Fig. 1 (IMAGE) Osaka University Caption Shear stress-strain curves of dense colloidal glasses obtained by computer simulations. The initial configurations are created by using the swap algorithm, which allows preparation of very dense, ultra-stable glass states. The system is slightly compressed before application of shear strain.
