphene. It proposes that a soft magnetoroton mode in the FQH state provides the bulk mechanism for this observed thermal evolution, suggesting that as temperature increases, the system favors the fractional regime.
