  • Asymptotic symmetries of scalar electrodynamics and of the abelian Higgs model in Hamiltonian formulation 
    Tanzi, Roberto; Giulini, Domenico (Berlin ; Heidelberg : Springer, 2021)
    We investigate the asymptotic symmetry group of a scalar field minimally-coupled to an abelian gauge field using the Hamiltonian formulation. This extends previous work by Henneaux and Troessaert on the pure electromagnetic ...
  • Asymptotic symmetries of Yang-Mills fields in Hamiltonian formulation 
    Tanzi, Roberto; Giulini, Domenico (Berlin ; Heidelberg : Springer, 2020)
    We investigate the asymptotic symmetry group of the free SU(N )-Yang-Mills theory using the Hamiltonian formalism. We closely follow the strategy of Henneaux and Troessaert who successfully applied the Hamiltonian formalism ...
  • Auxiliary tensor fields for Sp(2, R) self-duality 
    Ivanov, Evgeny A.; Lechtenfeld, Olaf; Zupnik, Boris M. (New York : Springer, 2015)
    The coset Sp(2, R)/U(1) is parametrized by two real scalar fields. We generalize the formalism of auxiliary tensor (bispinor) fields in U(1) self-dual nonlinear models of abelian gauge fields to the case of Sp(2, R) ...
  • The coupling flow of N = 4 super Yang-Mills theory 
    Rupprecht, Maximilian (Berlin, Heidelberg : Springer, 2022)
    We offer a novel perspective on N = 4 supersymmetric Yang-Mills (SYM) theory through the framework of the Nicolai map, a transformation of the bosonic fields that allows one to compute quantum correlators in terms of a ...
  • Erratum: Revisiting coupling selection rules in heterotic orbifold models (Journal of High Energy Physics (2012) 05 (008)) 
    Kobayashi, Tatsuo; Parameswaran, Susha L.; Ramos-Sánchez, Saul; Zavala, Ivonne (Heidelberg : Springer Verlag, 2012)
    Erratum to: Revisiting coupling selection rules in heterotic orbifold models in: Journal of High Energy Physics (2012) 05:8
  • 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 ...
  • Revisiting coupling selection rules in heterotic orbifold models 
    Kobayashi, Tatsuo; Parameswaran, Susha L.; Ramos-Sánchez, Saul; Zavala, Ivonne (Heidelberg : Springer Verlag, 2012)
    We study L-point couplings between twisted sector fields in heterotic orbifold compactifications, using conformal field theory. Selection rules provide an easy way to identify which couplings are non-vanishing. Those used ...
