Can I read Expectation values of boundary fields in the boundary sine-Gordon model on EtoBox?

Expectation values of boundary fields in the boundary sine-Gordon model by Fateev, V.; Lukyanov, S.; Zamolodchikov, A.; Zamolodchikov, Al. is a scholarly article available to read on EtoBox.

What is Expectation values of boundary fields in the boundary sine-Gordon model about?

We propose an explicit expression for vacuum expectation values of the boundary field e^{ia\phi_{B}} in the boundary sine-Gordon model with zero bulk mass. This expression agrees with known exact results for the boundary free energy and with perturbative calculations.
