Ratcheting Heat Flux against a Thermal Bias
arXiv:0804.3630 · doi: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 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 controlled and reversed by suitably tailoring the frequency ( 100 MHz) of the alternating temperature field.
