Symmetry and size effects on energy and entanglement of an exciton in coupled quantum dots

“…Moreover, they are very useful because of their potential applications not only in quantum device design, but also in the currently active field of quantum information processing. [4][5][6][7] It has been proposed that quantum bits (qubits) can be represented by either electron spin states [8][9][10] or exciton states. [11,12] Since the entanglement of qubits plays an important role in quantum communication and quantum computation, it is essential to study entanglement in these systems.…”

A quantum pseudodot system with two-dimensional pseudoharmonic potential under external magnetic and AB flux fields

“…It is well-known that factors such as impurity, electric and magnetic fields, pressure, and temperature play important roles in the electronic, optical and transport properties of lowdimensional semiconductor nanostructures [4,[27][28][29][30][31][32]. Hence, many works in 2D quantum dots and semiconductors are studied under the influence of external magnetic field [33][34][35][36][37][38]. For example, the set of energy eigenstates of a 2D anisotropic harmonic potential in a uniform magnetic field is found [33].…”

“…The binding energy of a hydrogenic impurity in self-assembled double quantum dots is calculated via the finite-difference method. The variation in binding energy with donor position, structure parameters and external magnetic field is studied [38].…”
