DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MathMAC/38/"
 >Solitary cluster waves in driven dense colloids</a>\nby Artem Ryabov as p
 art of Modelling of materials - theory\, model reduction and efficient num
 erical methods (UNCE MathMAC)\n\n\nAbstract\nWe will discuss the static an
 d dynamic states of hard spheres confined in one-dimensional periodic pote
 ntials at high particle densities. Such systems can reside in a mechanical
  equilibrium or in running states characterized by soliton-mediated transp
 ort [1-3]. For weak external driving\, these solitary cluster waves emerge
  in narrow intervals of specific particle sizes. The minimal number of par
 ticles needed to trigger the soliton propagation follows from conditions o
 f mechanical equilibrium and can be determined by a geometric principle of
  minimum residual free space. We further address the number of propagating
  solitons\, their mutual interactions\, the influence of external forcing\
 , and present experimental evidence for such solitary excitations in drive
 n colloidal systems [4].\n\n[1] AP Antonov\, A Ryabov\, P Maass\, Phys. Re
