Finding critical points using improved scaling Ansaetze

open access: yes, 2015
Analyzing in detail the first corrections to the scaling hypothesis, we develop accelerated methods for the determination of critical points from finite size data.

Deceleration parameter as a unifying criterion for FRW cosmological models at critical points

open access: yesPhysics Letters B
The critical points of dynamical system equations are key in understanding the time evolution of the relevant model-universe. They provide information which help us to rule out those cosmological models which are not able to correctly describe the ...

Dynamics and transport near quantum-critical points

open access: yes, 1997
The physics of non-zero temperature dynamics and transport near quantum-critical points is discussed by a detailed study of the O(N)-symmetric, relativistic, quantum field theory of a N-component scalar field in $d$ spatial dimensions.

On critical points of Blaschke products [PDF]

open access: yes, 2010
We obtain an upper bound for the derivative of a Blaschke product, whose zeros lie in a certain Stolz-type region. We show that the derivative belongs to the space of analytic functions in the unit disk, introduced recently in \cite{FG}.

Coexistence Curve Singularities at Critical End Points

open access: yes, 1997
We report an extensive Monte Carlo study of critical end point behaviour in a symmetrical binary fluid mixture. On the basis of general scaling arguments, singular behaviour is predicted in the diameter of the liquid-gas coexistence curve as the critical

Existence of multiple nontrivial solutions of the nonlinear Schrödinger-Korteweg-de Vries type system

open access: yesAdvances in Nonlinear Analysis, 2021
In this paper we are concerned with the existence, nonexistence and bifurcation of nontrivial solution of the nonlinear Schrödinger-Korteweg-de Vries type system(NLS-NLS-KdV).

Critical fixed points in class D superconductors

open access: yes, 2009
We study in detail a critical line on the phase diagram of the Cho-Fisher network model separating three different phases: metallic and two distinct localized phases with different quantized thermal Hall conductances.

Pairing gaps near ferromagnetic quantum critical points

open access: yes, 2015
We address the quantum-critical behavior of a two-dimensional itinerant ferromagnetic systems described by a spin-fermion model in which fermions interact with close to critical bosonic modes.

Scaling approach to itinerant quantum critical points

open access: yes, 2003
Based on phase space arguments, we develop a simple approach to metallic quantum critical points, designed to study the problem without integrating the fermions out of the partition function.
