#### Manipulation of single electron spin in a GaAs quantum dot through the application of geometric phases: The Feynman disentangling technique

(2010-12-31)

The spin of a single electron in an electrically defined quantum dot in a two-dimensional electron gas can be manipulated by moving the quantum dot adiabatically in a closed loop in the two-dimensional plane under the ...

#### Coarse-graining RNA nanostructures for molecular dynamics simulations

(2010-12-31)

A series of coarse-grained models have been developed for study of the molecular dynamics of RNA nanostructures. The models in the series have one to three beads per nucleotide and include different amounts of detailed ...

#### Spin-orbit interaction in three-dimensionally bounded semiconductor nanostructures

(2010-12-31)

The structural inversion asymmetry-induced spin-orbit interaction of conduction band electrons in zinc-blende and wurtzite semiconductor structures is analysed allowing for a three-dimensional (3D) character of the external ...

#### Numerical analysis of complex systems evolution with phase transformations at different spatial scales

(2010-12-31)

This paper shows the existence of a critical dimension for finite length nanowires exhibiting shape memory effects. We give a brief survey of phase transformations, their classifications, and provide the basis of mathematical ...

#### Complex systems in finance: Monte Carlo evaluation of first passage time density functions

(2010-12-31)

Many examples of complex systems are provided by applications in finance and economics areas. Some of intrinsic features of such systems lie with the fact that their parts are interacting in a non-trivial dynamic manner ...

#### Band structures of laterally coupled quantum dots, accounting for electromechanical effects

(2010-12-31)

In a series of recent papers we demonstrated that coupled electro-mechanical effects can lead to pronounced contributions in band structure calculations of low dimensional semiconductor nanostructures (LDSNs) such as quantum ...

#### Microstructures of constrained shape memory alloy nanowires under thermal effects

(2010-12-31)

In this paper, martensitic transformations in constrained Fe-Pd nanowires are studied using a mesoscopic model analyzed in detail numerically in our earlier papers. The dynamics of squareto-rectangular transformation is ...

#### Higher-order nonlinear electromechanical effects in wurtzite GaN/AlN quantum dots

(2010-12-31)

As we demonstrated earlier, conventional mathematical models based on linear approximations may be inadequate in the analysis of properties of low-dimensional nanostructures and band structure calculations. In this work, ...

#### Influence of electromechanical effects and wetting layers on band structures of AlN/GaN quantum dots and spin control

(2010-12-31)

In a series of recent papers we demonstrated that coupled electromechanical effects can lead to pronounced contributions in band structure calculations of low dimensional semiconductor nanostructures (LDSNs) such as quantum ...

#### Geometry and temperature dependent thermal conductivity of diamond nanowires: A non-equilibrium molecular dynamics study

(2010-12-31)

Using non-equilibrium molecular dynamics methods, the analysis of geometry and temperature dependent thermal conductivities of diamond nanowires is carried out. It is found that at the same temperature conditions, thermal ...
