Boundary Bound States in Affine Toda Field Theory
... Our presentation is organised as follows. In section 2 we briefly review some of the main features of the S-and W-matrices. Section 3 is devoted to a general discus- sion of the boundary bound state bootstrap equation, ...

The ultraviolet behaviour of integrable quantum field theories, affine Toda field theory
... 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 ...

Braid Relations in Affine Toda Field Theory
... For this equation to hold it is crucial that all masses renormalise uniformly, i.e. the classical mass ratios pertain. This is a somewhat unappealing feature which still plagues the bootstrap approach, that one still has ...

Form factors of boundary fields for the A(2)-affine Toda field theory
... the boundary has been proposed recently [15]. It turns out that if one considers the bound- ary as a point-like object sitting at the origin of space (x = 0), then a natural generalisation of the bulk form factor program ...

Vertex operators and soliton time delays in affine Toda field theory
... Affine Toda field theories [1] are relativistically invariant field theories which are integrable in a space-time of two dimensions and possess a natural interpretation as special deformations of ...

Affine Toda Field Theory in the Presence of Reflecting Boundaries
... Several problems in quantum mechanics, like dissipative systems[2] can be un- derstood as a quantum field theory in the presence of boundaries [3]. In particular, one might get some more insight into the ...

Universal boundary reflection amplitudes
... The non-uniqueness of the solution is related to the fact that one can make use of the transformations (2.8)-(2.11) and always produce new types of solutions. The natural question which arises is: Which of these ...

Rational sequences for the conductance in quantum wires from affine Toda field theories

Why Interpret Quantum Physics?
... The atomic physics community experienced a deep crisis in the period from 1922 to 1927. The Bohr-Som- merfeld atomic theory was recognized as inadequate. Wave-particle duality became problematic for electrons as ...

Hamiltonian approaches of field theory
... The multitime Hamilton equations were first written in a book by de Donder [2]. But, to the authors’ knowledge, there is no prior work aimed at developing a theory of multitime Hamilton equations with periodic ...

Rational reductions of the 2D-Toda hierarchy and mirror symmetry
... The paper is organized as follows. In Section 2, after reviewing the Lax formalism for the 2D-Toda hierarchy, we first construct the RR2T in the bi-infinite case, study the reduction of the 2D-Toda flows, ...

The Philosophy of Quantum Field Theory
... It seems too good to be true, and indeed, Wallace and Timpson (2007) argue that Deutsch and Hayden’s formalism misrepresents their interpretation. Wallace and Timpson identify a class of space-and-time-dependent phase ...

Resonances and lattice field theory
