Alternating Differential Scanning Calorimetric (ADSC) studies show that Se rich As<Subscript>20</Subscript>Se<Subscript>80-x</Subscript>Ag<Subscript>x</Su bscript> (0 ≤ x ≤ 15) glasses exhibit two endothermic glass transitions and two exothermic crystallization peaks; the observed thermal behavior has been understood on the basis that As<Subscript>20</Subscript>Se<Subscript>80-x</Subscript>Ag<Subscript>x </Subscript> glasses...</subscript></subscript></subscript><//su></subscript></subscript></subscript>

We study the intermittent behavior of the energy decay and the linear magnetic response of a glassy system during isothermal aging after a deep thermal quench, using the Edward-Anderson spin glass model as a paradigmatic example. The large intermittent changes in the two observables occur in a...

We study thermal convection in a colloidal glass of Laponite in formation. Low concentration preparation are submitted to destabilizing vertical temperature gradient, and present a gradual transition from a turbulent convective state to a steady conductive state as their viscosity increases. The...

Finite size effects on dynamical heterogeneity are studied in liquid silica with Molecular Dynamics simulations using the BKS potential model. When the system size decreases relaxation times are found to increase in accordance with previous results in finite-size simulations and confined...

Dynamical heterogeneities (DH) in low density liquid SiO<Subscript>2</Subscript> have been investigated by molecular dynamics (MD) method. Simulations were done in the basic cube under periodic boundary conditions containing 3000 particles with the pair interatomic potentials, which have a weak electrostatic...</subscript>
