New Journal of Physics, 2019 We investigate the non-equilibrium dynamics across the miscible–immiscible phase separation in a binary mixture of Bose–Einstein condensates. The excitation spectra reveal that the Landau critical velocity vanishes at the critical point, where the ...

Dimensional Dependence of Critical Exponent of the Anderson Transition in the Orthogonal Universality Class [PDF]
, 2014 We report improved numerical estimates of the critical exponent of the Anderson transition in Anderson’s model of localization in d = 4 and 5 dimensions.

On a singular nonlinear Neumann problem [PDF]
Opuscula Mathematica, 2014 We investigate the solvability of the Neumann problem involving two critical exponents: Sobolev and Hardy-Sobolev. We establish the existence of a solution in three cases: \(\text{(i)}\;\ 2\lt p+1\lt 2^*(s),\) \(\text{(ii)}\;\ p+1=2^*(s)\) and \(\text ...

Physical Review Letters, 2015 We show that the critical exponent of a quantum phase transition in a damped-driven open system is determined by the spectral density function of the reservoir.

New Journal of Physics, 2022 Non-centrosymmetric NdAlGe is considered to be a candidate for magnetic Weyl semimetal in which the Weyl nodes can be moved by magnetization. Clarification of the magnetic structures and couplings in this system is thus crucial to understand its magnetic

Critical Relaxation and Critical Exponents [PDF]
Mod. Phys. Lett. B11, 615-623, 1997, 1998 Dynamic relaxation of the XY model and fully frustrated XY model quenched from an initial ordered state to the critical temperature or below is investigated with Monte Carlo methods. Universal power law scaling behaviour is observed. The dynamic critical exponent $z$ and the static exponent $\eta$ are extracted from the time-dependent Binder cumulant ...

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.

Planar random-cluster model: scaling relations
Forum of Mathematics, Pi, 2022 This paper studies the critical and near-critical regimes of the planar random-cluster model on $\mathbb Z^2$ with cluster-weight $q\in [1,4]$ using novel coupling techniques.

Self-similar solutions to super-critical gKdV [PDF]
Nonlinearity 28 (2015) 545-575, 2014 We construct self similar finite energy solutions to the slightly super-critical generalized KdV equation. These self similar solutions bifurcate as a function of the exponent $p$ from the soliton at the $L^2$ critical exponent.

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 ...
