SUMMARY:Exciton Condensates are Super!\, Physics Department Colloquium
 \, Allan MacDonald \, The University of Texas at Austin
DESCRIPTION:Electronic systems can have a type of order in which coher
 ence is spontaneously established between two distinct groups of elect
 rons.   So far this (particle-hole or exciton condensate) type of orde
 r has been conclusively demonstrated only in double-layer two-dimensio
 nal electron gas systems\, and only in certain strong magnetic field l
 imits.  I will review some of the surprising superfluid transport effe
 cts that have been observed in double-layer exciton condensates\, and 
 speculate on the possibility of engineering similar effects at room te
 mperature either by engineering favorable conditions in van der Waals 
 material bilayers or by designing ferromagnetic materials with appropr
 iate properties.
