Discontinuous thinning in active microrheology of soft complex matter
Discontinuous thinning in active microrheology of soft complex matter
Employing theory and numerical simulations, we demonstrate discontinuous force thinning due to the motion of an external probe in a host medium, which we approximate as structureless. When the driving of the probe exceeds a critical force, the microviscosity of the medium drops abruptly by about an order of magnitude. …
