  Based on the recently developed light-front similarity renormalization group
approach and the light-front heavy quark effective theory, we derive
analytically from first-principles QCD a heavy quark light-front Hamiltonian
which contains explicitly a confinement interaction at long distances and a
Coulomb-type interaction at short distances. With this light-front QCD
Hamiltonian, we further demonstrate that the nonperturbative QCD dynamics of
the strongly interacting heavy hadron bound states can be treated as a
weak-coupling problem.
