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…
Nonperturbative renormalization group approach to the Ising model: a derivative expansion at order
L. Canet, B. Delamotte, D. Mouhanna +1
On the example of the three-dimensional Ising model, we show that nonperturbative renormalization group equations allow one to obtain very accurate critical exponents. Implementing…
Discrete non-Abelian gauge theories in two-dimensional lattices and their realizations in Josephson-junction arrays
B. Doucot, L. B. Ioffe, J. Vidal
We discuss real-space lattice models equivalent to gauge theories with a discrete non-Abelian gauge group. We construct the Hamiltonian formalism which is appropriate for their sol…
