Spin-orbit torque in 3D topological insulator-ferromagnet heterostructure: crossover between bulk and surface transport
Sumit Ghosh, Aurelien Manchon
Current-driven spin-orbit torques are investigated in a heterostructure composed of a ferromagnet deposited on top of a three dimensional topological insulator using the linear res…

Optical levitation of 10 nanogram spheres with nano- acceleration sensitivity
Fernando Monteiro, Sumita Ghosh, Adam Getzels Fine +1
We demonstrate optical levitation of SiO spheres with masses ranging from 0.1 to 30 nanograms. In high vacuum, we observe that the measured acceleration sensitivity improves fo…
