Title: | Quantum entanglement and the self-trapping transition in polaronic systems | Authors: | Zhao, Yang Zanardi, Paolo Chen, Guan Hua |

Quantum Entanglement and the Self-Trapping Transition in Polaronic Systems. Physical review B, 70, 1-5. | Series/Report no.: | Physical review B | Abstract: | We revisit from a quantum-information perspective a classic problem of polaron theory in one dimension. In the context of the Holstein model we show that a simple analysis of quantum entanglement between excitonic and phononic degrees of freedom allows one to effectively characterize both the small and large polaron regimes as well as the crossover in between. The small (large) polaron regime corresponds to a high (low) degree of bipartite quantum entanglement between the exciton and the phonon cloud that clothes the exciton. Moreover, the self-trapping transition is clearly displayed by a sharp drop of exciton-phonon entanglement. | URI: | https://hdl.handle.net/10356/90390 http://hdl.handle.net/10220/6729 |
