The ground state of a two-level system coupled to a dispersionless phonon bath is studied. The exact ground-state solution to the problem is obtained via a combination of unitary transformations and numerical diagonalization. The impossibility of the discontinuous localization-delocalization transit

An expression of the ground state energy E SB of the spin-boson Hamiltonian H SB is considered. The expression in the cases of both massive and massless bosons is given by a nonperturbative method. By using the expression, we show a necessary and sufficient condition with respect to a parameter G #

A generalization of the standard spin-boson model is considered. The Hamiltonian H(:) of the model with a coupling parameter : # R acts in the tensor product H F b of a Hilbert space H and the boson (symmetric) Fock space F b over L 2 (R & ). The existence and uniqueness of ground states of H(:) are
