A Novel Route to Calculate the Length Scale for the Glass Transition in Polymers (2006)

Cangialosi, D., Alegria, A., Colmenero, J.

The occurrence of glass transition is believed to be associated to cooperative motion with a growing length scale with decreasing temperature. We provide a novel route to calculate the size of...

A thermodynamic approach to the fragility of glass-forming polymers (2005)

Cangialosi, D., Alegria, A., Colmenero, J.

We have connected the dynamic fragility, namely the rapidity of the relaxation time increase upon temperature reduction, to the excess entropy and heat capacity of a large number of glass-forming...

Scaling out the density dependence of the $\alpha$ relaxation in glassforming polymers (2004)

Alba-Simionesco, C., Cailliaux, A., Alegria, A., Tarjus, G.

We show that the density and temperature dependences of the $\alpha$-relaxation time of several glassforming polymers can be described through a single scaling variable $X=e(\rho)/T$, where $e(\rho)$...

The Spin Glass Transition : Exponents and Dynamics (1998)

Bernardi, L. W., Lemke, N., Mari, P. O., Campbell, I. A., Alegria, A., Colmenero, J.

Numerical simulations on Ising Spin Glasses show that spin glass transitions do not obey the usual universality rules which hold at canonical second order transitions. On the other hand the dynamics...
