Critical exponents for diluted resistor networks [PDF]
Physical Review E, 1999 An approach by Stephen is used to investigate the critical properties of randomly diluted resistor networks near the percolation threshold by means of renormalized field theory. We reformulate an existing field theory by Harris and Lubensky. By a decomposition of the principal Feynman diagrams we obtain a type of diagrams which again can be interpreted

Meson excitation time as a probe of holographic critical point
European Physical Journal C: Particles and Fields, 2023 We study the time evolution of expectation value of Wilson loop as a non-local observable in a strongly coupled field theory with a critical point at finite temperature and nonzero chemical potential, which is dual to an asymptotically AdS charged black ...

Dynamical critical exponent of the Jaynes-Cummings-Hubbard model [PDF]
, 2011 An array of high-Q electromagnetic resonators coupled to qubits gives rise to the Jaynes-Cummings-Hubbard model describing a superfluid to Mott-insulator transition of lattice polaritons.

Accurate estimate of the critical exponent nu for self-avoiding walks via a fast implementation of the pivot algorithm. [PDF]
Physical Review Letters, 2010 We introduce a fast implementation of the pivot algorithm for self-avoiding walks, which we use to obtain large samples of walks on the cubic lattice of up to 33x10{6} steps. Consequently the critical exponent nu for three-dimensional self-avoiding walks

Nonlinear response for external field and perturbation in the Vlasov system [PDF]
, 2014 A nonlinear response theory is provided by use of the transient linearization method in the spatially one-dimensional Vlasov systems. The theory inclusively gives responses to external fields and to perturbations for initial stationary states, and is ...

AxiomsIn this article, we consider the singular p-biharmonic problem involving Hardy potential and critical Hardy–Sobolev exponent. Firstly, we study the existence of ground state solutions by using the minimization method on the associated Nehari manifold ...

Topological quantum number and critical exponent from conductance fluctuations at the quantum Hall plateau transition [PDF]
, 2011 The conductance of a two-dimensional electron gas at the transition from one quantum Hall plateau to the next has sample-specific fluctuations as a function of magnetic field and Fermi energy.

Finite-size scaling at the jamming transition: corrections to scaling and the correlation-length critical exponent. [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2010 We carry out a finite-size scaling analysis of the jamming transition in frictionless bidisperse soft core disks in two dimensions. We consider two different jamming protocols: (i) quench from random initial positions and (ii) quasistatic shearing.

Non Markovian persistence in the diluted Ising model at criticality
, 2005 We investigate global persistence properties for the non-equilibrium critical dynamics of the randomly diluted Ising model. The disorder averaged persistence probability $\bar{{P}_c}(t)$ of the global magnetization is found to decay algebraically with an

Solutions of p(x)-Laplacian equations with critical exponent and perturbations in R^N
Electronic Journal of Differential Equations, 2012 Based on the theory of variable exponent Sobolev spaces, we study a class of $p(x)$-Laplacian equations in $mathbb{R}^{N}$ involving the critical exponent.
