DESCRIPTION:Chiral molecules form a plethora of liquid-crystalline phases\
 , even in equilibrium. Liquid-crystalline phases formed by chiral and acti
 ve agents have features that are however significantly more counterintuiti
 ve. For instance\, while in passive matter\, chirality tends to cloak itse
 lf from the long-wavelength elastic and hydrodynamic properties\, activity
  reveals its effect in cholesteric and chiral columnar phases\, leading to
  unique forms of odd elastic behaviours. The interplay of chirality and ac
 tivity also leads to liquid-crystalline phases without any passive analogu
 e\, such as time liquid crystals. In this talk\, I will demonstrate how th
 e interplay of chirality and activity allows the former to affect dynamic 
 and static properties of ordered states unlike in passive soft materials.
