  • Resummation in QCD Fractional Analytic Perturbation Theory 
    Bakulev, A.P. (2010)
    We describe the generalization of Analytic Perturbation Theory (APT) for QCD observables, initiated by Radyushkin, Krasnikov, Pivovarov, Shirkov, and Solovtsov, to fractional powers of coupling — Fractional APT (FAPT). The ...

  • Retroreflecting Curves in Nonstandard Analysis 
    Almeida, R.; Neves, V.; Plakhov, A. (Журнал математической физики, анализа, геометрии, 2009)
    We present a direct construction of retroreflecting curves by means of Nonstandard Analysis. We construct non self-intersecting curves which are of class C¹, except for a hyper-finite set of values, such that the probability ...
  • Retrospective view on the last half century 
    Henderson, D. (Condensed Matter Physics, 2014)
    The year 2014 is a significant anniversary. Personally, it is 80 years since I was born. More importantly, it is one hundred years since the outbreak of the World War I, a catastrophe from which most of the world's present ...
  • Revealing novel quantum phases in quantum antiferromagnets on random lattices 
    Yu, R.; Haas, S.; Roscilde, T. (Condensed Matter Physics, 2009)
    Quantum magnets represent an ideal playground for the controlled realization of novel quantum phases and of quantum phase transitions. The Hamiltonian of the system can be indeed manipulated by applying a magnetic field ...
  • Revealing the hopping mechanism of conduction in heavily doped silicon diodes 
    Borblik, V. L.; Shwarts, Yu. M.; Shwarts, M. M. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)
    Measurements of temperature dependences of excess tunnel current in heavily doped silicon p-n junction diodes at fixed values of the forward bias are carried out in liquid helium temperature region. In some voltage interval, ...
