recent experimental data on space - and time - like form factors of the nucleon are analyzed in terms of a two - component model with a quark - like intrinsics structure and a meson cloud. a good overall agreement is found for all electromagnetic form factors with the exception of the neutron magnetic form factor in th... | arxiv:nucl-th/0502050 |
assuming that the near horizon geometry of the black hole solution of the gravity dual to the abjm model, in the presence of a coupling between the weyl tensor and the field strength, is $ ads _ { 2 } \ times s ^ { 2 } $, we compute sen ' s entropy function for this theory. by extremizing the entropy function we write ... | arxiv:1502.05949 |
the imaginary poynting momentum ( ipm ) of light has been captivated an unusual origin of optomechanical effects on dipolar magnetoelectric particles, but yet observed in experiments. here, we report, for the very first time, a whole family of high - order ipm forces for not only magnetoelectric but also generic mie pa... | arxiv:2206.03153 |
