Emission of fast energetic nucleons in intermediate energy nuclear collisions is investigated in the framework of two specific non-equilibrium models. In the lower energy region considered, the Fermi Jet mechanism dominates whereas results in the higher energy region are suggestive of emission from a hot dense source formed inside cold nuclear matter.

Molecular dynamics and DSMC models for energy transfer in argon dimer argon monomer collisions are compared. The inelastic collision number for these collisions is evaluated, and found to decrease significantly when gas temperature increases.

Electron transport is computed in 3nm Si nanowires subject to incoherent scattering from phonons. The electronic structure of the nanowire is represented in an atomistic sp3d5s* tight binding basis. Phonon modes are computed in an atomistic valence force field rather than a continuum deformation potential. Atomistic transport and incoherent scattering are coupled through the non-equilibrium Gre...

Electron transport through a system of two quantum dots connected in series is studied theoretically with the use of non-equilibrium Green function formalism based on the equation of motion method. Each dot is described by the one-level Anderson Hamiltonian and interdot Coulomb interactions in the form of the Hubbard-like term are taken into account. The electric current and occupation numbers ...

In this paper, the study of the recombination of non-equilibrium charge carriers and determination of recombination mechanisms in Ge/Si heterostructures with nanoislands have been presented. The effects of long-term photoconductivity decay in Ge/Si heterostructures with Ge nanoislands have been found as caused by variations of the electrostatic potential in the near-surface region of Si(100) su...

We study electronic transport in quantum-dot structures made of graphene. Focusing on the rectangular dot geometry and utilizing the non-equilibrium Green's function to calculate the transmission in the tight-binding framework, we find significant fluctuations in the transmission as a function of the electron energy. The fluctuations are correlated with the formation of quantum scarring states,...

To obtain the physical quantities of interest within the non-equilibrium Green’s function formalism, numerical integration over energy space is essential. Several adaptive methods have been implemented and tested for their applicability. The number of energy grid points needed and the convergence behavior of the SchrödingerPoisson iteration have been evaluated. An adaptive algorithm based on a ...

From the non-equilibrium critical relaxation study of the two-dimensional Ising model, the dynamical critical exponent z is estimated to be 2.165 ± 0.010 for this model. The relaxation in the ordered phase of this model is consistent with exp(− √ t/τ ) behavior. The interface energy of the threedimensional Ising model is studied and the critical exponent of the correlation length ν and the crit...

Metallic nanostructures under optical illumination can generate a non-equilibrium high-energy electron gas (also known as hot electrons) capable of being injected into neighbouring media over a potential barrier at particle boundaries. The nature of this process is highly nanoparticle shape and size dependent. Here, we have derived an analytical expression for the frequency dependent rate of in...
