DESCRIPTION:Laser spectroscopy is a technique of immense value
  in atom optics as\nrecognised with last year's No
 bel Prize for Physics. Can it be applied\nto an ar
 tificial atom in the solid state\, a quantum dot? 
 In order to\nremove the inhomogeneous broadening i
 t is essential to attempt these\nexperiments on ju
 st a single quantum dot\, a challenging enterprise
 . We\nhave now succeeded in this mission. The talk
  presents laser spectroscopy\non a single quantum 
 dot presenting the detection scheme\, an exchange\
 ninteraction which we can turn on and off simply w
 ith a bias voltage\, and\nthe effects of both elec
 tron and hole tunneling.\n\n
