Phase transition in the binary mixture of jammed particles with large size dispersity

It has been well established that particulate systems show the jamming transition and critical scaling behaviors associated with it. However, our knowledge is limited to (nearly) monodisperse systems. Recently, a binary mixture of jammed particles large size dispersity was studied, it suggested two distinct phases appeared. Here, we conduct thorough numerical study on this system special focus statistics finite-size effects fraction small participate in rigid network. We present strong evidence appear depending pressure composition species, which are separated by first-order phase transition. In one phases, only jammed, whereas both other phase. also describe diagram pressure-composition plane, where line terminates at point. addition, investigate mechanical properties terms elastic moduli over find discontinuous changes emerge across Remarkably, despite discontinuities, each exhibit identical laws those
