چکیده
A scattering description is proposed for a boundary perturbation of a c = 1 SL(2, Z) invariant conformal field theory. The bulk massless S-matrices are of the form of Zamolodchikov’s staircase model. Using the boundary version of the thermodynamic Bethe ansatz, we show that the boundary free energy goes through a series of integer valued plateaux as a function of system size. Typeset using REVTEX

A subjective and incomplete list of interesting and unique features of the deconfinement phase transition is presented. Furthermore a formal similarity of the density matrix of the Aharonov-Bohm system and QCD is mentioned, as well.

We discuss questions arising from the recent work of Schellekens[17], and also from an earlier paper by Schellekens and Yankielowicz[19]. We summarise Schellekens' results, and proceed to discuss the uniqueness of the c = 24 self-dual conformal field theory with no weight one states, i.e. the Monster module V ♮ [8]. After introducing the concept of complementary representations, we examine Z 2-...

We compute by Bethe Ansatz both bulk and boundary hole scattering matrices for the critical A (1) N−1 quantum spin chain. The bulk S matrix coincides with the soliton S matrix for the A (1) N−1 Toda field theory with imaginary coupling. We verify our result for the boundary S matrix using a generalization of the Ghoshal-Zamolodchikov boundary crossing relation.

Supersymmetric σ-models obtained by constraining linear supersymmetric field theories are ill defined. Well defined subsectors parametrising Kahler manifolds exist but are not believed to arise directly from constrained linear ones. A counterexample is offered using improved understanding of membranes in superstring theories leading to crucial central terms modifying the algebra of supercharge ...

Classification of N = 4 superconformal symmetries in two dimensions is reexamined. It is proposed that apart from SU(2) and SU(2)×SU(2)×U(1) their Kac-Moody symmetry can also be SU(2) × (U(1)) 4. These supercon-formal symmetries and corresponding algebras are named small, large and middle ones respectively. Operator product expansions for the middle algebra are derived. Complete free field real...
