Entanglement in a first order quantum phase transition
J. Vidal, R. Mosseri, J. Dukelsky
The phase diagram of spins 1/2 embedded in a magnetic field mutually interacting antiferromagnetically is determined. Contrary to the ferromagnetic case where a second order quantu…

Two and Three Qubits Geometry and Hopf Fibrations
Remy Mosseri
This paper reviews recent attempts to describe the two- and three-qubit Hilbert space geometries with the help of Hopf fibrations. In both cases, it is shown that the associated Ho…

Entanglement in a second order quantum phase transition
J. Vidal, G. Palacios, R. Mosseri
We consider a system of mutually interacting spin 1/2 embedded in a transverse magnetic field which undergo a second order quantum phase transition. We analyze the entanglement pro…
