Fractality of Hofstadter Butterfly in Specific Heat Oscillation
We calculate thermodynamical properties of the Hofstadter model using a recently
developed quantum transfer matrix method. We find intrinsic oscillation features in specific
heat that manifest the fractal structure of the Hofstadter butterfly. We also propose
experimental approaches which use specific heat as an access to detect the Hofstadter
butterfly.
