  • ANEC on stress-tensor states in perturbative λ ϕ 4 theory 
    Bautista, Teresa; Casarin, Lorenzo (Berlin ; Heidelberg : Springer ; [Trieste] : SISSA, 2023)
    We evaluate the Average Null Energy Condition (ANEC) on momentum eigenstates generated by the stress tensor in perturbative λ ϕ4 and general spacetime dimension. We first compute the norm of the stress-tensor state at ...
  • Coulomb branches for rank 2 gauge groups in 3d N= 4 gauge theories 
    Hanany, Amihay; Sperling, Marcus (Heidelberg : Springer Verlag, 2016)
    The Coulomb branch of 3-dimensional N=4 gauge theories is the space of bare and dressed BPS monopole operators. We utilise the conformal dimension to define a fan which, upon intersection with the weight lattice of a ...
  • Is the Nicolai map unique? 
    Lechtenfeld, Olaf; Rupprecht, Maximilian (Berlin, Heidelberg : Springer, 2022)
    The Nicolai map is a field transformation that relates supersymmetric theories at finite couplings g with the free theory at g = 0. It is obtained via an ordered exponential of the coupling flow operator integrated from 0 ...
  • 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 ...
  • 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 ...
  • Quantum SU(2|1) supersymmetric Calogero-Moser spinning systems 
    Fedoruk, Sergey; Ivanov, Evgeny; Lechtenfeld, Olaf; Sidorov, Stepan (Heidelberg : Springer Verlag, 2018)
    SU(2|1) supersymmetric multi-particle quantum mechanics with additional semi-dynamical spin degrees of freedom is considered. In particular, we provide an N= 4 supersymmetrization of the quantum U(2) spin Calogero-Moser ...
  • SU(2|1) supersymmetric mechanics on curved spaces 
    Kozyrev, Nikolay; Krivonos, Sergey; Lechtenfeld, Olaf; Sutulin, Anton (Heidelberg : Springer Verlag, 2018)
    We present SU(2|1) supersymmetric mechanics on n-dimensional Riemannian manifolds within the Hamiltonian approach. The structure functions including prepotentials entering the supercharges and the Hamiltonian obey extended ...
  • 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 ...
