Mechanical pulses show up in several biological processes, including embryo development and wound healing, among others. Given this, several studies have been done on this subject, including physical models. However, most of the models consider a homogeneous system, as they are more interesting on other things. Which means there is a lack of systematic studies on the role of heterogeneity, in particular, “tunable” or “controlled” heterogeneity. This internship project will consider a continuum model, derived as a coarse-graining of a model where there are current preliminary results which show disorder may not always be a hindrance, but may in some cases, aid in effective propagation of pulses. In this limit, we are particularly interested in the limit of strong couplings (which to be honest are not quite biological, but are relevant to equivalent physical systems) where pulses propagate across the entire system and exhibit wavelike properties.
