Temperature and Frequency Dependent Mean Free Paths of Renormalized Phonons in Nonlinear Lattices
Nianbei Li, Junjie Liu, Changqin Wu +1
In the regime of strong nonlinearity, the validity of conventional perturbation based phonon transport theories is questionable. In particular, the renormalized phonons instead of…
Variational approach to renormalized phonon in momentum-nonconserving nonlinear lattices
Junjie Liu, Baowen Li, Changqin Wu
A previously proposed variational approach for momentum-conserving systems [J. Liu et.al., Phys. Rev. E 91, 042910 (2015)] is extended to systematically investigate general momentu…
Decoherence and Energy Relaxation in the Quantum-Classical Dynamics for Charge Transport in Organic Semiconducting Crystals: an Instantaneous Decoherence Correction Approach
Wei Si, Chang-Qin Wu
We explore an instantaneous decoherence correction (IDC) approach for the decoherence and energy relaxation in the quantum-classical dynamics of charge transport in organic semicon…
Renormalized phonons in nonlinear lattices: A variational approach
Junjie Liu, Sha Liu, Nianbei Li +2
We propose a variational approach to study renormalized phonons in momentum conserving nonlinear lattices with either symmetric or asymmetric potentials. To investigate the influen…
