Remote spatiotemporal control of local states in thermal lattice

초록

The ability to actively control local states in thermal lattice provides critical insights into nonequilibrium thermodynamics and enables novel approaches to energy management across nano to macroscopic scales. The process of thermalization in thermal lattice is a kind of neighboring interactions due to the media-and path-dependent characteristic of Fourier's diffusion, rendering the significant challenge for remote control of local thermal state. Here we construct the time-independent Hamiltonian of a thermal lattice system with consideration of conduction and convection simultaneously and derive the optimal external command for active control of local thermal states. We implement three thermal targeting control-insulation, synchronization, and fluctuation-by modulating power inputs and precisely monitoring temperature evolution to demonstrate the validity and powerfulness of remote spatiotemporal control of local thermal states. Our work paves the way for remote spatiotemporal control of thermal states and provides efficient alternatives for advanced active thermal management in complex architectures.
