  • Dynamics for holographic codes 
    Osborne, Tobias J.; Stiegemann, Deniz E. (Berlin ; Heidelberg : Springer, 2020)
    We describe how to introduce dynamics for the holographic states and codes introduced by Pastawski, Yoshida, Harlow and Preskill. This task requires the definition of a continuous limit of the kinematical Hilbert space ...
  • 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 ...
  • Liouville description of conical defects in dS4, Gibbons-Hawking entropy as modular entropy, and dS3 holography 
    Arias, Cesar; Diaz, Felipe; Olea, Rodrigo; Sundell, Per (Berlin ; Heidelberg : Springer, 2020)
    We model the back-reaction of a static observer in four-dimensional de Sitter spacetime by means of a singular ℤq quotient. The set of fixed points of the ℤq action consists of a pair of codimension two minimal surfaces ...
  • Minimal realization of ℓ-conformal Galilei algebra, Pais-Uhlenbeck oscillators and their deformation 
    Krivonos, Sergey; Lechtenfeld, Olaf; Sorin, Alexander (Heidelberg : Springer Verlag, 2016)
    We present the minimal realization of the ℓ-conformal Galilei group in 2+1 dimensions on a single complex field. The simplest Lagrangians yield the complex PaisUhlenbeck oscillator equations. We introduce a minimal deformation ...
  • PT deformation of angular Calogero models 
    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 ...
  • Spinning extensions of D (2 ; 1; α) superconformal mechanics 
    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 ...
  • SU(2|2) supersymmetric mechanics 
    Ivanov, Evgeny; Lechtenfeld, Olaf; Sidorov, Stepan (Heidelberg : Springer Verlag, 2016)
    We introduce a new kind of non-relativistic N = 8 supersymmetric mechanics, associated with worldline realizations of the supergroup SU(2|2) treated as a deformation of flat N = 8, d=1 supersymmetry. Various worldline ...
  • Superconformal SU(1, 1|n) mechanics 
    Galajinsky, Anton; Lechtenfeld, Olaf (Heidelberg : Springer Verlag, 2016)
    Recent years have seen an upsurge of interest in dynamical realizations of the superconformal group SU(1, 1|2) in mechanics. Remarking that SU(1, 1|2) is a particular member of a chain of supergroups SU(1, 1|n) parametrized ...
