Entanglement properties of spin models in triangular lattices
M. Moreno-Cardoner, S. Paganelli, G. De Chiara +1
The different quantum phases appearing in strongly correlated systems as well as their transitions are closely related to the entanglement shared between their constituents. In 1D…
A case study of spin- Heisenberg model in a triangular lattice
M. Moreno-Cardoner, H. Perrin, S. Paganelli +2
We study the spin- model in a triangular lattice in presence of a uniaxial anisotropy field using a Cluster Mean-Field approach (CMF). The interplay between antiferromagnetic ex…
Dynamics of the entanglement spectrum in spin chains
G. Torlai, L. Tagliacozzo, G. De Chiara
We study the dynamics of the entanglement spectrum, that is the time evolution of the eigenvalues of the reduced density matrices after a bipartition of a one-dimensional spin chai…
Entanglement Spectrum, Critical Exponents and Order Parameters in Quantum Spin Chains
G. De Chiara, L. Lepori, M. Lewenstein +1
We investigate the entanglement spectrum near criticality in finite quantum spin chains. Using finite size scaling we show that when approaching a quantum phase transition, the Sch…
Probing magnetic order in ultracold lattice gases
G. De Chiara, O. Romero-Isart, A. Sanpera
A forthcoming challenge in ultracold lattice gases is the simulation of quantum magnetism. That involves both the preparation of the lattice atomic gas in the desired spin state an…
Spontaneous nucleation of structural defects in inhomogeneous ion chains
Gabriele De Chiara, Adolfo del Campo, Giovanna Morigi +2
Structural defects in ion crystals can be formed during a linear quench of the transverse trapping frequency across the mechanical instability from a linear chain to the zigzag str…
