- Abstract: The bound entangled state carries noisy entanglement and it is very hard to
distill but the usefulness of bound entangled states has been depicted in
different applications. This article represents a comparative dynamical study
of an open quantum system for one of the bound entangled states proposed by
Bennett et al. The study is conducted under the influence of Heisenberg,
bi-linear bi-quadratic and Dzyaloshinskii-Moriya (DM) interaction. During the
study, an auxiliary qutrit interacts with one of the qutrits of the selected
two qutrit bound entangled state through different interactions. The computable
cross-norm or realignment (CCNR) criterion has been used to detect the bound
entanglement of the state and the negativity has been applied to measure the
free entanglement. From this three-fold study it is observed that, although the
auxiliary qutrit plays a significant role during the interaction, the
probability amplitude of the qutrit does not affect the open quantum system.
Further, it is found that the Dzyaloshinskii-Moriya (DM) interaction performs
better to activate the chosen bound entangled state among all the interactions.

We investigate changes in negativity in terms of anisotropy parameters, gamma, the strength of the external magnetic field applied to the spin chain, eta, the triple interaction strength, alpha.
We examine how these parameters affect the entanglement properties of the system and discuss the implications for quantum information processing and quantum communication protocols.

We explore the control of Aharonov--Bohm (AB) caging via a tunable $U(1)$ gauge field.
In the limit of weak interactions, where caging remains intact, we observe an effective magnetism that arises due to the interaction-driven mixing of degenerate flat-band states.

The paradoxical phenomenon of the quantum Cheshire Cat (qCC) refers to situations where different properties of a particle appear to be localised in different paths of an interferometer.
The localisations are determined qualitatively through conspicuous changes induced by weak interactions.
It is demonstrated that the three properties of neutrons are found separated in different paths in the interferometer.

Two spins (qubits or qutrits) only undergo a coupling-based joint Landau-Majorana-St"uckelberg-Zener (LMSZ) transition when a linear ramp acts upon one of the two spins.
The effects on the quantum dynamics of the two qudits, stemming from the Dzyaloshinskii-Moriya (DM) and dipole-dipole (d-d) interactions, are investigated.
