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…

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…

Quantum dynamics in high codimension tilings: from quasiperiodicity to disorder
J. Vidal, N. Destainville, R. Mosseri
We analyze the spreading of wavepackets in two-dimensional quasiperiodic and random tilings as a function of their codimension, i.e. of their topological complexity. In the quasipe…
