Purity as a witness for initial system-environment correlations in open-system dynamics
D. Z. Rossatto, T. Werlang, L. K. Castelano +2
We study the dynamics of a two-level atom interacting with a Lorentzian structured reservoir considering initial system-environment correlations. It is shown that under strong syst…
Spotlighting quantum critical points via quantum correlations at finite temperatures
T. Werlang, G. A. P. Ribeiro, Gustavo Rigolin
We extend the program initiated in [T. Werlang et al., Phys. Rev. Lett. 105, 095702 (2010)] in several directions. Firstly, we investigate how useful quantum correlations, such as…
Quantum behavior of a many photons cavity field revealed by quantum discord
D. Z. Rossatto, T. Werlang, E. I. Duzzioni +1
We investigate the quantum-to-classical crossover of a dissipative optical cavity mode based on measurement of the correlations between two atoms which do not interact with each ot…
