Quantization and Asymptotic Behaviour of Quantum Random Walk on Integers
Demosthenes Ellinas, Ioannis Smyrnakis
Quantization and asymptotic behaviour of a variant of discrete random walk on integers are investigated. This variant, the walk, has the novel feature that it uses many…
Region Operators of Wigner Function: Transformations, Realizations and Bounds
Demosthenes Ellinas, Ioannis Tsohantjis
An integral of the Wigner function of a wavefunction |psi >, over some region S in classical phase space is identified as a (quasi) probability measure (QPM) of S, and it can be ex…
On Algebraic and Quantum Random Walks
Demosthenes Ellinas
Algebraic random walks (ARW) and quantum mechanical random walks (QRW) are investigated and related. Based on minimal data provided by the underlying bialgebras of functions define…
Asymptotics of Quantum Random Walk Driven by Optical Cavity
Demosthenes Ellinas, Ioannis Smyrnakis
We investigate a novel quantum random walk (QRW) model, possibly useful in quantum algorithm implementation, that achieves a quadratically faster diffusion rate compared to its cla…
Optical Dipole Trapping beyond Rotating Wave Approximation: The case of Large Detuning
Vassilios E Lembessis, Demosthenes Ellinas
We show that the inclusion of counter-rotating terms, usually dropped in evaluations of interaction of an electric dipole of a two level atom with the electromagnetic field, leads…
A discrete nonlinear mass transfer equation with applications in solid-state sintering of ceramic materials
D. T. Hristopulos, L. Leonidakis, A. Tsetsekou
The evolution of grain structures in materials is a complex and multiscale process that determines the material's final properties. Understanding the dynamics of grain growth is a…
