DESCRIPTION:Speakers: Roman Zhokhov (IHEP Protvino\, IZMIRAN Troitsk)\nThe
  QCD phase diagram at high baryon density and moderate temperature is expe
 cted to exhibit a rich phase structure beyond the possible first-order tra
 nsition. Inhomogeneous phases\, i. e. phases characterized by spatially mo
 dulated condensates\, is one of the most intriguing options. These phases\
 , such as the chiral density wave or crystalline condensates are studied a
 s a rule using model calculations\, for example\, in the framework of Namb
 u–Jona-Lasinio and quark-meson models. The studies indicate that the inh
 omogeneous region potentially covers the putative critical endpoint and co
 nnects the hadronic and quark-matter phases. Their presence can significan
 tly alter the phase structure and its experimental implications. The statu
 s of inhomogeneous phases will be briefly reviewed and new results in quar
 k matter with isospin and chiral imbalance will be discussed. The studies 
 in effective models have their own problems. So the study of low-dimension
 al models is critical in this context owing to their relative simplicity a
 nd renormalizability. The inhomogeneous phases are thoroughly studied in (
 1+1)-dimensional models. The search for such phases in (2+1)-dimensional m
 odels is a recent endeavor\, and current evidence suggests they are absent
 . We check this implication and then discuss (2+1)-dimensional models with
  one compactified spatial coordinate and study inhomogeneous phases in the
  crossover regime between these two low-dimensional models and found in wh
 at conditions the inhomogeneous phase is realized.\n\nhttps://indico.parti
