MOBILITY EDGES IN ONE DIMENSIONAL DISORDERED AHARONOV-BOHM RINGS

By analyzing the dependence of the inverse participation ratio on Aharonov-Bohm flux, energy, disorder strength and system size, we find that all states in the ring are delocalized in the weak disorder limit. The states lying deeply in the band tails will undergo a continuous delocalization-localiza[r]

A general relationship for velocity, acceleration, and time has again been obtained from a graph. Notice that this equation was also derived algebraically from other motion equations in Motion Equations for Constant Acceleration in One Dimension .

We address finding solutions y ∈ Ꮿ 2 (R + ) of the special (linear) ordinary di ff erential equation xy ( x ) + ( ax 2 + b ) y ( x ) + ( cx + d ) y ( x ) = 0 for all x ∈ R + , where a , b , c , d ∈ R are constant parameters. This will be achieved in three special cases via separation and a p[r]

Having obtained the eigenenergy diagram of the unperturbed system, we now turn our attention to the exact system which is described by the time-dependent Hamiltonian in Eq. (5.1). As demonstrated for the two-level system in Sec. 4.3, in order[r]

8.9 SUMMARY
An introduction to dislocation strengthening mechanisms has been pre- sented in this chapter. Strengthening was shown to occur by the use of defects (point defects, surface defects and volume defects in the restriction of dislocation motion in engineering alloys. A[r]

The most common non-conservative force in Equation 7.17 is, however, completely valid mechanics is that of friction. When friction is since it was derived by integrating the equations present in a system, processes[r]

Check the answer to see if it is reasonable: Does it make sense? This final step is extremely important—the goal of physics is to accurately describe nature. To see if the answer is reasonable, check both its magnitude and its sign, in addition to its units. Your judgment will impr[r]

In the second part, we consider the problem of maintaining a dictionary that supports successor searches during a one-dimensional walk on a cycle. We show how to achieve linear space and constant expected time for a random walk. If the walk is adversarial, we can achieve a simil[r]

The calculations of the electronic structure of the closed-tip CNTs with finite length suggest that largely localised orbitals exist at the tip (mainly at the five- membered rings) with energies close to the Fermi energy [47]. However, considering the fact that electrons are[r]

Most solids are crystalline and diffusion occurs by atomic hops in a lattice. The most important point is that a separation of time scales exists between the elementary jump process of particles between neighbouring lattice sites and the succession of steps that lead to macroscopic diffusion. T[r]

Using Greens function method and the equation of motion approach, we have investigated the electronic transport properties of an Aharonov-Bohm AB ring in the presence of a magnetic field[r]

When a body is continuous before deformation, it should remain continuous after defor- mation. In other words, no cracks or gaps should appear in the body and no part should overlap another due to deformation. Thus, the displacement field must be continuo[r]

As the data sets resulting from SPH simulations typically contain a multitude of physical variables, it is desirable that visualization methods take into account the entire multi-field volume data rather than concentrating on one variable. We presented a visualization approach based on surface[r]
