The need to perform large-scale molecular dynamics simulations of radiation defects in ferritic steels has stimulated the recent development of a 'magnetic' interatomic potential for body-centred cubic alpha-iron [1,2]. Here we describe the first applicati ...
Almost half of the proteome of living organisms is constituted of metalloproteins. Unfortunately, the ability of the current generation of molecular dynamics pairwise-additive forcefields to properly describe metal pockets is severely lacking due to the in ...
In order to apply the molecular dynamics (MD) method to simulate modulated phases in organic materials, a compensating external pressure tensor is proposed to compensate for the deficiencies of the force field applied in the simulation. MD can well reprodu ...
The electrostatic continuum solvent model developed by [Fattebert and Gygi J. Comput. Chem. 23, 662 (2002); Int. J. Quantum Chem. 93, 139 (2003)] is combined with a first-principles formulation of the cavitation energy based on a natural quantum-mechanical ...
Molecular dynamics (MD) simulations are performed to assess the primary damage due to high-energy neutron irradiation in bcc tungsten. For short-range interactions two different universal potentials are used, while for long-range interactions, two empirica ...
Molecular dynamic calculations of pullout in multiwall carbon nanotubes (CNTs) demonstrate that inner walls with fractured ends have pullout forces similar to3-4 times larger than those for capped ends, due to deformation of the fractured end, quantitative ...
We present a fully Hamiltonian and computationally efficient scheme to include the electrostatic effects due to the classical environment in a Car-Parrinello mixed quantum mechanics/mol. mechanics (QM/MM) method. The polarization due to the MM atoms close ...
We propose a definition for the dipole of an individual molecule in a molecular solid or fluid. This problem is currently dealt with by partitioning-according to some prescription-the continuous electron density of the condensed phase. Instead, here we foc ...
The combination of time-dependent d. functional theory (TDDFT) for the description of excited states with a hybrid quantum mechanics/mol. mechanics (QM/MM) approach enables the study of photochem. processes in complex environments. Here, we present a short ...
In a recent work [Laio, A., VandeVondele, J., Rothlisberger, U. J. Phys. Chem. B 2002 106, 7300] a novel method has been proposed to define dynamical electrostatic potential derived (D-RESP) charges for systems described within a quantum mechanics/mol. mec ...
