Conformational properties of strictly two-dimensional equilibrium polymers
J. P. Wittmer, A. Cavallo, A. Johner
Two-dimensional monodisperse linear polymer chains are known to adopt for sufficiently large chain lengths and surface fractions compact configurations with fractal perimet…
On inequalities of shear modulus contributions in disordered elastic bodies
J. P. Wittmer, H. Xu
We investigate generic inequalities of various contributions to the shear modulus in ensembles of amorphous elastic bodies. We focus first on a simple elastic network model wit…
Isotropic tensor fields in amorphous solids: Correlation functions of displacement and strain tensor fields
J. P. Wittmer
Generalizing recent work on isotropic tensor fields in isotropic and achiral condensed matter systems from two to arbitrary dimensions we address both mathematical aspects assuming…
Strain correlation functions in isotropic elastic bodies: Large wavelength limit for two-dimensional systems
J. P. Wittmer, A. N. Semenov, J. Baschnagel
Strain correlation functions in two-dimensional isotropic elastic bodies are shown both theoretically (using the general structure of isotropic tensor fields) and numerically (usin…
Correlations of tensor field components in isotropic systems with an application to stress correlations in elastic bodies
J. P. Wittmer, A. N. Semenov, J. Baschnagel
Correlation functions of components of second-order tensor fields in isotropic systems can be reduced to an isotropic forth-order tensor field characterized by a few invariant corr…
Spatial correlation functions for non-ergodic stochastic processes of macroscopic system
J. P. Wittmer, A. N. Semenov, J. Baschnagel
Focusing on non-ergodic macroscopic systems we reconsider the variances of time averages time-series. The total variance (direct average over all time-series) is known to be the su…
