# Finite thermal conductivity in 1D models having zero Lyapunov exponents.

@article{Li2002FiniteTC, title={Finite thermal conductivity in 1D models having zero Lyapunov exponents.}, author={Baowen Li and Lei Wang and Bambi Hu}, journal={Physical review letters}, year={2002}, volume={88 22}, pages={ 223901 } }

Heat conduction in three types of 1D channels is studied. The channels consist of two parallel walls, right triangles as scattering obstacles, and noninteracting particles. The triangles are placed along the walls in three different ways: (i) periodic, (ii) disordered in height, and (iii) disordered in position. The Lyapunov exponents in all three models are zero because of the flatness of triangle sides. It is found numerically that the temperature gradient can be formed in all three channels…
