Exact finite volume expectation values of conserved currents

Exact finite volume expectation values of conserved currents

The vacuum expectation values of conserved currents play an essential role in the generalized hydrodynamics of integrable quantum field theories. We use analytic continuation to extend these results for the excited state expectation values in a finite volume. Our formulas are valid for diagonally sc...
