Long-Range Critical Exponents near the Short-Range Crossover. [PDF]
Physical Review Letters, 2017 The d-dimensional long-range Ising model, defined by spin-spin interactions decaying with the distance as the power 1/r^{d+s}, admits a second-order phase transition with continuously varying critical exponents.

Consistent Scaling Exponents at the Deconfined Quantum-Critical Point [PDF]
Chinese Physics Letters, 2020 We report a quantum Monte Carlo study of the phase transition between antiferromagnetic and valence-bond solid ground states in the square-lattice S = 1/2 J–Q model. The critical correlation function of the Q terms gives a scaling dimension corresponding

Tricritical phenomena in holographic chiral phase transitions
Journal of High Energy Physics, 2022 We study critical phenomena at a tricritical point associated with a chiral phase transition which emerges in the D3/D7 model in the presence of a finite baryon number density and an external magnetic field.

Dimensional crossover with a continuum of critical exponents for NLS on doubly periodic metric graphs [PDF]
Analysis & PDE, 2018 We investigate the existence of ground states for the focusing nonlinear Schroedinger equation on a prototypical doubly periodic metric graph. When the nonlinearity power is below 4, ground states exist for every value of the mass, while, for every ...

Derivation of the Critical Point Scaling Hypothesis Using Thermodynamics Only
Entropy, 2020 Based on the foundations of thermodynamics and the equilibrium conditions for the coexistence of two phases in a magnetic Ising-like system, we show, first, that there is a critical point where the isothermal susceptibility diverges and the specific heat

Critical Fractional p-Laplacian System with Negative Exponents
Journal of Function Spaces, 2023 In this paper, we consider a class of fractional p-Laplacian problems with critical and negative exponents. By decomposition of the Nehari manifold, the existence and multiplicity of nontrivial solutions for the above problems are established with ...

Four-loop critical exponents for the Gross-Neveu-Yukawa models [PDF]
, 2017 We study the chiral Ising, the chiral XY and the chiral Heisenberg models at four-loop order with the perturbative renormalization group in $4-\epsilon$ dimensions and compute critical exponents for the Gross-Neveu-Yukawa fixed points to order $\mathcal ...

Restricted Percolation Critical Exponents in High Dimensions [PDF]
Communications on Pure and Applied Mathematics, 2018 Despite great progress in the study of critical percolation on ℤd for d large, properties of critical clusters in high‐dimensional fractional spaces and boxes remain poorly understood, unlike the situation in two dimensions.

Fermion bilinear operator critical exponents at O(1/N2) in the QED-Gross-Neveu universality class [PDF]
Physical Review D, 2018 We use the critical point large $N$ formalism to calculate the critical exponents corresponding to the fermion mass operator and flavour non-singlet fermion bilinear operator in the universality class of Quantum Electrodynamics (QED) coupled to the Gross-
