Ballistic Spin Injection and Detection in Fe/Semiconductor/Fe Junctions [PDF]
, 2002 We present {\it ab initio} calculations of the spin-dependent electronic transport in Fe/GaAs/Fe and Fe/ZnSe/Fe (001) junctions simulating the situation of a spin-injection experiment.

A probabilistic representation of constants in Kesten's renewal theorem [PDF]
, 2007 The aims of this paper are twofold. Firstly, we derive some probabilistic representation for the constant which appears in the one-dimensional case of Kesten's renewal theorem. Secondly, we estimate the tail of some related random variable which plays an

Ballistic transport: A view from the quantum theory of motion
, 1994 Ballistic transport of electrons through a quantum wire with a constriction is studied in terms of Bohm's interpretation of quantum mechanics, in which the concept of a particle orbit is permitted.

Crossover from Diffusive to Ballistic Transport in Periodic Quantum Maps [PDF]
, 2003 We derive an expression for the mean square displacement of a particle whose motion is governed by a uniform, periodic, quantum multi-baker map. The expression is a function of both time, $t$, and Planck's constant, $\hbar$, and allows a study of both ...

Ballistic impact response of resistance-spot-welded (RSW) double-layered plates for Q&P980 steel
Defence Technology, 2022 Ballistic impact response of resistance-spot-welded (RSW) double-layered (2 × 1.6 mm) plates (190 mm × 150 mm) for Q&P980 steel impacted by a round-nosed steel bullet (12 mm diameter and 30 mm length) was investigated by using gas gun and high-speed ...

Quasiballistic correction to the density of states in three-dimensional metal
, 1999 We study the exchange correction to the density of states in the three-dimensional metal near the Fermi energy. In the ballistic limit, when the distance to the Fermi level exceeds the inverse transport relaxation time $1/\tau$, we find the correction ...

Quantum transport at the Dirac point: Mapping out the minimum conductivity from pristine to disordered graphene [PDF]
, 2015 The phase space for graphene's minimum conductivity $\sigma_\mathrm{min}$ is mapped out using Landauer theory modified for scattering using Fermi's Golden Rule, as well as the Non-Equilibrium Green's Function (NEGF) simulation with a Monte Carlo sampling

Transition from diffusive to ballistic dynamics for a class of finite quantum models
, 2007 The transport of excitation probabilities amongst weakly coupled subunits is investigated for a class of finite quantum systems. It is demonstrated that the dynamical behavior of the transported quantity depends on the considered length scale, e. g., the
