Compressibility and pressure correlations in isotropic solids and fluids
J. P. Wittmer, H. Xu, P. Polinsak +4
Presenting simple coarse-grained models of isotropic solids and fluids in , and dimensions we investigate the correlations of the instantaneous pressure and its ideal…
Shear-strain and shear-stress fluctuations in generalized Gaussian ensemble simulations of isotropic elastic networks
J. P. Wittmer, I. Kriuchevskyi, J. Baschnagel +1
Shear-strain and shear-stress correlations in isotropic elastic bodies are investigated both theoretically and numerically at either imposed mean shear-stress () or shear-…
Shear modulus of simulated glass-forming model systems: Effects of boundary condition, temperature and sampling time
J. P. Wittmer, H. Xu, P. Polińska +2
The shear modulus G of two glass-forming colloidal model systems in d=3 and d=2 dimensions is investigated by means of, respectively, molecular dynamics and Monte Carlo simulations…
Impulsive correction to the elastic moduli obtained using the stress-fluctuation formalism in systems with truncated pair potential
H. Xu, J. P. Wittmer, P. Polińska +1
The truncation of a pair potential at a distance r_cut is well-known to imply in general an impulsive correction to the pressure and other moments of the first derivatives of the p…
