A Shielding Property for Thermal Equilibrium States on the Quantum Ising Model
Natália S. Móller, Alberto L. de Paula, Raphael C. Drumond
We show that Gibbs states of non-homogeneous transverse Ising chains satisfy a \emph{shielding} property. Namely, whatever the fields on each spin and exchange couplings between ne…
Spinon and bound state excitation "light cones" in Heisenberg XXZ Chains
A. L. de Paula, H. Bragança, R. G. Pereira +2
We investigate the out-of-equilibrium dynamics after a local quench that connects two spin-1/2 XXZ chains prepared in the ground state of the Hamiltonian in different phases, one i…
Dynamics of entanglement among the environment oscillators of many-body systems
A. L. de Paula, Dagoberto S. Freitas
In this work we extend the discussion that was began in the Ref. [A. L. de Paula Jr., J. G. G. de Oliveira Jr., J. G. Peixoto de Faria, Dagoberto S. Freitas and M. C. Nemes, {\it P…
