"Microwave generation of stable atmospheric-pressure fireballs in air" Karl D. Stephan, Physical Review E 74, November 2006
"Fireball Ejection from a Molten Hot Spot to Air by Localized Microwaves" Vladimir Dikhhyar and Eli Jerby, PRL 96 20006
"An Observation of Synthetic Ball Lightning" Igor Alexeff et al., IEEE Transactions on Plasma Science, Vol 33 No. 2 April 2005
"Spherical Plasmoids Formed upon the Combustion and Explosion of Nanostructured Hydrated Silicon" S.K. Lazarouk et al., JETP Letters 2006, Vol 84, No. 11
I've got a few more in hand and could go on, but this should be sufficient for a start.
