Dissipative Quantum Ising model in a cold atomic spin-boson mixture
Peter P. Orth, Ivan Stanic, Karyn Le Hur
Using cold bosonic atoms with two (hyperfine) ground states, we introduce a spin-boson mixture which allows to implement the quantum Ising model in a tunable dissipative environmen…

Negative refraction with tunable absorption in an active dense gas of atoms
P. P. Orth, R. Hennig, C. H. Keitel +1
Applications of negative index materials (NIM) presently are severely limited by absorption. Next to improvements of metamaterial designs, it has been suggested that dense gases of…
