Nose-Hoover thermostat: Difference between revisions

Revision as of 14:11, 29 May 2019

In the approach by Nosé and Hoover^[1]^[2]^[3] an extra degree of freedom is introduced in the Hamiltonian. The heat bath is considered as an integral part of the system and has a fictious coordinate $s$ which is introduced into the Lagrangian of the system. This Lagrangian for an $N$ is written as

${\displaystyle \mathcal{L} = }$
