We show that for large values of temperature and dimensionless time, unlike concurrence which vanishes, nonzero discord can still be observed.

- Abstract: We investigate the dynamics of quantum discord and concurrence between two
excitonic qubits placed inside two coupled semiconductor quantum dots
independently interacting with dephasing reservoirs. We explore their behavior
against the dimensionless time and the temperature in both Markovian and
non-Markovian environments. Moreover, we analyze the external electric field
effects and the F\"orster interaction effects on these correlations. We show
that, although the quantum correlations amount is strongly influenced by the
variation of the electric field and the F\"orster interaction, their
non-Markovian behavior is still preserved under the variation of these two
parameters. Furthermore, we show that for large values of temperature and
dimensionless time, unlike concurrence which vanishes, nonzero discord can
still be observed.

We observe a divergence of thermalization rates of quantum matters when the temperature approaches zero.
We find that the quantum coherence and bosonic stimulation of superfluid induces the divergence while the finite temperature and the many-body interactions are suppressing the divergence.

Charge noise in semiconducting quantum dots has been observed to have a 1/f spectrum.
We propose a model in which a pair of quantum dots are coupled to a 2D bath of two level systems.
We find that 1/f electric potential noise spectra at the quantum dots and cross correlation in the noise between the two quantum dots are in qualitative agreement with experiment.

Quantum correlation behaviours in the two-qubit spin squeezing model are studied under the influence of intrinsic decoherence.
We show that the entanglement suffers from intrinsic decoherence and exhibits sudden death, whereas the other measures are more robust against intrinsic decoherence.

Wave-particle duality ascribes mutually exclusive behaviors to quantum systems that cannot be observed simultaneously.
Here, we use quantum information-theoretic tools to derive quantifiers of two properties, which account for the combined influence of path probability and polarization.
The derived quantities can work as probes in the study of open quantum dynamics.

Quantum asymmetry is a physical resource which coincides with the amount of coherence between the eigenspaces of a generator.
We show that the asymmetry may emphincrease as a result of a emphdecrease of coherence inside a degenerate subspace.
