Mott insulators in the strong spin-orbit coupling limit: from Heisenberg to a quantum compass and Kitaev models. [PDF]

Physical Review Letters, 2008
We study the magnetic interactions in Mott-Hubbard systems with partially filled t_{2g} levels and with strong spin-orbit coupling. The latter entangles the spin and orbital spaces, and leads to a rich variety of the low energy Hamiltonians that ...

Room temperature magnetization switching in topological insulator-ferromagnet heterostructures by spin-orbit torques [PDF]

Nature Communications, 2017
Topological insulators with spin-momentum-locked topological surface states are expected to exhibit a giant spin-orbit torque in the topological insulator/ferromagnet systems.

Visualizing the invisible: inner plexiform layer stratification with conventional spectral-domain optical coherence tomography

International Journal of Retina and Vitreous
Background The inner plexiform layer (IPL) of the retina plays a key role in visual processing, consisting of five stratified sub-bands (S1-S5) that segregate ON and OFF visual pathways.

Congenital upper eyelids ectropion in Down’s syndrome

GMS Ophthalmology Cases, 2017
Congenital bilateral ectropion of the upper eyelids is a rare, benign condition reported in ophthalmic literature. It is more frequently associated with Down’s syndrome, ichthyosis, and sporadic cases in newborns from black population.

Gigantic intrinsic orbital Hall effects in weakly spin-orbit coupled metals [PDF]

Physical review B, 2018
A recent paper [D. Go et al., Phys. Rev. Lett. 121, 086602 (2018)] proposed that the intrinsic orbital Hall effect (OHE) can emerge from momentum-space orbital texture in centrosymmetric materials.
