human’s disregard to nature and consequently his living environment’s distance from natural endowments and potentials have caused many problems. human’s living spaces are less desirable for him, and have destroyed his comfort in many cases, as man-made things. in this regard, public open spaces in residential areas can be mentioned because they are usually considered among the most vulnerable s...

Quantum and classical correlations are studied for Werner-Like States of two-qubit cavity system interacting with a thermal reservoir. Starting from Werner-like states, we have shown that entanglement sudden death and decay of both the quantum discord and classical correlation are accelerated by the different factors: thermal photons, cavity decay and the purity of the initial state. By these f...
