Berry Phase Quantum Thermometer [PDF]

, 2013
We show how Berry phase can be used to construct an ultra-high precision quantum thermometer. An important advantage of our scheme is that there is no need for the thermometer to acquire thermal equilibrium with the sample. This reduces measurement times

Impact of engineering renovation on dynamic health risk assessment of mercury in a thermometer enterprise

Frontiers in Public Health, 2022
The occupational health risk assessments (OHRA) of inorganic mercury (Hg) are rarely reported. We conducted an internal and external exposure monitoring of employees in a thermometer enterprise which experienced the renovation of occupational health ...
