|Title:||Emergence and control of heat current from strict zero thermal bias||Authors:||Ren, J.
|Issue Date:||4-Feb-2010||Citation:||Ren, J., Li, B. (2010-02-04). Emergence and control of heat current from strict zero thermal bias. Physical Review E - Statistical, Nonlinear, and Soft Matter Physics 81 (2) : -. ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevE.81.021111||Abstract:||It is an ever-growing challenge to develop nanodevices for controlling energy transport. An open question is whether we can create and control heat current at strict zero thermal bias, and if yes, how to do it. In this paper, we demonstrate that a nonlinear asymmetric system, when pushed out of equilibrium, can produce heat current in the absence of a thermal bias. The emergence and control of heat current over a broad range of parameters are studied. Our results reveal the following three necessary conditions: nonequilibrium source, symmetry breaking, and nonlinearity. We also demonstrate that when heat baths are correlated, symmetry breaking is sufficient to generate heat current. © 2010 The American Physical Society.||Source Title:||Physical Review E - Statistical, Nonlinear, and Soft Matter Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/96444||ISSN:||15393755||DOI:||10.1103/PhysRevE.81.021111|
