Query: Removing Tadpoles in a Soliton Sector   It has long been known that perturbative calculations can be performed in a
soliton sector of a quantum field theory by using a soliton Hamiltonian, which
is constructed from the defining Hamiltonian by shifting the field by the
classical soliton solution. It is also known that even if tadpoles are
eliminated in the vacuum sector, they remain in the soliton sector. In this
note we show, in the case of quantum kinks at two loops, that the soliton
sector tadpoles may be removed by adding certain quantum corrections to the
classical solution used in this construction. Stated differently, the
renormalization condition that the soliton sector tadpoles vanish may be
satisfied by renormalizing the soliton solution.
