A general product of tensors with applications
Jia-Yu Shao
We define a general product of two -dimensional tensors and with orders and , respectively. This product is a generalization of the…
Thermal conductivities of one-dimensional anharmonic/nonlinear lattices: renormalized phonons and effective phonon theory
Nianbei Li, Baowen Li
Heat transport in low-dimensional systems has attracted enormous attention from both theoretical and experimental aspects due to its significance to the perception of fundamental e…
Classical Heat Transport in Anharmonic Molecular Junctions: Exact Solutions
Sha Liu, Bjiay Kumar Agarwalla, Jian-Sheng Wang +1
We study full counting statistics for classical heat transport through anharmonic/nonlinear molecular junctions formed by interacting oscillators. Analytical result of the steady s…
Topological Magnon Insulator in Insulating Ferromagnet
Lifa Zhang, Jie Ren, Jian-Sheng Wang +1
In the ferromagnetic insulator with Dzyaloshinskii-Moriya interaction, we theoretically predict and numerically verify a topological magnon insulator, where the charge-free magnon…
Anomalous Heat Conduction and Anomalous Diffusion in Low Dimensional Nanoscale Systems
Sha Liu, Xiangfan Xu, Rongguo Xie +2
Thermal transport is an important energy transfer process in nature. Phonon is the major energy carrier for heat in semiconductor and dielectric materials. In analogy to Ohm's law…
High-order Green Operators on the Disk and the Polydisc
Yang Liu, Zhihua Chen, Yifei Pan
In this paper, we give the explicit expressions of high-order Green operators on the disk and the polydisc, and hence the kernel functions of high-order Green operators are also pr…
