Entangled three-qubit states without concurrence and three-tangle.
Lohmayer R, Osterloh A, Siewert J, Uhlmann A. Lohmayer R, et al. Among authors: osterloh a. Phys Rev Lett. 2006 Dec 31;97(26):260502. doi: 10.1103/PhysRevLett.97.260502. Epub 2006 Dec 29. Phys Rev Lett. 2006. PMID: 17280411
We provide a complete analysis of mixed three-qubit states composed of a Greenberger-Horne-Zeilinger state and a W state orthogonal to the former. ...These results highlight intriguing differences compared to the properties of two-qubit mixed states, and may …

Enhancement of pairwise entanglement via Z2 symmetry breaking.
Osterloh A, Palacios G, Montangero S. Osterloh A, et al. Phys Rev Lett. 2006 Dec 22;97(25):257201. doi: 10.1103/PhysRevLett.97.257201. Epub 2006 Dec 18. Phys Rev Lett. 2006. PMID: 17280385
We study the effect of symmetry breaking in a quantum phase transition on pairwise entanglement in spin-1/2 models. We give a set of conditions on correlation functions a model has to meet in order to keep the pairwise entanglement unchanged by a parit …

Avalanche of entanglement and correlations at quantum phase transitions.
Krutitsky KV, Osterloh A, Schützhold R. Krutitsky KV, et al. Among authors: osterloh a. Sci Rep. 2017 Jun 16;7(1):3634. doi: 10.1038/s41598-017-03402-8. Sci Rep. 2017. PMID: 28623315 Free PMC article.
Exact correlation functions of the BCS model in the canonical ensemble.
Amico L, Osterloh A. Amico L, et al. Among authors: osterloh a. Phys Rev Lett. 2002 Mar 25;88(12):127003. doi: 10.1103/PhysRevLett.88.127003. Epub 2002 Mar 11. Phys Rev Lett. 2002. PMID: 11909495
We evaluate correlation functions of the BCS model for a finite number of particles. The integrability of the Hamiltonian relates it with the Gaudin algebra G[sl(2)]. Therefore, a theorem that Sklyanin proved for the Gaudin model, can be applied. Several diagonal an …

Integrable model for interacting electrons in metallic grains.
Amico L, Di Lorenzo A, Osterloh A. Amico L, et al. Among authors: osterloh a. Phys Rev Lett. 2001 Jun 18;86(25):5759-62. doi: 10.1103/PhysRevLett.86.5759. Phys Rev Lett. 2001. PMID: 11415351
The Hamiltonian is integrable by construction since it is a functional of commuting operators; these operators, which therefore are constants of motion of the model, contain the anisotropic Gaudin Hamiltonians. ...We discuss possible applications of this model to a

Quantum many particle systems in ring-shaped optical lattices.
Amico L, Osterloh A, Cataliotti F. Amico L, et al. Among authors: osterloh a. Phys Rev Lett. 2005 Aug 5;95(6):063201. doi: 10.1103/PhysRevLett.95.063201. Epub 2005 Aug 1. Phys Rev Lett. 2005. PMID: 16090948
In the present work we demonstrate how to realize a 1D closed optical lattice experimentally, including a tunable boundary phase twist. ...A mixture of bosonic and/or fermionic atoms can be loaded into the lattice, realizing a generic quantum system of …

Scaling of entanglement close to a quantum phase transition.
Osterloh A, Amico L, Falci G, Fazio R. Osterloh A, et al. Nature. 2002 Apr 11;416(6881):608-10. doi: 10.1038/416608a. Nature. 2002. PMID: 11948343
Classical phase transitions occur when a physical system reaches a state below a critical temperature characterized by macroscopic order. ...Both classical and quantum critical points are governed by a diverging correlation length, although quantum sys …
