Rare region effects at classical, quantum and nonequilibrium phase transitions

T Vojta - Journal of Physics A: Mathematical and General, 2006 - iopscience.iop.org
Rare regions, ie, rare large spatial disorder fluctuations, can dramatically change the
properties of a phase transition in a quenched disordered system. In generic classical …

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 …

Random free-fermion quantum spin chain with multispin interactions

FC Alcaraz, JA Hoyos, RA Pimenta - Physical Review B, 2023 - APS
We study the effects of quenched disorder in a class of quantum chains with (p+ 1)-multispin
interactions exhibiting a free fermionic spectrum, paying special attention to the case p= 2 …

Complex quantum network models from spin clusters

RTC Chepuri, IA Kovács - Communications Physics, 2023 - nature.com

Renormalization group study of the two-dimensional random transverse-field Ising model

IA Kovács, F Iglói - Physical Review B—Condensed Matter and Materials …, 2010 - APS
The infinite-disorder fixed point of the random transverse-field Ising model is expected to
control the critical behavior of a large class of random quantum and stochastic systems …

Absorbing state phase transitions with quenched disorder

J Hooyberghs, F Iglói, C Vanderzande - Physical Review E—Statistical …, 2004 - APS
Quenched disorder—in the sense of the Harris criterion—is generally a relevant perturbation
at an absorbing state phase transition point. Here using a strong disorder renormalization …
