Abstract:
The binding energy of a shallow hydrogenic impurity of a spherical quantum dot confined by harmonic oscillator-like and by rectangular well-like potentials, using a variational procedure within the effective mass approximation, has been determined. The calculations of the binding energy of the donor impurity as a function of the system geometry, and the donor impurity position have been investigated. The binding energy of shallow donor impurity depends not only on the quantum confinements but also on the impurity position. Our results reveal that (i) the donor binding energy decreases as the d

Abstract:
A relativistic harmonic confinement model for quarks and a similar current confinement model for gluons have been used to obtain an equation of state for quark-gluon plasma. Such models may be deduced from QCD under certain approximations, by considering small quantum fluctuations about a background field. At high temperatures a T7 dependence of pressure and energy density is obtained with relativistic harmonic mode of confinement.

Abstract:
This work deals with the key constituent behind the existence of superfluid states in ultracold fermionic gases confined in a harmonic trap in 2D, namely, the formation of Cooper pairs in the presence of a Fermi sea in inhomogeneous confinement. For a set of finite-range models representing particle–particle interaction, we first ascertain the simultaneity of the emergence of bound states and the divergence of the s-wave scattering length in 2D as a function of the interaction potential parameters in free space. Then, through the analysis of two particles interacting in 2D harmonic confinement

Abstract:
In the present study, the influence of spatial confinement on the bond length as well as dipole moment, polarizability and (hyper)polarizabilities of HeH+ ion was analyzed. The effect of spatial confinement was modelled by cylindrically symmetric harmonic oscillator potential, that can be used to mimic high pressure conditions. Based on the conducted research it was found that the spatial confinement significantly affects the investigated properties. Increasing the confinement strength leads to a substantial decrease of their values. This work may be of particular interest for astrochemistry a

Abstract:
High harmonic generation (HHG) in solids has two main applications. First, HHG is an all-solid-state source of coherent attosecond very ultraviolet (VUV) radiation. As such, it presents a promising source for attosecond science. The ultimate goal of attosecond science is to make spatially and temporally resolved movies of microscopic processes, such as the making and breaking of molecular bonds. Second, the HHG process itself can be used to spatially and temporally resolve fast processes in the condensed matter phase, such as charge shielding, multi-electron interactions, and the dynamics and

Abstract The Penning trap is identical to the Paul trap as regards its mechanical configuration; it consists of a three-electrode structure with two end-cap electrodes and a ring electrode, as shown in Fig. 3.1. The crucial difference from the Paul trap is that the Penning trap does not use a radiofrequency field, and in its place uses a uniform magnetic field; the field direction is usually taken along the positive z-axis of the trap. Further, the end-cap electrodes are biased with a positive de voltage (for positive ion confinement) with respect to the ring electrode. Due to the de biasing p

Abstract:
The thermodynamic properties of a supersymmetric (SUSY) oscillator are analyzed within the framework of the canonical ensemble. Analytical expressions for the heat capacity and entropy are derived and subsequently studied in their asymptotic limits. It is demonstrated that the specific heat of the SUSY oscillator adheres to the third law of thermodynamics at low temperatures and satisfies the classical equipartition theorem in the high-temperature regime. This occurs despite the presence of a fermionic component, represented as a two-level system, within the SUSY oscillator. Notably, the speci
