Universal constraints for conformal line defects
Physical Review DWe present a novel framework for deriving integral constraints for correlators on conformal line defects. These constraints emerge from the nonlinearly realized ambient-space conformal symmetry. To validate our approach, we examine several examples and compare them against existing data for the four-point function of the displacement operator ...

Topological Line Defect Waveguide
Advanced Optical MaterialsAbstractPhotonic crystal line‐defect waveguides featuring bandgap confined low loss waveguiding are hindered by high bending losses. Although vortex‐mediated topological modes can facilitate seamless propagation through sharp bends, studies of topological transport have primarily focused on interfacial waveguides. In this work, we unveil the prevalence

Fluctuations of topological disclination lines in nematics: renormalization of the string model
, 2004 The fluctuation eigenmode problem of the nematic topological disclination line with strength $\pm 1/2$ is solved for the complete nematic tensor order parameter. The line tension concept of a defect line is assessed, the line tension is properly defined.

Finite element approximation of the fields of bulk and interfacial line defects [PDF]
, 2017 A generalized disclination (g.disclination) theory [AF15] has been recently introduced that goes beyond treating standard translational and rotational Volterra defects in a continuously distributed defects approach; it is capable of treating the ...

Simulation of lattice statistical models with defects: Critical Casimir Effect
EPJ Web of Conferences, 2018 The influence of lattice structure defects on phase transition phenomena was studied in framework of 2D spin model. Effective mass of defect was proposed for investigation of conformal properties of the model at critical point.

Mossbauer effect and its applications in materials research [PDF]
, 1972 It is generally recognized that in any well behaved metal fatigue failure, the following sequence of events occurs. The application of stress causes the movement of defects already present in the specimen, besides producing new defects.
