    “…The problem is considered in the framework of integrable turbulence in which solitons play a key role. By using a limited number of wave gauges, we accurately measure the NDR of the slowly varying envelope of the deep-water waves. …”

    “…We consider the low-energy effective field theory of heterotic string theory compactified on a seven-torus, and we construct electrically charged as well as more general solitonic solutions. These solutions preserve 1/2, 1/4, 1/8 and 1/16 of N=8, D=3 supersymmetry and have Killing spinors which exist due to cancellation of holonomies. …”

    Publicado 1996
    “…$P$-brane solutions of low-energy string actions have traditionally provided the first evidence for the existence of string dualities, in which fundamental and solitonic $p$-branes are identified with perturbative and non-perturbative BPS states. …”

    Publicado 1996
    “…This talk reviews some of the hot topics in spin physics and related subjects, including perturbative QCD predictions for polarized parton distributions and their possible behaviours at small x, the Bjorken and singlet sum rules and the treatment of higher orders in perturbative QCD, different interpretations of the EMC spin effect including chiral solitons and the axial U(1) anomaly, other experimental indications for the presence of strange quarks in the nucleon wave function, implications for dark matter physics, and a few words about polarization as a tool in electroweak physics.…”

    “…The spectrum of anomalous dimensions of very large operators has been calculated solving the Bethe ansatz equations in the thermodynamic limit, and matched to energies of string solitons. We have considered finite size corrections to the Bethe equations, that should correspond to quantum effects on the string side.…”

    “…Under the six-dimensional heterotic/type IIA duality map, a solitonic membrane solution of heterotic string theory transforms into a singular solution of type IIA theory, and should therefore be interpreted as a fundamental membrane in the latter theory. …”
