A Green's-function approach to nonlinear electronic transport in a static electric field is developed microscopically for the system composed of interacting electrons with impurities and phonons. The essential idea separate center-of-mass motion from relative electrons. An electron temperature introduced as measurement internal energy without reference any distribution function. By allowing different temperatures decoupled phonons initial state, we obtain density matrix electron-lattice...
The nonlinear transport for interacting electrons with phonons and impurities is studied in the presence of a strong electric field $E$. By separating center-of-mass motion from relative we are able to obtain force- energy-balance equations steady states, which electron temperature current density can be determined self-consistently as function
Landslide monitoring and early warning systems are the most successful countermeasures to reduce fatalities economic losses from landslide hazards. The traditional strategies such as GPS extensometers relatively expensive difficult be installed in steep, high mountains. In this study, a MEMS (Micro Electro Mechanical Systems) based multivariate wireless sensor unit was used build system for rainfall-triggered landslides, one of practical cost-effective hard-reached multi-source its...

Abstract The dislocation dynamics in Fe-based alloys are significantly different at high temperatures compared to room temperature. Due the influence of solid solution atom segregation crystal, walls can easily form, leading fine grain strengthening. This mechanism makes study highly valuable for practical applications. To explore Cr-Mo and under small strain conditions, correlation between aggregation was investigated using molecular (MD) method. Under same strain, most affected by solute...
Abstract Large rock avalanches are ubiquitous surface hazards on Earth and characterized by long runout distances high velocities. These extreme mobility features regarded as the key causes of catastrophic damage. Commonly, these a complicated set geological settings behaviors. Although many hypotheses have been proposed to explain this phenomenon, comprehensive explanation its is lacking. To precisely identify mechanisms large avalanches, we examined data collected from deposit Nyixoi...
The balance-equation approach to nonlinear hot-carrier transport theory, formulated by Lei and Ting (1984), is addressed in this comprehensive review. A central feature the role of strong electron-electron interactions promoting rapid thermalization about drifted state concomitant substantial simplification theory. This physical embodied initial density matrix chosen represent unperturbed carrier system. Force energy balance equations are for dc steady state, ac dynamic transient cases...
We present a quantum Boltzmann equation analysis of the spin-Hall effect in diffusive Rashba two-dimensional electron system. Within framework self-consistent Born approximation, we consider roles disorder-induced quasiclassical relaxation, collisional broadening quasiparticles, and intracollisional field regard to dynamics. an analytical proof that current vanishes, independently coupling strength, quasiparticle broadening, temperature, specific form isotropic scattering potential. A sum...
We propose a simple scheme for implementing quantum logic gates with string of two-level trapped cold ions outside the Lamb-Dicke limit. Two internal states each ion are used as one computational qubit (CQ) and collective vibration acts information bus, i.e., bus (BQ). Using dynamics laser-ion interaction described by generalized Jaynes-Cummings model, we show that entanglement between any CQ BQ can be coherently manipulated applying classical laser beams. As result, universal gates,...
Summary Damage induced by microcracking affects not only the mechanical behaviour of geomaterials but also their hydraulic properties. Evaluating these impacts is important for many engineering applications, such as safety assessment radioactive waste disposal facilities. This paper presents a new constitutive model accounting simultaneously impact damage on and properties unsaturated poroplastic geomaterials. The hydro‐mechanical coupling formulated means thermodynamic framework partially...
