Exact Boundary Critical Exponents and Tunneling Effect in Integrable Models for Quantum Wires
Y. Wang, J. Voit, F. -C. Pu
Using the principles of the conformal quantum field theory and the finite size corrections of the energy of the ground and various excited states, we calculate the boundary critica…
