Using computer simulations, we show that the localized low frequency normal modes of a
configuration in a supercooled liquid are strongly correlated with the irreversible structural …

We consider the localisation properties of a lattice of coupled masses and springs with
random mass and spring constant values. We establish the full phase diagrams of the …

We study numerically the disorder-induced localization–delocalization phase transitions that
occur for mass and spring constant disorder in a three-dimensional cubic lattice with …

We study localization of elastic waves in two-dimensional heterogeneous solids with
randomly distributed Lamé coefficients, as well as those with long-range correlations with a …

We investigate two one-dimensional tight-binding models with disorder that have extended
states at zero energy. We use exact and partial diagonalisation of the Hamiltonian to obtain …

In this work, a discrete numerical scheme is presented capable of modeling the hysteretic
behavior of 2D structures. Rigid Body Spring Network (RBSN) models that were first …

We use a transfer-matrix method to study the localization properties of vibrations in a'mass
and spring'model with simple cubic lattice structure. Disorder is applied as a box-distribution …
