Performance of autonomous quantum thermal machines: Hilbert space dimension as a thermodynamical resource
Performance of autonomous quantum thermal machines: Hilbert space dimension as a thermodynamical resource
Multilevel autonomous quantum thermal machines are discussed. In particular, we explore the relationship between the size of the machine (captured by Hilbert space dimension) and the performance of the machine. Using the concepts of virtual qubits and virtual temperatures, we show that higher dimensional machines can outperform smaller ones. For …
