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 ...
Ground-state properties of sub-Ohmic spin-boson model with simultaneous diagonal and off-diagonal coupling
By employing a variational approach, the density matrix renormalization group (DMRG), the exact diagonalization, and symmetry and mean-field analyses, the ground-state properties of the two-bath spin-boson model with ...
Optimal Energy Transfer in Light-Harvesting Systems
Photosynthesis is one of the most essential biological processes in which specialized pigment-protein complexes absorb solar photons, and with a remarkably high efficiency, guide the photo-induced excitation energy toward ...
