In c\phantom\rule00exa\phantom\rule00exl\phantom\rule00exo\phantom\rule00exr\phantom\rule00exi\phantom\rule00ext\phantom\rule00exr\phantom\rule00exo\phantom\rule00exn\phantom\rule00exi\phantom\rule00exc\phantom\rule00exs, nanoscale heat flow can be not merely managed, but exploited. For example, the authors find that as the amount of quantized flux passing through a SQUID's loop changes, the temperature in one of its branches suddenly jumps, so that in sweeping the magnetic field back and forth, a hysteretic path results. This device can be easily implemented using standard nanofabrication techniques, and, according to its hysteretic switching behavior, could promptly find applications as a temperature-based superconducting memory element, a quantum sensor, or an energy harvester to support nanocircuitry.
