Ballistic magneto-thermal transport in a Heisenberg spin chain at low temperatures
Lifa Zhang, Jian-Sheng Wang, Baowen Li
We study ballistic thermal transport in Heisenberg spin chain with nearest-neighbor ferromagnetic interactions at low temperatures. Explicit expressions for transmission coefficien…
Heat conduction in a 1D harmonic chain with three dimensional vibrations
Zonghua Liu, Baowen Li
We study vibrational energy transport in a quasi 1-D harmonic chain with both longitudinal and transverse vibrations. We demonstrate via both numerical simulation and theoretic ana…
Thermal rectifier from deformed carbon nanohorns
Gang Wu, Baowen Li
We study thermal rectification in single-walled carbon nanohorns (SWNHs) by using non-equilibrium molecular dynamics (MD) method. It is found that the horns with the bigger top ang…
Heat conduction in simple networks: The effect of inter-chain coupling
Zonghua Liu, Baowen Li
The heat conduction in simple networks consisting of different one dimensional nonlinear chains is studied. We find that the coupling between chains has different function in heat…
Thermal Logic Gates: Computation with phonons
Lei Wang, Baowen Li
Logic gates are basic digital elements for computers. We build up thermal logic gates that can perform similar operations as their electronic counterparts. The thermal logic gates…
