DESCRIPTION:Arrays of Rydberg atoms have emerged as one of the
  most promising platforms for analogue quantum com
 puting and have already stimulated tremendous prog
 ress in theoretical understanding of quantum phase
  transitions in one dimension. But to what extent 
 can we rely on these platforms to predict new phys
 ics? In this seminar\, I will demonstrate how expe
 riments on Rydberg atoms have inspired the discove
 ry of quantum chiral phase transitions through num
 erical tensor network simulations on classical com
 puters\, and discuss the challenges associated wit
 h their experimental realization. I will outline h
 ow multi-component Rydberg atoms could be used to 
 manipulate the appearance and extent of the novel 
 transition. Finally\, I will briefly discuss the e
 ffect of lattice distortion\, which is unavoidable
  in modern experiments due to a finite width of th
 e optical tweezers\, on the nature of quantum crit
 ical points. This recent study reveals the limitat
 ions of currently available experimental platforms
  and introduces novel theoretical puzzles to be so
 lved.
