Continuously varying critical exponents in long-range quantum spin ladders

open access: yesSciPost Physics, 2023
We investigate the quantum-critical behavior between the rung-singlet phase with hidden string order and the Néel phase with broken SU(2)-symmetry in quantum spin ladders with algebraically decaying unfrustrated long-range Heisenberg interactions.

Critical behavior of hadronic matter: Critical-point exponents [PDF]

open access: yesPhysical Review D, 1979
In statistical physics, the principle of maximum entropy provides conditions on the singular behavior of thermodynamic functions near a critical point, in the form of inequalities for the critical-point exponents. Hadronic matter, when described by an exponentially rising density of states (dual resonance, statistical bootstrap models), exhibits ...

Critical exponents of graphs

open access: yesJournal of Combinatorial Theory, Series A, 2016
The study of entrywise powers of matrices was originated by Loewner in the pursuit of the Bieberbach conjecture. Since the work of FitzGerald and Horn (1977), it is known that $A^{\circ } := (a_{ij}^ )$ is positive semidefinite for every entrywise nonnegative $n \times n$ positive semidefinite matrix $A = (a_{ij})$ if and only if $ $ is a positive ...

Lyapunov exponents, phase transition and chaos bound in Kerr-Newman AdS spacetime

open access: yesNuclear Physics B
In this paper, we investigate Lyapunov exponents associated with chaotic motions of both massless and massive particles in the vicinity of a Kerr-Newman AdS black hole.

Determination of universal critical exponents using Lee-Yang theory

open access: yesPhysical Review Research, 2019
Lee-Yang zeros are points in the complex plane of an external control parameter at which the partition function vanishes for a many-body system of finite size.

Weighted critical exponents of Sobolev-type embeddings for radial functions

open access: yesAdvanced Nonlinear Studies, 2022
In this article, we prove the upper weighted critical exponents for some embeddings from weighted Sobolev spaces of radial functions into weighted Lebesgue spaces. We also consider the lower critical exponent for certain embedding.

Mapped Exponent and Asymptotic Critical Exponent of Words

open access: yes
We study how much injective morphisms can increase the repetitiveness of a given word. This question has a few possible variations depending on the meaning of ``repetitiveness''. We concentrate on fractional exponents of finite words and asymptotic critical exponents of infinite words.

Vulcanization and critical exponents [PDF]

open access: yesJournal de Physique Lettres, 1979
We consider a particular case of vulcanization of polymer chains in a semi dilute solution where a concentration p of vulcanizing agent has been added. This problem is equivalent to the percolation of elements having a functionality f depending both on the length N of the initial chains and on the monomer concentration C. Our approach allows us to take

Critical exponents values for fluids and linear scaled equation of state

open access: yesLittera Scripta, 2011
The behavior of substance in the vicinity of a critical point is the focus of great scienti fic interest. A liquid-liquid phase transition in the supercooled region could influence biochemical or precipitation processes. It is interesting that water in a
