Toda field theories and Calogero models associated to infinite Weyl groups
Andreas Fring
Many integrable theories can be formulated universally in terms of Lie algebraic root systems. Well-studied are conformally invariant scalar field theories of Toda type and their m…
Higher time-derivative theories from space-time interchanged integrable field theories
Andreas Fring, Takano Taira, Bethan Turner
We compare a relativistic and a nonrelativistic version of Ostrogradsky's method for higher-time derivative theories extended to scalar field theories and consider as an alternativ…
Integrable scattering theory with higher derivative Hamiltonians
Andreas Fring, Bethan Turner
We discuss how a standard scattering theory a of multi-particle theory generalises to systems based on Hamiltonians that involve higher-order derivatives in their quantum mechanica…
Higher derivative Hamiltonians with benign ghosts from affine Toda lattices
Andreas Fring, Bethan Turner
We provide further evidence for Smilga's conjecture that higher charges of integrable systems are suitable candidates for higher derivative theories that possess benign ghost secto…
Moduli spaces for PT-regularized solitons
Francisco Correa, Andreas Fring, Takanobu Taira
We construct and analyse the moduli space (collective coordinates) for a classical field theory in 1 + 1 dimensions that possesses complex stable multi-soliton solutions with real…
Non-Hermitian gauge field theories and BPS limits
Andreas Fring, Takanobu Taira
We present an overview of some key results obtained in a recent series devoted to non-Hermitian quantum field theories for which we systematically modify the underlying symmetries.…
