  • Integrability, intertwiners and non-linear algebras in Calogero models 
    Carrillo-Morales, Francisca; Correa, Francisco; Lechtenfeld, Olaf (Berlin ; Heidelberg : Springer, 2021)
    For the rational quantum Calogero systems of type A1⊕A2, AD3 and BC3, we explicitly present complete sets of independent conserved charges and their nonlinear algebras. Using intertwining (or shift) operators, we include ...
  • New N = 2 superspace Calogero models 
    Krivonos, Sergey; Lechtenfeld, Olaf; Sutulin, Anton (Berlin ; Heidelberg : Springer, 2020)
    Starting from the Hamiltonian formulation of N = 2 supersymmetric Calogero models associated with the classical An, Bn, Cn and Dn series and their hyperbolic/trigonometric cousins, we provide their superspace description. ...
  • PT deformation of Calogero-Sutherland models 
    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 ...
  • Regularized degenerate multi-solitons 
    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 ...
  • The tetrahexahedric angular Calogero model 
    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 ...
  • Transmission amplitudes from Bethe ansatz equations 
    Doikou, Anastasia; Karaiskos, Nikos (New York, NY : Springer International Publishing, 2013)
    We consider the Heisenberg spin chain in the presence of integrable spin defects. Using the Bethe ansatz methodology, we extract the associated transmission amplitudes, that describe the interaction between the particle-like ...
