On the finite volume expectation values of local operators in the sine-Gordon model
In this paper we present sets of linear integral equations which make possible to compute the finite volume expectation values of the trace of the stress energy tensor (Θ) and the U(1) current (Jμ) in any eigenstate of the Hamiltonian of the sine-Gordon model. The solution of these equations in the...
