We use a non-perturbative renormalization-group technique to study interacting bosons at zero temperature. Our approach reveals the instability of the Bogoliubov fixed point when d ≤ 3 and yields the exact infrared behavior in all dimensions d > 1 within a rather simple theoretical framework. It also enables to compute the low-energy properties in terms of the parameters of a microscopic model....
متن کاملRenormalization Group Approach to Zero Temperature Bose Condensation
We study the problem of Bose condensation at zero temperature and weak coupling for a three dimensional system of bosons, interacting with a repulsive short range potential, in the Bogoliubov approximation. We prove that the properties of the model can be explained in terms of an anomalous asymptotically free renormalization group ow and we show that the two-point correlation function has the t...
متن کاملNon-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 کاملNon Perturbative Renormalization Group and Bose-Einstein Condensation
These lectures are centered around a specific problem, the effect of weak repulsive interactions on the transition temperature Tc of a Bose gas. This problem provides indeed a beautiful illustration of many of the techniques which have been discussed at this school on effective theories and renormalization group. Effective theories are used first in order to obtain a simple hamiltonian describi...
متن کاملA perturbative renormalization group approach to driven quantum systems.
We use a perturbative momentum shell renormalization group (RG) approach to study the properties of a driven quantum system at zero temperature. To illustrate the technique, we consider a bosonic ϕ(4) theory with an arbitrary time dependent interaction parameter λ(t) = λ f(ω0t), where ω0 is the drive frequency and we derive the RG equations for the system using a Keldysh diagrammatic technique....
