One of the key issues related to studies in microscale heat transfer is the ability to measure temperature at small scales. In the recent past, rapid and signi cant progress has enabled temperature measurements to be made with unprecedented high spatial and temporal resolutions. This has allowed heat transfer research to enter a new regime which was previously inaccessible. This article review...
We demonstrate fluorescence thermometry techniques with sensitivities approaching 10 mK · Hz(-1/2) based on the spin-dependent photoluminescence of nitrogen vacancy (NV) centers in diamond. These techniques use dynamical decoupling protocols to convert thermally induced shifts in the NV center's spin resonance frequencies into large changes in its fluorescence. By mitigating interactions with n...
We demonstrate spin gradient thermometry, a new general method of measuring the temperature of ultracold atoms in optical lattices. We realize a mixture of spins separated by a magnetic field gradient. Measurement of the width of the transition layer between the two spin domains serves as a new method of thermometry which is observed to work over a broad range of lattice depths and temperatures...
