- Abstract: We study the skew information-based coherence of quantum states and derive
explicit formulas for Werner states and isotropic states in a set of autotensor
of mutually unbiased bases (AMUBs). We also give surfaces of skew
information-based coherence for Bell-diagonal states and a special class of X
states in both computational basis and in mutually unbiased bases. Moreover, we
depict the surfaces of the skew information-based coherence for Bell-diagonal
states under various types of local nondissipative quantum channels. The
results show similar as well as different features compared with relative
entropy of coherence and l1 norm of coherence.

We identify two different classes: the near edge physics of sparse'' and the near edge of dense'' chaotic systems.
The distinction lies in the ratio between the number of a system's random parameters and its Hilbert space dimension.
While the two families share identical spectral correlations at energy scales comparable to the level spacing, the density of states and its fluctuations near the edge are different.

Local quantum measurements do not simply disentangle degrees of freedom, but may actually strengthen the entanglement in the system.

We find that the m-separability and k-partite entanglement of a multipartite quantum system is correlated with quantum coherence of the same with respect to complete orthonormal bases.
We show that the geometric measure of m-inseparable entanglement of a multipartite quantum state is equal to the square of minimum fidelity-based quantum coherence of the state with respect to complete orthonormal bases.

We characterize this decay using quantum speed limits on the flow of $kappa$, illustrate our results with a model of hard-core anyons, and discuss possible experiments in quantum simulation.

For one-dimensional systems we find very precise estimations of the ground-state energies and the radial distribution functions of the particles.
In two dimensions we obtain good estimations of the ground-state energies, comparable to results obtained from more conventional methods.
