Their thermal counterparts, heat current limiters and constant heat current sources, are still not available yet. By combining two typical nonlinear lattices, the Frenkel-Kontorova (FK) lattice and a coupled rotator lattice, together, we present by numerical simulation a model that displays complete negative differential thermal resistance (NDTR). Namely, in a wide regime, the heat current that flows through this model is always a decreasing function of the temperature drop applied to it, no matter whether the change in the temperature drop is due to a change in the high or the low temperature. We show that, upon being properly set up, a complete NDTR can work as either a heat current limiter or a constant heat current source. © 2012 American Physical Society.||Source Title:||Physical Review E - Statistical, Nonlinear, and Soft Matter Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/96770||ISSN:||15393755||DOI:||10.1103/PhysRevE.85.061112|
