    In a previous work [1], we proposed an integrability setup for computing nonplanar corrections to correlation functions in N=4 super-Yang-Mills theory at any value of the coupling constant. The procedure consists of drawing ...
  • Correa, Francisco; Lechtenfeld, Olaf (Heidelberg : Springer Verlag, 2017)
    The rational Calogero model based on an arbitrary rank-n Coxeter root system is spherically reduced to a superintegrable angular model of a particle moving on S n−1 subject to a very particular potential singular at the ...
  • Correa, F.; Lechtenfeld, O. (Heidelberg : Springer Verlag, 2019)
    Calogero-Sutherland models of N identical particles on a circle are deformed away from hermiticity but retaining a PT symmetry. The interaction potential gets completely regularized, which adds to the energy spectrum an ...
  • Feigin, Mikhail; Lechtenfeld, Olaf; Polychronakos, Alexios P. (New York, NY : Springer International Publishing, 2013)
    The rational Calogero-Moser model of n one-dimensional quantum particles with inverse-square pairwise interactions (in a confining harmonic potential) is reduced along the radial coordinate of R-n to the 'angular Calogero-Moser ...
  • Correa, Francisco; Fring, Andreas (Heidelberg : Springer Verlag, 2016)
    We report complex PT-symmetric multi-soliton solutions to the Korteweg de-Vries equation that asymptotically contain one-soliton solutions, with each of them possessing the same amount of finite real energy. We demonstrate ...
  • Galajinsky, Anton; Lechtenfeld, Olaf (Berlin : Springer, 2019)
    As is known, any realization of SU(2) in the phase space of a dynamical sys- tem can be generalized to accommodate the exceptional supergroup D (2 ; 1;α ), which is the most general N = 4 supersymmetric ...
  • Correa, Francisco; Lechtenfeld, Olaf (New York : Springer, 2015)
    The spherical reduction of the rational Calogero model (of type A n−1 and after removing the center of mass) is considered as a maximally superintegrable quantum system, which describes a particle on the (n−2)-sphere subject ...
