Recently, entropy measurements of quantum dots were demonstrated based on charge sensitivity. These experiments require temperature variations, and extract entropy changes due to gate voltage variations using Maxwell relations. In addition to describing ongoing experimental puzzles, I will discuss new directions that these methods open, such as measurements of fractional entropy in frustrated Kondo systems, in fractional quantum Hall states, and the possibility to detect a decoherence induced phase transition in quantum dots.
