Optomagnetic forces on YIG/YFeO3 microspheres levitated in chiral hollow-core photonic crystal fibre
Soumya Chakraborty, Gordon K. L. Wong, Ferdi Oda +9
We explore a magnetooptomechanical system consisting of a single magnetic microparticle optically levitated within the core of a helically twisted single-ring hollow-core photonic…

Improving electron tomography of mesoporous silica by Ga intrusion
Alexander Kichigin, Johannes Böhmer, Moritz Buwen +11
Electron tomography (ET) offers nanoscale 3D characterization of mesoporous materials but is often limited by their low scattering contrast. Here, we introduce a gallium (Ga) intru…
