Effective potentials and kink spectra in non-integrable perturbed conformal field theories
G. Mussardo, G. Takacs
We analyze the evolution of the effective potential and the particle spectrum of two-parameter families of non-integrable quantum field theories. These theories are defined by defo…
Form factors of boundary exponential operators in the sinh-Gordon model
G. Takacs
Using the recently introduced boundary form factor bootstrap equations, the form factors of boundary exponential operators in the sinh-Gordon model are constructed. The ultraviolet…
Boundary form factors in finite volume
M. Kormos, G. Takacs
We describe the volume dependence of matrix elements of local boundary fields to all orders in inverse powers of the volume. Using the scaling boundary Lee-Yang model as testing gr…
Spectrum of local boundary operators from boundary form factor bootstrap
M. Szots, G. Takacs
Using the recently introduced boundary form factor bootstrap equations, we map the complete space of their solutions for the boundary version of the scaling Lee-Yang model and sinh…
On the boundary form factor program
Z. Bajnok, L. Palla, G. Takacs
Boundary form factor axioms are derived for the matrix elements of local boundary operators in integrable 1+1 dimensional boundary quantum field theories using the analyticity prop…
Casimir force between planes as a boundary finite size effect
Z. Bajnok, L. Palla, G. Takacs
The ground state energy of a boundary quantum field theory is derived in planar geometry in D+1 dimensional spacetime. It provides a universal expression for the Casimir energy whi…
