Correlation Between Spin and Orbital Dynamics During Laser-Induced Femtosecond Demagnetization

Autor: Zhang, G. P., Gu, Mingqiang, Bai, Y. H., Jenkins, T. L., George, Thomas F.

Spin and orbital angular momenta are two intrinsic properties of an electron and are responsible for the physics of a solid. How the spin and orbital evolve with respect to each other on several hundred femtoseconds is largely unknown, but it is at t

Laser-induced ultrafast transport and demagnetization at the earliest time: First-principles and real-time investigation

Autor: Zhang, G. P., Bai, Y. H., Jenkins, T., George, T. F.

Here we carry out a first-principles time-dependent calculation to investigate how fast electrons actually move under laser excitation and how large the electron transport affects demagnetization on the shortest time scale. To take into account the t

Manifestation of intra-atomic 5d6s-4f exchange coupling in photoexcited gadolinium

Autor: Zhang, G. P., Jenkins, T., Bennett, M., Bai, Y. H.

Publikováno v: J. Phys.: Condens. Matter 29 (2017) 495807 (7pp)

Intra-atomic exchange couplings (IEC) between $5d6s$ and $4f$ electrons are ubiquitous in rare-earth metals and play a critical role in spin dynamics. However, detecting them in real time domain has been difficult. Here we show the direct evidence of

Dissertation/ Thesis

The contribution of brain reorganisation to recovery in patients with optic neuritis

Autor: Jenkins, T. M.

In this thesis, the mechanisms of damage and repair in clinically isolated optic neuritis (ON) were investigated in vivo, by combining magnetic resonance imaging (MRI), electrophysiology and optical coherence tomography (OCT). ON is a demyelinating,
