Generalized valence bond molecular dynamics at constant temperature

The Nose! ± Hoover chain thermostat of Martyna, Klein and Tuckerman has been adapted to work with our generalized valence bond ab initio molecular dynamics (AIMD) method, allowing us to perform AIMD in the canonical ensemble (constant number of particles, temperature, and volume). The canonical ensemble is ideal for simulated annealing, which can be used to ® nd global potential energy minima. ...

Molecular Basis of Activity Coefficient (isobaric- Isothermal Ensemble Approach)

Mansoori, G.A., 1980. Molecular basis of activity coefficient (Isobaric-isothermal ensemble approach). Fluid Phase Equilibria, 4: 61-69. Through the application of isobaric-isothermal (NPT) ensemble theory, molecular relations for thermodynamic properties of mixtures are derived with pressure and temperature as the independent variables. Use of the NPT-ensemble approach has made it possible to ...

Molecular Dynamics at Constant Pressure: Allowing the System to Control Volume Fluctuations via a "Shell" Particle

Since most experimental observations are performed at constant temperature and pressure, the isothermal-isobaric (NPT ) ensemble has been widely used in molecular simulations. Nevertheless, the NPT ensemble has only recently been placed on a rigorous foundation. The proper formulation of the NPT ensemble requires a “shell” particle to uniquely identify the volume of the system, thereby avoiding...

Rigid-body dynamics in the isothermal-isobaric ensemble: A test on the accuracy and computational efficiency

We have developed a time-reversible rigid-body (rRB) molecular dynamics algorithm in the isothermal-isobaric (NPT) ensemble. The algorithm is an extension of rigid-body dynamics [Matubayasi and Nakahara, J Chem Phys 1999, 110, 3291] to the NPT ensemble on the basis of non-Hamiltonian statistical mechanics [Martyna, G. J. et al., J Chem Phys 1994, 101, 4177]. A series of MD simulations of water ...
