Fractal characteristics of critical and localized states in incommensurate quantum systems
Incommensurate quantum systems with two competing periodicities exhibit metallic (with Bloch-type extended wave functions), insulating (with exponentially localized wave functions) as well ascritical

Critical behaviour at the transition by breaking of analyticity in the discrete Frenkel-Kontorova model
The authors study numerically the transition by breaking of analyticity which occurs in the incommensurate ground state of the Frenkel-Kontorova model (1938) when the amplitude lambda of its
Phonon localization in one-dimensional quasiperiodic chains.
TLDR
The localization phenomenon apparently is decoupled from the distribution of eigenfrequencies since the spectrum changes from continuous to Cantor-set-like when the inter-action parameters are varied to cross the analyticity–breaking transition.
Critical behaviour at the transition by breaking of analyticity and application to the Devil's staircase
The authors investigate numerically the behaviour of the elastic constant of incommensurate ground states of the discrete Frenkel-Kontorova (FK) model below their transition by breaking of
Renormalization-group theory of the incommensurate pinning transition and threshold dynamics.
TLDR
A renormalization-group approach to incommensurate systems is introduced and a symmetric fixed point of this transformation is found and is seen to determine the critical properties of the depinning transition.
The re-entrant phase diagram of the generalized Harper equation
We study the phase diagram of the tight-binding model for an electron on an anisotropic square lattice with a four-dimensional parameter space defined by two nearest-neighbour and two
