|Title:||Ratcheting heat flux against a thermal bias||Authors:||Li, N.
|Issue Date:||2008||Citation:||Li, N., Hänggi, P., Li, B. (2008). Ratcheting heat flux against a thermal bias. EPL 84 (4) : -. ScholarBank@NUS Repository. https://doi.org/10.1209/0295-5075/84/40009||Abstract:||Merely rocking the temperature in one heat bath can direct a steady heat flux from cold to hot against a (time-averaged) non-zero thermal bias in stylized nonlinear lattice junctions that are sandwiched between two heat baths. Likewise, for an average zero-temperature difference between the two contacts a net, ratchet-like heat flux emerges. Computer simulations show that this very heat flux can be manipulated and even reversed by suitably tailoring the frequency (≲100 MHz) of the alternating-temperature field. © Europhysics Letters Association. 2008.||Source Title:||EPL||URI:||http://scholarbank.nus.edu.sg/handle/10635/97759||ISSN:||02955075||DOI:||10.1209/0295-5075/84/40009|
