PLANAR ISING MODEL AT CRITICALITY: STATE-OF-THE-ART AND PERSPECTIVES [PDF]

open access: yesInternational Congress of Mathematicans, 2017
In this essay, we briefly discuss recent developments, started a decade ago in the seminal work of Smirnov and continued by a number of authors, centered around the conformal invariance of the critical planar Ising model on $\mathbb{Z}^2$ and, more ...

A Metamaterial Analog of the Ising Model [PDF]

open access: yesAdvanced Materials, 2018
AbstractThe interaction between microscopic particles is always a fascinating and intriguing area of science. Direct interrogation of such interactions is often difficult. Structured electromagnetic systems offer a rich toolkit for mimicking and reproducing the key dynamics that govern the microscopic interactions, and thus provides an avenue to ...

Global quantum correlations in finite-size spin chains

open access: yesNew Journal of Physics, 2013
We perform an extensive study of the properties of global quantum correlations in finite-size one-dimensional quantum spin models at finite temperature. By adopting a recently proposed measure for global quantum correlations (Rulli and Sarandy 2011 Phys.

Construction of p-Adic Gibbs Measure for p-Adic λ-Ising Model [PDF]

open access: yesEurasian Journal of Science and Engineering, 2017
In this work we establish the existence of the p-adic Gibbs measure for the p-adic λ-Ising model on the Cayley tree of order two. In the previous studies, p-adic Ising model and p-adic λ-model were distinctly studied in many papers with the various ...

Metastability in an open quantum Ising model. [PDF]

open access: yesPhysical Review E, 2016
We apply a recently developed theory for metastability in open quantum systems to a one-dimensional dissipative quantum Ising model. Earlier results suggest this model features either a nonequilibrium phase transition or a smooth but sharp crossover ...

Revising the universality class of the four-dimensional Ising model

open access: yesNuclear Physics B, 2023
The aim of this paper is to determine the behavior of the specific heat of the 4-dimensional Ising model in a region around the critical temperature, and via that determine if the Ising model and the ϕ4-model belong to the same universality class in ...

Determination of paramagnetic and ferromagnetic phases of an Ising model on a third-order Cayley tree [PDF]

open access: yesCondensed Matter Physics, 2021
In this present paper, the recurrence equations of an Ising model with three coupling constants on a third-order Cayley tree are obtained. Paramagnetic and ferromagnetic phases associated with the Ising model are characterized.

Gaps in the Heisenberg-Ising model [PDF]

open access: yesPhysical Review B, 1995
We report on the closing of gaps in the ground state of the critical Heisenberg-Ising chain at momentum $ $. For half-filling, the gap closes at special values of the anisotropy $ = \cos( /Q)$, $Q$ integer. We explain this behavior with the help of the Bethe Ansatz and show that the gap scales as a power of the system size with variable exponent ...

Dimers and the Ising model [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2008
We present a innovative relationship between ground states of the Ising model and dimer coverings which sheds new light on the Ising Models with highly degenerated ground states and enables one to construct such models. Thanks to this relationship we also find the generating function for dimers as the appropriate limit of the free energy per spin for ...
