Universality and quantum criticality in quasiperiodic spin chains

Quasiperiodic systems share features with disordered models but their underlying determinism give them distinct behaviour. Here the authors study the critical behaviour of quasiperiodic spin models and show that the renormalization group fixed points have couplings given by self-similar discrete seq...
