We have investigated the one dimensional Fe/Pd, Fe/Cu, Fe/Ag, and Fe/Au multilayered nanowire systems by using first principles density functional theory. Our study reveals a gain in the binding energies of these heterostructures regardless of nature of the spacer. We have identified the...

We investigate the lifetime distribution P(τ,t) in one and two dimensional coarsening processes modelled by Ising–Glauber dynamics at zero temperature. The lifetime τ is defined as the time that elapses between two successive flips in the time interval (0,t) or between the last flip and the...

We consider two coupled Duffing oscillators with the coexistence of four attractors. Switching between the coexisting attractors by noises is investigated. Three types of noises such as Gaussian, amplitude dependent and dichotomous are used. We observed noise-induced extrinsic intermittency....

We consider random walks, starting at the site i = 1, on a one-dimensional lattice segment with an absorbing boundary at i = 0 and a reflecting boundary at i = L. We find that the typical value of first passage time (FPT) is independent of system size L, while the mean value diverges linearly...

Faxen's theorem for the force and torque on a sphere moving in a simple fluid is generalized to the case where the fluid possesses internal rotation.

We consider a random walk in discrete time (n = 0, 1, 2, …) on a square lattice of finite width in the y-direction, i.e., {j, m | j ϵ Z, m = 1, 2, 3, …, N}. A myopic walker at (j,1) or (j, N) jumps with probability 13 to any of the available nearest-neighbor sites at the end of a time step....
