Symmetry and the critical phase of the two-bath spin-boson model : ground-state properties

A generalized trial wave function termed as the "multi-D1 ansatz'' has been developed to study the ground state of the spin-boson model with simultaneous diagonal and off-diagonal coupling in the sub-Ohmic regime. Ground state properties including the energy and the spin polarization...
