Role of friction in multidefect ordering
, 2020 We use continuum simulations to study the impact of friction on the ordering of defects in an active nematic. Even in a frictionless system, +1/2 defects tend to align side-by-side and orient antiparallel reflecting their propensity to form, and ...

Nanoscale gold pillars strengthened through dislocation starvation [PDF]
, 2006 It has been known for more than half a century that crystals can be made stronger by introducing defects into them, i.e., by strain-hardening. As the number of defects increases, their movement and multiplication is impeded, thus strengthening the ...

Topological defects of N\'eel order and Kondo singlet formation for Kondo-Heisenberg model on a honeycomb lattice [PDF]
, 2013 Heavy fermion systems represent a prototypical setting to study magnetic quantum phase transitions. A particular focus has been on the physics of Kondo destruction, which captures quantum criticality beyond the Landau framework of order-parameter ...

, 2010 We study k-defects - topological defects in theories with more than two derivatives and second-order equations of motion - and describe some striking ways in which these defects both resemble and differ from their analogues in canonical scalar field ...

The changing epidemiology of syndactyly in Chinese newborns: a nationwide surveillance-based study
BMC Pregnancy and Childbirth, 2023 Background Little is known about the epidemiologic features of syndactyly (SD) in Chinese newborns. Methods Using 2007–2019 data from the Chinese Birth Defects Monitoring Network, we conducted a prevalence analysis on overall, isolated and associated ...

Native defects in ultra-high vacuum grown graphene islands on Cu(111)
, 2015 We present a scanning tunneling microscopy (STM) study of native defects in graphene islands grown by ultra-high vacuum (UHV) decomposition of ethylene on Cu(111).

Nuclear Physics B, 2012 We discuss some general properties of "defect branes", i.e. branes of co-dimension two, in (toroidally compactified) IIA/IIB string theory. In particular, we give a full classification of the supersymmetric defect branes in dimensions 2 < D < 11 as well as their higher-dimensionalstring and M-theory origin as branes and a set of "generalized ...

Algebraic approach to multiple defects on the line and application to Casimir force
, 2007 An algebraic framework for quantization in presence of arbitrary number of point-like defects on the line is developed. We consider a scalar field which interacts with the defects and freely propagates away of them.
