DESCRIPTION:Speaker: Quentin Moulard\nhosted by Laszlo Erdös & Jan Maas\nA
 bstract: We study the dimer model on the square grid in a layered random e
 nvironment: the edge weights are constant along each row but are i.i.d. sa
 mpled between rows. This disorder structure is inspired by the celebrated 
 two-dimensional McCoyWu disordered Ising model. The disorder produces dram
 atic effects that I will discuss. First\, we find an essential singularity
  of the free energy (which has no analogue for the pure dimer model)\, whe
 re dimer-dimer correlations decay as exp(-\\sqrt{distance}). Besides\, the
  critical exponent 3/2 (PokrovskyTalapov law) at the liquid-solid transiti
 on remains unchanged\, while at the liquid-gaseous transition it now range
 s continuously between 3/2 and infinity.This is based on a joint work with
  Fabio Toninelli (arXiv:2507.11964).
