Computer Simulation Study of the Levy Flight Process

Random walk simulation of the Levy flight shows a linear relation between the mean square displacement and time. We have analyzed different aspects of this linearity. It is shown that the restriction of jump length to a maximum value (lm) affects the diffusion coefficient, even though it remains constant for lm greater than 1464. So, this factor has no effect on the linearity. In addition, it is shown that the number of samples does not affect the results. We have demonstrated that the relation between the mean square displacement and time remains linear in a continuous space, while continuous variables just reduce the diffusion coefficient. The results are also implied that the movement of a levy flight particle is similar to the case the particle moves in each time step with an average length of jumping . Finally, it is shown that the non-linear relation of the Levy flight will be satisfied if we use time average instead of ensemble average. The difference between time average and ensemble average results points that the Levy distribution may be a non-ergodic distribution.Comment: 14 pages, 7 figure

Simple Pulses for Universal Quantum Computation with a Heisenberg ABAB Chain

Recently Levy has shown that quantum computation can be performed using an ABAB.. chain of spin-1/2 systems with nearest-neighbor Heisenberg interactions. Levy notes that all necessary elementary computational `gates' can be achieved by using spin-resonance techniques involving modulating the spin-spin interaction strength at high frequency. Here we note that, as an alternative to that approach, it is possible to perform the elementary gates with simple, non-oscillatory pulses.Comment: 3 pages including 2 fig

A Neuron Model with Variable Ion Concentrations

Many neuron models exist, but usually the voltage is the central feature of those models. Recently interest in long-term potentiation (LTP) has surged, due to the fact that it is linked to learning. It has been shown that LTP is accompanied by an increase of the internal calcium concentration. Thus models with variable calcium concentration have been proposed. Since the calcium concentration is very low, this has a negligible effect on the membrane potential. In the present model all ion concentrations are variable due to ionic current and due to ion pumps. It is shown that this significantly increases the complexity of neural processing, and thus variable ion concentrations cannot be ignored in neurons with high firing frequency, or with very long depolarizations.Air Force Office of Scientific Research (F49620-92-J-0225, F49620-92-J-0334
