Exact solution of a family of staggered Heisenberg chains with conclusive pretty good quantum state transfer
Pablo Serra, Alejandro Ferrón, Omar Osenda
We construct the exact solution for a family of one-half spin chains explicitly. The spin chains Hamiltonian corresponds to an isotropic Heisenberg Hamiltonian, with staggered exch…
Understanding the propagation of excitations in quantum spin chains with different kind of interactions
Alejandro Ferrón, Pablo Serra, Omar Osenda
The dynamical behaviour of the quantum state of different quantum spin chains, with designed site dependent interaction strengths, is analyzed when the initial state belongs to the…
Pretty good quantum state transfer on isotropic and anisotropic Heisenberg spin chains with tailored site dependent exchange couplings
Pablo Serra, Alejandro Ferrón, Omar Osenda
Using a global optimization algorithm we obtain spin chains with site-dependent exchange coefficients which allow almost perfect quantum state transfer between the extremes of the…
Convexity properties of superpositions of degenerate bipartite eigenstates
Natalia Giovenale, Federico M. Pont, Pablo Serra +1
The entanglement content of superpositions of pairs of degenerate eigenstates of a bipartite system are considered in the case that both are also eigenstates of the component o…
Phase transitions, order by disorder and finite entropy in the Ising antiferromagnetic bilayer honeycomb lattice
F. A. Gómez Albarracín, H. D. Rosales, Pablo Serra
We present an analytical and numerical study of the Ising model on a bilayer honeycomb lattice including interlayer frustration and coupling with an external magnetic field. First,…
Simultaneous Orientational and Conformational Molecular Dynamics in Solid (1,1,2)-Trichloroethane
Michela Romanini, Efstratia Mitsari, Pragya Tripathi +4
The molecular dynamics in the ambient-pressure solid phase of (1,1,2)-trichloroethane is studied by means of broadband dielectric spectroscopy and molecular dynamics simulations. T…
