Formation of helical ion chains
Ramil Nigmatullin, Adolfo del Campo, Gabriele De Chiara +3
We study the nonequilibrium dynamics of the linear to zigzag structural phase transition exhibited by an ion chain confined in a trap with periodic boundary conditions. The transit…
Quantum superpositions of crystalline structures
Jens D. Baltrusch, Cecilia Cormick, Gabriele De Chiara +2
A procedure is discussed for creating coherent superpositions of motional states of ion strings. The motional states are across the structural transition linear-zigzag, and their c…
Entanglement detection in hybrid optomechanical systems
Gabriele De Chiara, Mauro Paternostro, G. Massimo Palma
We study a device formed by a Bose Einstein condensate (BEC) coupled to the field of a cavity with a moving end-mirror and find a working point such that the mirror-light entanglem…
Quantifying, characterizing and controlling information flow in ultracold atomic gases
Pinja Haikka, Suzanne McEndoo, Gabriele de Chiara +2
We study quantum information flow in a model comprising of an impurity qubit immersed in a Bose-Einstein condensed reservoir. We demonstrate how information flux between the qubit…
Detection of entanglement in ultracold lattice gases
Gabriele De Chiara, Anna Sanpera
We propose the use of quantum polarization spectroscopy for detecting multi-particle entanglement of ultracold atoms in optical lattices. This method, based on a light-matter inter…
The bilinear-biquadratic spin-1 chain undergoing quadratic Zeeman effect
G. De Chiara, M. Lewenstein, A. Sanpera
The Heisenberg model for spin-1 bosons in one dimension presents many different quantum phases including the famous topological Haldane phase. Here we study the robustness of such…
Entangling two distant oscillators with a quantum reservoir
Alexander Wolf, Gabriele De Chiara, Endre Kajari +2
The generation of entanglement between two oscillators that interact via a common reservoir is theoretically studied. The reservoir is modeled by a one-dimensional harmonic crystal…
