SUMMARY:Attoseconds: faster than a New York minute!\, Physics Departme
 nt Colloquium\, Louis F. DiMauro\, The Ohio State University
DESCRIPTION:The genesis of light pulses with attosecond (10-18 seconds
 ) durations signifies a new frontier in time-domain physics. This achi
 evement was recognized by the 2023 Nobel prize in Physics for Agostini
 \, Krausz and L’Huillier. The scientific importance is obvious: the 
 time-scale necessary for probing the motion of an electron(s) in the g
 round state is attoseconds (atomic unit of time  24 as). The availa
 bility of attosecond pulses has allowed\, for the first time\, the stu
 dy of the time-dependent dynamics of correlated electron systems by fr
 eezing the electronic motion\, in essence exploring the structure with
  ultra-fast snapshots\, then following the subsequent evolution using 
 interferometry techniques. This talk will examine the fundamental prin
 ciples\, the underlying physics and the prescription for forming and m
 easuring attosecond light pulses in the laboratory.
