Diagonal multi-soliton matrix elements in finite volume
T. Pálmai, G. Takács
We consider diagonal matrix elements of local operators between multi-soliton states in finite volume in the sine-Gordon model, and formulate a conjecture regarding their finite si…
Sine-Gordon form factors in finite volume
G. Feher, G. Takacs
We compare form factors in sine-Gordon theory, obtained via the bootstrap, to finite volume matrix elements computed using the truncated conformal space approach. For breather form…
Form factor perturbation theory from finite volume
G. Takacs
Using a regularization by putting the system in finite volume, we develop a novel approach to form factor perturbation theory for nonintegrable models described as perturbations of…
Finite temperature expectation values of boundary operators
G. Takacs
A conjecture is presented for the thermal one-point function of boundary operators in integrable boundary quantum field theories in terms of form factors. It is expected to have ap…
Casimir effect in the boundary state formalism
Z. Bajnok, L. Palla, G. Takacs
Casimir effect in the planar setting is described using the boundary state formalism, for general partially reflecting boundaries. It is expressed in terms of the low-energy degree…
Form factors in finite volume I: form factor bootstrap and truncated conformal space
B. Pozsgay, G. Takacs
We describe the volume dependence of matrix elements of local fields to all orders in inverse powers of the volume (i.e. only neglecting contributions that decay exponentially with…
