Spins dans un bain de bosons : des phénomènes exotiques au calcul quantique

Karyn Le Hur (Physics Department, Yale University, New Haven - USA)

Spins in a bosonic environment provide an ideal system to address important concepts in quantum mechanics and many-body physics such as quantum entanglement, decoherence, dissipation effects at a quantum phase transition, and quantum computation. In this talk, we thoroughly discuss those issues starting from well-defined Hamiltonians, and we suggest realizations of those ideas in solid- state devices and cold-atomic systems.
