Unveiling chiral states in the XXZ chain: finite-size scaling probing symmetry-enriched c = 1 conformal field theories [PDF]
Journal of High Energy PhysicsAbstract We study the low-energy properties of the one-dimensional spin-1/2 XXZ chain with time-reversal symmetry-breaking pseudo-scalar chiral interaction and propose a phase diagram for the model. In the integrable case of the isotropic Heisenberg model with the chiral interaction, we employ the thermodynamic Bethe ansatz to find

Conformal Symmetry as a Template: Commensurate Scale Relations and Physics Renormalization Schemes
, 1999 Commensurate scale relations are perturbative QCD predictions which relate observable to observable at fixed relative scale, such as the "generalized Crewther relation", which connects the Bjorken and Gross-Llewellyn Smith deep inelastic scattering sum rules to measurements of the e+ e- annihilation cross section.

The star matter composed of nucleons deep inside the compact star like a neutron star is believed to be very dense and various new types of concepts and physical phenomena due to the nontrivial strong correlations are naturally expected. Peudo-conformality in dense star matter has been discussed recently assuming the hidden underlying scale symmetry ...

Nuclear Physics B, 1991 Abstract Conformal invariance at a second-order phase transition yields an exact finite-size scaling theory on a two-dimensional cylindrical geometry. We combine this two-dimensional conformal field theory with a numerical investigation of the deconfinement phase transition of (2 + 1)-dimensional SU(2) lattice gauge theory.

Conformal Symmetry: Finding New Physics in Scale Invariance
, 2016 Modern physics is the study of symmetry. Everything from electromagnetism to the famed Higgs mechanism stems from fundamental symmetries. These have fancy mathematical names and even fancier math behind them, but the basic idea is the same. These are mathematical generalizations of normal transformations such as rotating.

Advanced Engineering Materials, EarlyView.A simulative evaluation of triply periodic minimal surface (TPMS) structures for an elastocaloric application under compressive load is performed. For the evaluation of the structure's performance, surface/volume ratio, generated heat and invested mechanical work are taken into account and are compared to a tube as a reference specimen.

Advanced Engineering Materials, EarlyView.Bimetallic structures of Inconel 718 and CuCrZr are fabricated using the laser powder directed energy deposition method. The study reveals a strong dependence of interface characteristics such as width and interfusion on processing and heat treatment strategies.

Advanced Engineering Materials, EarlyView.This article presents a comprehensive analysis of the intrinsic relationships and applicability of Hill48 yield criterion. The applicability and error evaluation conditions for Hill48 are established based on specific experimental data. A parameter calibration strategy for N‐value based on error minimization is proposed, and the predictive accuracy is ...
