Fibonacci number systems and the localization criterion in the many-body Aubry-André model
Balázs Hetényi, Balázs Hetényi
We introduce an extension of the Fibonacci number system, we call the fractional Fibonacci number system, which interpolates between the Fibonacci number system (used for natural n…

Disorder averaging in random lattice models with periodic boundary conditions: Application to models with uncorrelated and correlated disorder
Balázs Hetényi, LuÃs Miguel Martelo, András Lászlóffy
Periodic boundary conditions are not always used in the study of disordered systems, but it can be advantageous to apply them to mimick thermodynamically large systems. In this cas…

From generating functions to the geometric Binder cumulant
Balázs Hetényi
We present an overview of the role of generating functions in quantum mechanical contexts, mainly in the modern theory of polarization and in the study of quantum phase transitions…
