The quantum double in integrable quantum field theory [PDF]
Nuclear Physics B, 1993 Various aspects of recent works on affine quantum group symmetry of integrable 2d quantum field theory are reviewed and further clarified. A geometrical meaning is given to the quantum double, and other properties of quantum groups. Multiplicative presentations of the Yangian double are analyzed.

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.

Lax Connections in $T\bar{T}$-deformed Integrable Field Theories [PDF]
, 2021 In this work, we try to construct the Lax connections of T T̄ -deformed integrable field theories in two different ways. With reasonable assumptions, we make ansatz and find the Lax pairs in the T T̄ -deformed affine Toda theories and the principal ...

Symmetry resolved entanglement in integrable field theories via form factor bootstrap [PDF]
Journal of High Energy Physics, 2020 We consider the form factor bootstrap approach of integrable field theories to derive matrix elements of composite branch-point twist fields associated with symmetry resolved entanglement entropies.

Null-Vectors in Integrable Field Theory [PDF]
Communications in Mathematical Physics, 1997 The form factor bootstrap approach allows to construct the space of local fields in the massive restricted sine-Gordon model. This space has to be isomorphic to that of the corresponding minimal model of conformal field theory. We describe the subspaces which correspond to the Verma modules of primary fields in terms of the commutative algebra of local

Integrable field theories with an interacting massless sector [PDF]
, 2020 We present the first known integrable relativistic field theories with interacting massive and massless sectors. And we demonstrate that knowledge of the massless sector is essential for understanding of the spectrum of the massive sector.

TOPOLOGICAL FIELD THEORIES AND THE PERIOD INTEGRALS [PDF]
Modern Physics Letters A, 1993 We discuss topological Landau-Ginzburg theories coupled to two-dimensional topological gravity. We point out that the basic recursion relations for correlation functions of the two-dimensional gravity have exactly the same form as the Gauss-Manin differential equations for the period integrals of superpotentials.

T T ¯ $$ T\overline{T} $$ -deformation and long range spin chains
Journal of High Energy Physics, 2020 We point out that two classes of deformations of integrable models, developed completely independently, have deep connections and share the same algebraic origin. One class includes the T T ¯ $$ T\overline{T} $$ -deformation of 1+1 dimensional integrable
