We provide new insight into the Kondo problem by constructing trial wave
functions and exactly solvable models. For the spin-1/2 case, we found a
Gutzwiller projected Fermi sea wave function, which can also be represented as
a Jastrow product originated from a conformal field theory correlator (quite
similar to the Moore-Read construction of fractional quantum Hall wave
functions). We also found a parent Hamiltonian with inverse-square hopping
terms and also inverse-square Kondo interactions. The machinery developed here
sheds light on how to construct trial wave functions and exactly solvable
models for more complicated Kondo problems.
