A bstract In this paper, we classify four-point local gluon S-matrices in arbitrary dimensions. This is along the same lines as [1] where photon and graviton were classified. We do classification explicitly for gauge groups SO( N ) SU( all but our method easily generalizable to other Lie groups. The construction involves combining not-necessarily-permutation-symmetric of photons those adjoint s...

A bstract We derive and study Yangian Ward identities for the infinite class of four-point ladder integrals their Basso-Dixon generalisations. These symmetry equations follow from interpreting respective Feynman as correlation functions in biscalar fishnet theory. Alternatively, presented can be understood anomaly a momentum space conformal symmetry. The take form inhomogeneous extensions parti...

Two- and four-probe electrical measurements on individual conjugated polymer nanowires with different diameters ranging from 20 to 190 nm have been performed to study their conductivity and nanocontact resistance. The two-probe results reveal that all the measured polymer nanowires with different diameters are semiconducting. However, the four-probe results show that the measured polymer nanowi...

magnetic force microscope ( mfm ) is a powerful technique for mapping the magnetic force gradient above the sample surface. herein, single-wall carbon nanotubes (swcnt) were used to fabricate mfm probe by dielectrophoresis method which is a reproducible and cost-effective technique. the effect of induced voltage on the deposition manner of carbon nanotubes (cnt) on the atomic force microscope (...
