Strong disorder RG approach of random systems

F Iglói, C Monthus - Physics reports, 2005 - Elsevier
There is a large variety of quantum and classical systems in which the quenched disorder
plays a dominant rôle over quantum, thermal, or stochastic fluctuations: these systems …

[KNYGA][B] Conformal invariance and critical phenomena

Quasiperiodic quantum Ising transitions in 1D

PJD Crowley, A Chandran, CR Laumann - Physical review letters, 2018 - APS
Unlike random potentials, quasiperiodic modulation can induce localization-delocalization
transitions in one dimension. In this Letter, we analyze the implications of this for symmetry …

Exact relationship between the entanglement entropies of XY and quantum Ising chains
