✦ Synopsis

We report the noise measurements of a very high resolution thermometer which have reached the limit in temperature resolution set by thermodynamics. Our data support the idea of temperature fluctuations in the canonical ensemble. It was interpreted by some that the temperature of a subsystem in the canonical ensemble is the temperature of the reservoir, and should not fluctuate. Such an interpretation is not supported by our observations.

## Abstract An extended system Hamiltonian is proposed to perform molecular dynamics (MD) simulation in the grand canonical ensemble. The Hamiltonian is similar to the one proposed by Lynch and Pettitt (Lynch and Pettitt, J Chem Phys 1997, 107, 8594), which consists of the kinetic and potential ene
