Query: Mapping of the Anisotropic Two-channel Anderson Model onto a
  Fermi-Majorana bi-Resonant Level Model   We establish the correspondence between an extended version of the
two-channel Anderson model and a particular type of bi-resonant level model.
For certain values of the parameters the new model becomes quadratic. We
calculate in closed form the entropy and impurity occupation as functions of
temperature and identify the different physical energy scales of the problem.
We show how, as the temperature goes to zero, the model approaches a universal
line of fixed points non-Fermi liquid in nature.
