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…

1D momentum-conserving systems: the conundrum of anomalous versus normal heat transport
Yunyun Li, Sha Liu, Nianbei Li +2
Transport and diffusion of heat in one dimensional (1D) nonlinear systems which {\it conserve momentum} is typically thought to proceed anomalously. Notable exceptions, however, ex…
