AB  - For a broad class of quantum models of practical interest, we demonstrate that 
      the Hamiltonian of the system nonlinearly coupled to a harmonic bath through the 
      system and bath coordinates can be equivalently mapped into the Hamiltonian of 
      the system bilinearly coupled to the bath through the system and bath momenta. We 
      show that the Hamiltonian with bilinear system-bath momentum coupling can be 
      treated by the hierarchical equations-of-motion (HEOM) method and present the 
      corresponding proof-of-principle simulations. The developed methodology creates 
      the opportunity to scrutinize a new family of nonlinear quantum systems by the 
      numerically accurate HEOM method.
