Selective Probing of Hidden Spin-Polarized States in Inversion-Symmetric Bulk MoS_{2}.
Spin- and angle-resolved photoemission spectroscopy is used to reveal that a large spin polarization is observable in the bulk centrosymmetric transition metal dichalcogenide MoS_{2}. It is found that the measured spin polarization can be reversed by changing the handedness of incident circularly polarized light. Calculations based on a three-step model of photoemission show that the valley and...

The ARPES experiments were performed at the Advanced Resonant Spectroscopies (ADRESS) beamline at the Swiss Light Source (SLS). Data were collected using circularly-polarized light with an overall energy resolution of 50-80 meV. The samples were cleaved in situ at about 25 K and measured in a vacuum always better than 5× 10−11 mbar. The experimental geometry is described in Ref. [1]. Figure 1 (...

متن کاملSymmetric curvature tensor
Recently, we have used the symmetric bracket of vector fields, and developed the notion of the symmetric derivation. Using this machinery, we have defined the concept of symmetric curvature. This concept is natural and is related to the notions divergence and Laplacian of vector fields. This concept is also related to the derivations on the algebra of symmetric forms which has been discu...
