Nonmonotonic fracture behavior of polymer nanocomposites
Janaina G. de Castro, Rojman Zargar, Mehdi Habibi +5
Polymer composite materials are widely used for their exceptional mechanical properties, notably their ability to resist large deformations. Here we examine the failure stress and…
Free energy of sheared colloidal glasses
M. T. Dang, V. Chikkadi, R. Zargar +4
We develop a free energy framework to describe the response of glasses to applied stress. Unlike crystals, for which the free energy increases quadratically with strain due to affi…
The Boson Peak and Disorder in Hard Sphere Colloidal Systems
Rojman Zargar, John Russo, Peter Schall +2
The Boson peak is believed to be the key to the fundamental understanding of the anomalous thermodynamic properties of glasses, notably the anomalous peak in the heat capacity at l…
Direct Measurement of the Free Energy of Aging Hard-Sphere Colloidal Glasses
Rojman Zargar, Bernard Nienhuis, Peter Schall +1
The nature of the glass transition is one of the most important unsolved problems in condensed matter physics. The difference between glasses and liquids is believed to be caused b…
Dynamical heterogeneity in aging colloidal glasses of Laponite
Sara Jabbari-Farouji, Rojman Zargar, Gerard Wegdam +1
Glasses behave as solids due to their long relaxation time; however the origin of this slow response remains a puzzle. Growing dynamic length scales due to cooperative motion of pa…
Two-sphere low Reynold's propeller
Ali Najafi, Rojman Zargar
A three-dimensional model of a low-Reynold's swimmer is introduced and analyzed in this paper. This model consists of two large and small spheres connected by two perpendicular thi…
