The central result is an ingenious proof that the local temperature and voltage measurement in a nonequilibrium system of fermions exists and is unique, placing the concept of local temperature on a rigorous mathematical footing for the first time. As an intermediate step, a proof of the positivity of the Onsager matrix of linear response theory is given -- a statement of the second law of thermodynamics that had lacked an independent proof for 85 years. A new experimental method to measure the local temperature of an electron system using purely electrical techniques is also proposed, which could enable improvements to the spatial resolution of thermometry by several orders of magnitude. Finally, a new mathematically-exact definition for the local entropy of a quantum system in a nonequilibrium steady state is derived. Several different measures of the local entropy are discussed, relating to the thermodynamics of processes that a local observer with varying degrees of information about the microstates of the system could carry out, and it is shown that they satisfy a hierarchy of | | 出版日期 | Book 2019 | | 关键词 | nonequilibrium quantum thermodynamics; Onsager matrix; second law of thermodynamics; local entropy in q | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-030-33574-8 | | isbn_softcover | 978-3-030-33576-2 | | isbn_ebook | 978-3-030-33574-8Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer Nature Switzerland AG 2019 |
