The energy levels and the optical absorption of a circular quantum dot with hard walls are studied in the presence of a static electric field. The results are compared with the case of soft-wall confinement. Calculations show that: (i) the structures

The effect of the Aharonov-Bohm potential on the optical polaron is discussed. In the case of the small magnetic flux the continuous limit is taken and the analytic solution is given. The parameters of the soliton-type solution, such as the height an

A parabolic confining quantum dot system with a hydrogenic impurity is studied with variational approach. The property of its ground state energy is compared with the hard wall model and the non-impurity model, and with those which are treated with p

The effect of the Aharonov-Bohm potential on the acoustical polaron is considered by using the Davydov ansatz. The results show that the height and width of the soliton, the self-trapping energy, the effective mass of the soliton and the deformation

In this paper, two simple models for considering the magnetic responses of the recently synthesized carbon nanotubes (CN) are designed: one is a single tube and the other consists of concentric tubes in bulk material with some distribution of radii.

We have performed analytical calculations and computer simulations to study the persistent currents in one-dimensional normal metal mesoscopic ring in an inhomogeneous magnetic field. In the absence of disorder, the general exact solution is found. I

Based on an exact second quantized Hamiltonian of a noninteracting electron gas in a mesoscopic normal metal ring placed in an inhomogeneous magnetic field of texture structure, we obtain a series of new features of this physical system. The exact en

The effect of electron-phonon coupling on persistent currents in a one-dimensional mesoscopic ring is discussed within a tight-binding model. The results show that the amplitude of the current decreases by a Debye-Waller factor, which does not disapp
