Exact Finite-Size Spectra in the Kondo Problem and Boundary Conformal Field Theory
S. Fujimoto, N. Kawakami, S. -K. Yang
The exact finite-size spectra for several quantum impurity models related to the Kondo problem are obtained from the Bethe ansatz solutions. Using the finite-size scaling in bounda…
