Long-distance asymptotics of spin-spin correlation functions for the XXZ spin chain

, 2002
We study asymptotic expansions of spin-spin correlation functions for the XXZ Heisenberg chain in the critical regime. We use the fact that the long-distance effects can be described by the Gaussian conformal field theory.

Tensionless strings and the weak gravity conjecture

Journal of High Energy Physics, 2018
We test various conjectures about quantum gravity for six-dimensional string compactifications in the framework of F-theory. Starting with a gauge theory coupled to gravity, we analyze the limit in Kähler moduli space where the gauge coupling tends to ...

High‐strength steel wires containing corrosion pits: stress analysis and critical distance based fatigue life estimation

Fatigue & Fracture of Engineering Materials & Structures, 2019
The present paper deals with the problem of assessing the fatigue lifetime of high-strength steel wires containing corrosion pits, with this investigation being based on a large number of experimental data selected from the technical literature.

Critical percolation on certain non-unimodular graphs [PDF]

, 2005
An important conjecture in percolation theory is that almost surely no infinite cluster exists in critical percolation on any transitive graph for which the critical probability is less than 1. Earlier work has established this for the amenable cases Z^2

"Light from chaos" in two dimensions

, 2008
We perform a Monte-Carlo study of the lattice two-dimensional gauged XY-model. Our results confirm the strong-coupling expansion arguments that for sufficiently small values of the spin-spin coupling the ``gauge symmetry breaking" terms decouple and the ...

Critical Distance Default Values for Structural Steels and a Simple Formulation to Estimate the Apparent Fracture Toughness in U-Notched Conditions

Metals, 2018
The structural integrity assessment of components containing notch-type defects has been the subject of extensive research in the last few decades. The assumption that notches behave as cracks is generally too conservative, making it necessary to develop

Heavy Quark Free Energies and Screening in SU(2) Gauge Theory

, 2002
We investigate the singlet, triplet and colour average heavy quark free energies in SU(2) pure gauge theory at various temperatures T. We focus on the long distance behaviour of the free energies, studying in particular the temperature dependence of the ...

Extreme Type-II Superconductors in a Magnetic Field: A Theory of Critical Fluctuations

, 1998
A theory of critical fluctuations in extreme type-II superconductors subjected to a finite but weak external magnetic field is presented. It is shown that the standard Ginzburg-Landau representation of this problem can be recast, with help of a novel ...

Techno-solutionism a Fact or Farce? A Critical Assessment of GenAI in Open and Distance Education

Journal of Ethics in Higher Education
Techno-solutionism (Ts) amplifies academic integrity issues endemic to using Generative AI in Open and Distance education (ODE). It (Ts) induces in Higher education (HE) the disposition that technology can and should be employed in every aspect of ...

Universal behavior of the Shannon mutual information of critical quantum chains

, 2013
We consider the Shannon mutual information of subsystems of critical quantum chains in their ground states. Our results indicate a universal leading behavior for large subsystem sizes.
