Topological Phenomena in Trapped Ion Systems
T. Shi, J. I. Cirac
We propose and analyze a scheme to observe topological phenomena with ions in microtraps. We consider a set of trapped ions forming a regular structure in two spatial dimensions an…
Entanglement, fractional magnetization and long-range interactions
Andrea Cadarso, Mikel Sanz, Michael M. Wolf +2
Based on the theory of Matrix Product States, we give precise statements and complete analytical proofs of the following claim: a large fractionalization in the magnetization or th…
Dissipative spin chains: Implementation with cold atoms and steady-state properties
Heike Schwager, J. Ignacio Cirac, Géza Giedke
We propose a quantum optical implementation of a class of dissipative spin systems, including the XXZ and Ising model, with ultra-cold atoms in optical lattices. Employing the moti…
Dissipative Dynamics and Phase Transitions in Fermionic Systems
Birger Horstmann, J. Ignacio Cirac, Géza Giedke
We study abrupt changes in the dynamics and/or steady state of fermionic dissipative systems produced by small changes of the system parameters. Specifically, we consider open ferm…
