Non-Perturbative Renormalization Group Analysis of the Ohmic Quantum Dissipation
نویسندگان
چکیده
We analyze quantum tunneling with the Ohmic dissipation by the non-perturbative renormalization group method. We calculate the localization susceptibility to evaluate the critical dissipation for the quantum-classical transition, and find considerably larger critical dissipation compared to the previous semi-classical arguments.

Non-Perturbative Renormalization Group Approach for Quantum Dissipative Systems
We analyze the dissipative quantum tunneling in the Caldeira-Leggett model by the non-perturbative renormalization group method. We classify the dissipation effects by introducing the notion of effective cutoffs. We calculate the localization susceptibility to evaluate the critical dissipation for the quantum-classical transition. Our results are consistent with previous semi-classical argument...
متن کاملSmeared quantum phase transition in the dissipative random quantum Ising model
We investigate the quantum phase transition in the random transverse-field Ising model under the influence of Ohmic dissipation. To this end, we numerically implement a strong-disorder renormalization-group scheme. We find that Ohmic dissipation destroys the quantum critical point and the associated quantum Griffiths phase by smearing. Our results quantitatively confirm a recent theory [Phys. R...
متن کاملKondo physics and dissipation: A numerical renormalization-group approach to Bose-Fermi Kondo models
We extend the numerical renormalization-group method to treat Bose-Fermi Kondo models BFKMs describing a local moment coupled both to a conduction band and to a dissipative bosonic bath representing, e.g., lattice or spin collective excitations of the environment. We apply the method to the Ising-symmetry BFKM with a structureless band and a bath spectral function s. The method is valid for all...
متن کاملNumerical renormalization group for bosonic systems and application to the sub-ohmic spin-boson model.
We describe the generalization of Wilson's numerical renormalization group method to quantum impurity models with a bosonic bath, providing a general nonperturbative approach to bosonic impurity models which can access exponentially small energies and temperatures. As an application, we consider the spin-boson model, describing a two-level system coupled to a bosonic bath with power-law spectra...
متن کاملInfluence of super-ohmic dissipation on a disordered quantum critical point.
We investigate the combined influence of quenched randomness and dissipation on a quantum critical point with O(N) order-parameter symmetry. Utilizing a strong-disorder renormalization group, we determine the critical behavior in one space dimension exactly. For super-ohmic dissipation, we find a Kosterlitz-Thouless type transition with conventional (power-law) dynamical scaling. The dynamical ...
