SUMMARY:Quantum Many-Body Phenomena in Coupled Arrays of Cavities - Dr Mic

DESCRIPTION:The increasing level of experimental control over atomic and\n
 optical systems gained in recent years has paved the way\nfor the explorat
 ion of new physical regimes in quantum optics\nand atomic physics. Some of
  these regimes are characterised\nby the appearance of quantum many-body p
 henomena\, originally\nencountered only in condensed-matter physics\, and 
 the possibility\nof experimentally accessing them in a more controlled man
 ner.\nIn this talk I will try to give an overview over recent theoretical\
 nstudies concerning the use of cavity quantum electrodynamics to\ncreate q
 uantum many-body systems.\nBased on recent experimental progress in the fa
 brication\nof arrays of interacting micro-cavities and on their coupling\n
 to atomic-like structures\, several proposals for the realisation of\npara
 digmatic many-body models\, such as the Bose-Hubbard\nand anisotropic Heis
 enberg models have been developed.\nSuch arrays of coupled cavities offer 
 interesting properties as\nsimulators of quantum many-body physics\, inclu
 ding the full\naddressability of individual sites and the accessibility of
 \ninhomogeneous models.
