Renormalons in integrable field theories [PDF]

Journal of High Energy Physics, 2020
In integrable field theories in two dimensions, the Bethe ansatz can be used to compute exactly the ground state energy in the presence of an external field coupled to a conserved charge.

Integrable Field Theories with Defects [PDF]

Czechoslovak Journal of Physics, 2006
The structure of integrable field theories in the presence of defects is discussed in terms of boundary functions under the Lagrangian formalism. Explicit examples of bosonic and fermionic theories are considered.

Noncommutative Integrable Field Theories in 2d [PDF]

Nuclear Physics B, 2002
We study the noncommutative generalization of (euclidean) integrable models in two-dimensions, specifically the sine- and sinh-Gordon and the U(N) principal chiral models. By looking at tree-level amplitudes for the sinh-Gordon model we show that its na\"

Quantum Quenches in Integrable Field Theories [PDF]

New Journal of Physics, 2010
We study the non equilibrium time evolution of an integrable field theory in 1+1 dimensions after a sudden variation of a global parameter of the Hamiltonian.

Scaling limits of integrable quantum field theories [PDF]

Reviews in Mathematical Physics, 2011
Short distance scaling limits of a class of integrable models on two-dimensional Minkowski space are considered in the algebraic framework of quantum field theory.

Integrable Quantum Field Theories with Unstable Particles [PDF]

Physics Letters B, 1999
A new family of S-matrix theories with resonance poles is constructed and conjectured to correspond to the Homogeneous sine-Gordon theories associated with simply laced compact Lie groups, where some of the resonance poles can be traced to the presence ...

The ultraviolet Behaviour of Integrable Quantum Field Theories, Affine Toda Field Theory [PDF]

Nuclear Physics B, 1999
We investigate the thermodynamic Bethe ansatz (TBA) equations for a system of particles which dynamically interacts via the scattering matrix of affine Toda field theory and whose statistical interaction is of a general Haldane type.

Discreteness and integrality in Conformal Field Theory [PDF]

Journal of High Energy Physics, 2021
Abstract Various observables in compact CFTs are required to obey positivity, discreteness, and integrality. Positivity forms the crux of the conformal bootstrap, but understanding of the abstract implications of discreteness and integrality for the space of CFTs is lacking.
