Soliton solutions for a quasilinear Schrödinger equation with critical exponent
, 2016 This paper is concerned with the existence of soliton solutions for a quasilinear Schrodinger equation in $R^N$ with critical exponent, which appears from modelling the self-channeling of a high-power ultrashort laser in matter.

New Journal of Physics, 2017 We study the connection between the exponent of the order parameter of the Mott insulator-to-superfluid transition occurring in the two-dimensional Bose–Hubbard model, and the divergence exponents of its one- and two-particle correlation functions.

Existence and nonexistence of solutions for an approximation of the Paneitz problem on spheres
Boundary Value Problems, 2023 This paper is devoted to studying the nonlinear problem with slightly subcritical and supercritical exponents ( S ± ε ) : Δ 2 u − c n Δ u + d n u = K u n + 4 n − 4 ± ε $(S_{\pm \varepsilon}): \Delta ^{2}u-c_{n}\Delta u+d_{n}u = Ku^{ \frac{n+4}{n-4}\pm ...

Critical Exponents for Three-Dimensional Superfluid--Bose-Glass Phase Transition
, 1993 The critical phenomenon of the zero temperature superfluid--Bose-glass phase transition for hard-core bosons on a three-dimensional disordered lattice is studied using a quantum real-space renormalization-group method.

A Bose-Einstein Model of Particle Multiplicity Distributions [PDF]
, 2006 A model of particle production is developed based on a parallel with a theory of Bose-Einstein condensation and similarities with other critical phenomena such as critical opalescence.

Universal critical exponent in class D superconductors
, 2008 We study a physical system consisting of non-interacting quasiparticles in disordered superconductors that have neither time-reversal nor spin-rotation invariance.

The Oslo model, hyperuniformity, and the quenched Edwards-Wilkinson model [PDF]
, 2016 We present simulations of the 1-dimensional Oslo rice pile model in which the critical height at each site is randomly reset after each toppling. We use the fact that the stationary state of this sandpile model is hyperuniform to reach system of sizes $>

On critical exponents for self-similar collapse [PDF]
Journal of High Energy Physics, 2020 Abstract We explore systematically perturbations of self-similar solutions to the Einstein-axion-dilaton system, whose dynamics are invariant under spacetime dilations combined with internal 𝔰𝔩(2, ℝ) transformations. The self-similar solutions capture the enticing behavior “critical” systems on the verge of gravitational collapse ...

Universality versus nonuniversality in asymmetric fluid criticality
Condensed Matter Physics, 2013 Critical phenomena in real fluids demonstrate a combination of universal features caused by the divergence of long-range fluctuations of density and nonuniversal (system-dependent) features associated with specific intermolecular interactions ...
