SUMMARY:Many-body physics with cold Rydberg gases - Matthew Jones (Durham 
 University)

DESCRIPTION:By transiently exciting cold atoms to Rydberg states\, it is p
 ossible to switch the strength of the interatomic interactions by twelve o
 rders of magnitude. These strong\, long range interactions enable the stud
 y of quantum and classical many-body physics. In this talk I will report o
 n recent experimental results from our group in Durham\, where we have cre
 ated a cold Rydberg gas of divalent strontium atoms. We show that the inne
 r valence electron can be used to probe the interactions\, which are media
 ted by the outer Rydberg electron. We also describe how this extra electro
 n can be used to probe and manipulate the cold Rydberg gas to investigate 
 the physics of strongly correlated quantum systems.\n
