DESCRIPTION:The most fundamental plasma is the quantum vacuum\, but it rema
 ins largely inaccessible to experiments because of the energy scales invol
 ved. The minimum temperature required to “ionize” the vacuum is equiva
 lent to the mass of an electron-positron pair\, 1 MeV\, or about 1010K. On
 e way to imagine creating an e+e- plasma out of “nothing” is through t
 unnel ionization of the vacuum by a laser\; but simple scaling shows that 
 the intensity required to reach the tunneling threshold must be more than 
 1029 W/cm2\, which has been called the “Schwinger threshold”. This tal
 k will introduce the experimental methods we will use to reach this regime
 \, and what we might expect to find.\n\nCo-sponsored by: MIPSE\n\nSpeaker(
