We consider two interacting systems when one is treated classically while the other system
remains quantum. Consistent dynamics of this coupling has been shown to exist, and …

The measurement of small mass and force is as pertinent now as it was in 1923 when EM
Eden and CG Eden published their article titled'Two machines for rapidly weighing loads of …

A tabletop-sized Kibble balance (KIBB-g1) designed to directly realize mass at the gram-
level range with uncertainties on the order of parts in 10 6 has been developed at the …

The redefinition of mass adopted in November 2018 and implemented from 20 May 2019, ie
World Metrology Day, eliminated the artefact-based approach dependent upon the …

从2019 年5 月20 日起, 新国际单位制(international system of units, SI) 在全世界正式启用.
在新的单位体系下, 7 个SI 基本单位首次实现了全部采用基于基本物理常数的定义 …

This paper presents a novel dynamic torque generator based on the principle of a Kibble
balance. A generator is developed to dynamically calibrate torque-measuring devices …

In the present study, we developed a torque generating machine using an electromagnetic
force based on the principle of the Kibble balance method in order to realize a nano-torque …

The Kibble balance has become one of the major instruments for realizing the mass unit, the
kilogram, in the revised international system of units (SI). Researchers at about a dozen …

Seit dem 20. Mai 2019 gilt das neue Internationale Einheitensystem SI. Dies stellt eine Zäsur
in der Geschichte der Einheiten dar, denn von nun an sind alle 7 Basiseinheiten durch …

We develop autonomous classical-quantum dynamics by providing formalism and tools to
study effective theories of interacting classical and quantum systems. We find the most …
