Thermal memory: a storage of phononic information
Lei Wang, Baowen Li
Memory is an indispensable element for computer besides logic gates. In this Letter we report a model of thermal memory. We demonstrate via numerical simulation that thermal (phono…
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…
Thermal transistor: Heat flux switching and modulating
Wei Chung Lo, Lei Wang, Baowen Li
Thermal transistor is an efficient heat control device which can act as a heat switch as well as a heat modulator. In this paper, we study systematically one-dimensional and two-di…
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…
The ratchet effect and the transporting islands in the chaotic sea
Lei Wang, Giuliano Benenti, Giulio Casati +1
We study directed transport in a classical deterministic dissipative system. We consider the generic case of mixed phase space and show that large ratchet currents can be generated…
