Rashba effect in quantum networks [PDF]

, 2005
We present a formalism to study quantum networks made up by single-channel quantum wires in the presence of Rashba spin-orbit coupling and magnetic field. In particular, linear transport through one-dimensional and two-dimensional finite-size networks is

Dynamic Exchange Coupling in Magnetic Bilayers [PDF]

Physical Review Letters, 2003
A long-ranged dynamic interaction between ferromagnetic films separated by normal-metal spacers is reported, which is communicated by nonequilibrium spin currents. It is measured by ferromagnetic resonance (FMR) and explained by an adiabatic spin-pump theory. In FMR the spin-pump mechanism of spatially separated magnetic moments leads to an appreciable

Spin-relaxation anisotropy in a nanowire quantum dot with strong spin-orbit coupling

, 2018
We study the impacts of the magnetic field direction on the spin-manipulation and the spin-relaxation in a one-dimensional quantum dot with strong spin-orbit coupling.

Dynamical Magnetoelectric Coupling in Helical Magnets [PDF]

Physical Review Letters, 2007
Collective mode dynamics of the helical magnets coupled to electric polarization via spin-orbit interaction is studied theoretically. The soft modes associated with the ferroelectricity are not the transverse optical phonons, as expected from the Lyddane-Sachs-Teller relation, but are the spin waves hybridized with the electric polarization. This leads

Cavity optomagnonics with magnetic textures: coupling a magnetic vortex to light

, 2018
Optomagnonic systems, where light couples coherently to collective excitations in magnetically ordered solids, are currently of high interest due to their potential for quantum information processing platforms at the nanoscale.

Can slow roll inflation induce relevant helical magnetic fields?

, 2011
We study the generation of helical magnetic fields during single field inflation induced by an axial coupling of the electromagnetic field to the inflaton. During slow roll inflation, we find that such a coupling always leads to a blue spectrum with $B^2(

Interfacial Rashba magnetoresistance of two-dimensional electron gas at LaAlO$_3$/SrTiO$_3$ interface

, 2017
We report the angular dependence of magnetoresistance in two-dimensional electron gas at LaAlO$_3$/SrTiO$_3$ interface. We find that this interfacial magnetoresistance exhibits a similar angular dependence to the spin Hall magnetoresistance observed in ...

Magnetization dynamics in magnetically coupled heterostructures [PDF]

, 2009
This thesis focusses on the influence of interlayer coupling on the magnetization dynamics of heterostructure systems. This topic has been investigated by time-resolved photoemission electron microscopy (PEEM) using a pump-probe approach. Magnetic and chemical contrast is provided by the llumination with circularly polarized x-rays due to the x-ray ...

Development and Application of a Gyro Steady-State Drilling Tool

Shiyou jixie, 2023
Due to the formation heterogeneity,unsteady pump rate,high weight on bit and fast rotation,drill strings are associated with multiple kinds of vibration.Severe vibration accelerates the bit failure,increases the tripping operations,and thus impacts the ...

Coupled magnetic plasmons in metamaterials

, 2009
Magnetic metamaterials consist of magnetic resonators smaller in size than their excitation wavelengths. Their unique electromagnetic properties were characterized by the effective media theory at the early stage.
