微脉泽中作为热机和非热机燃料的多原子量子相干性
Multiatom Quantum Coherences in Micromasers as Fuel for Thermal and Nonthermal Machines
摘要：
在本文中，我们解决的问题：在多大程度上是多原子团簇的量子态准备（之前，他们被注入到微波腔）工具，不仅决定了我们可以操作的机器，但它的性能的定量界限？形象地说，如果多原子团簇是“原油”，问题是：哪种制备团簇的方法是可以提供具有“特定辛烷值”的“汽油”的精炼过程？我们根据原子之间的相干性或量子相关性作为（i）对应于原子状态的非热机器的燃料，其相干性取代或挤压腔场，以及导致其加热;以及（ii）纯粹“可燃”的燃料，即，对应于只允许与场进行热和熵交换的原子状态，并且可以激励适当的热机。我们确定了非常有前途的多原子状态的每种燃料，并提出可行的实验方案，为他们的实施。
英文摘要：
In this paper we address the question: To what extent is the quantum state preparation of multiatom clusters (before they are injected into the microwave cavity) instrumental for determining not only the kind of machine we may operate but also the quantitative bounds of its performance? Figuratively speaking, if the multiatom cluster is the "crude oil", the question is: Which preparation of the cluster is the refining process that can deliver a "gasoline" with a "specific octane"? We classify coherences or quantum correlations among the atoms according to their ability to serve as (i) fuel for nonthermal machines corresponding to atomic states whose coherences displace or squeeze the cavity field, as well as cause its heating; and (ii) fuel which is purely "combustible", i.e., corresponds to atomic states that only allow for heat and entropy exchange with the field and can energize a proper heat engine. We identify highly promising multiatom states for each kind of fuel and propose viable experimental schemes for their implementation.
