Rare regions, i.e., rare large spatial disorder fluctuations, can dramatically change the properties of a phase transition in a quenched disordered system. In generic classical equilibrium systems, they lead to an essential singularity, the so-called Griffiths singularity, of the free energy in the vicinity of the phase transition. Stronger effects can be observed at zero-temperature quantum phase transitions, at nonequilibrium phase transitions and in systems with correlated disorder. In some… 

Mikrostruktur und elektrischer Transport von Sr 1-x Ca x RuO 3 -Dünnfilmen – Der Weg zur Aufdeckung des Fermiflüssigkeitgrundzustandes in CaRuO 3

Die vorliegende Arbeit hat sich mit dem Materialsystem Sr_(1-x)Ca_(x)RuO_(3) befasst. Das Interesse lag darin, dunne Schichten dieser Materialserie von sehr hoher Qualitat herzustellen, um sie fur

Disorder effects on quantum transport and quantum phase transition in low-dimensional superconducting and topological systems

ABSTRACT Disorder effects inevitably exist in realistic samples, manifesting in various physical properties. In this paper, we review the recent progress in understanding the disorder effects on

Dissecting localization phenomena of dynamical processes on networks

Localization phenomena permeate many branches of physics playing a fundamental role on dynamical processes evolving on heterogeneous networks. These localization analyses are frequently grounded, for

Brain architecture, Griffiths phases, and the stretching of criticality

Stretched critical regions, stemming from structural disorder, yield optimal functionality in a generic way, facilitating the task of self-organizing, adaptive and evolutionary mechanisms selecting for criticality.

Holographic approach to entanglement entropy in disordered systems

We investigate the entanglement entropy of a two-dimensional disordered system holographically. In particular, we study the evolution of the entanglement entropy along renormalization group flows for

Griffiths phases and localization in hierarchical modular networks

While in the small-world networks originally proposed to model brain connectivity, the topological heterogeneities are not strong enough to induce deviations from mean-field behavior, it is shown that a Griffiths phase can emerge under reduced connection probabilities, approaching the percolation threshold.

Griffiths phases and the stretching of criticality in brain networks.

It is shown that, taking into account the complex hierarchical-modular architecture of cortical networks, the singular critical point is replaced by an extended critical-like region that corresponds--in the jargon of statistical mechanics--to a Griffiths phase.

Disorder Effects in Dynamical Restoration of Spontaneously Broken Continuous Symmetry

: We discuss the Euclidean quantum O ( N ) model with N = 2 in a continuous broken symmetry phase. We study the system at low temperatures in the presence of quenched disorder linearly coupled to the



Modern Theory of Critical Phenomena

Non-Fermi-liquid behavior in d - and f -electron metals

A relatively new class of materials has been found in which the basic assumption of Landau Fermi-liquid theory—that at low energies the electrons in a metal should behave essentially as a collection

Statistical Theory of Equations of State and Phase Transitions. I. Theory of Condensation

A theory of equations of state and phase transitions is developed that describes the condensed as well as the gas phases and the transition regions. The thermodynamic properties of an infinite sample

Effect of random defects on the critical behaviour of Ising models

A cumulant expansion is used to calculate the transition temperature of Ising models with random-bond defects. For a concentration, x, of missing interactions in the simple-square Ising model the
