Thermostat molecular dynamics
In classical molecular dynamics, simulations are done in the microcanonical ensemble; a number of particles, volume, and energy have a constant value. In experiments, however, the temperature is generally controlled instead of the energy. The ensemble of this experimental condition is called a canonical … Visa mer The Nosé–Hoover thermostat is a deterministic algorithm for constant-temperature molecular dynamics simulations. It was originally developed by Nosé and was improved further by Hoover. Although the heat … Visa mer In the approach of Nosé, a Hamiltonian with an extra degree of freedom for heat bath, s, is introduced; where g is the … Visa mer • Berendsen and Nosé-Hoover thermostats • A simple (c++) implementation of the Nosé-Hoover chains thermostat Visa mer Webb13 mars 2024 · Corresponding thermostat parameters are identified, which in principle allow to sample arbitrarily close to canonical equilibrium.
