- Abstract
- We investigate the one-dimensional polaron problem and calculate the ground-state energy and the effective mass. We use a real-time renormalization-group method and compare our results with first- and second-order perturbation theory, with Feynman's variational principle, and with the method of Lee, Low, and Pines.
