Anisotropic ultrafast electron dynamics induced by high-field terahertz pulses in n-doped InGaAs
Anisotropic ultrafast electron dynamics high-field terahertz pulses
2010/11/23
The anisotropic effective mass of electrons is directly measured using time-resolved THz-
pump/THz-probe techniques in a n-doped InGaAs semiconductor thin film. A microscopic theory
is used to attri...

Momentum-Resolved Ultrafast Electron Dynamics Bi2Sr2CaCu2O8+delta
2010/11/18
The non-equilibrium state of the high-Tc superconductor Bi2Sr2CaCu2O8+ and its ultrafast dynamics have been investigated by femtosecond time- and angle-resolved photoemission spectroscopy well below ...
Width dependent collisionless electron dynamics in the static fields of the shock ramp,2,Phase space portrait
Width dependent collisionless electron dynamics static fields shock ramp Phase space portrait
2009/11/13
We study numerically in detail the behaviour of electrons in the strongly inhomogeneous static magnetic and electric fields, which are typical for thin quasiperpendicular collisionless shocks. We pay ...
Width dependent collisionless electron dynamics in the static fields of the shock ramp,1,Single particle behavior and implications for downstream distribution
Width dependent collisionless electron dynamics static fields shock ramp
2009/11/13
We study the collisionless dynamics of electrons in the shock ramp using the numerical trajectory analysis in the model electric and magnetic fields of the shock. Even with very modest assumptions abo...
Monopole and Topological Electron Dynamics in Adiabatic Spintronic and Graphene Systems
Monopole and Topological Electron Dynamics Adiabatic Spintronic Graphene Systems

A unified theoretical treatment is presented to describe the physics of electron dynamics in semiconductor and graphene systems. Electron spin fast alignment with the Zeeman magnetic field (physical o...
DC Electric Field Effects on the Electron Dynamics in Double Rectangular Quantum Dots
Coupled quantum dots DC bias Coherence Relaxation
2010/9/25
The effect of a dc electric field on the temporal evolution of an electron in a double rectangular quantum dot is explored in this work. In the framework of the effective mass approximation, first-ord...
