These results are confirmed by the experimental reconstruction of all 3D optical vortex lattices. It is shown that the optical vortices are created and annihilated during light propagation behind the mask with the preservation of the total topological charge. The 3D optical vortex lattices are ...
Ultracold fermions in optical lattices2,3 provide a clean and well-controlled platform offering a path to simulate the FHM. Doping the antiferromagnetic ground state of a FHM simulator at half-filling is expected to yield various exotic phases, including stripe order4, pseudogap5, and d-wave ...
The magnetic switching within these simple systems was measured using a novel dark-field magneto-optical Kerr effect magnetometry technique. This methodology is very exciting but has not been applied to the manufacture of complex 3D nanostructured lattices. Finally, two-photon lithography and ...

fabricated nanolattices using IP-Dip photoresist, followed by pyrolysis at 900 °C36. These pyrolytic carbon structures achieved densities below 1.0 g/cm3 and GPa-level strengths, indicating excellent lightweight and robust properties. In these thermolysis studies, the base of the structure is...
This opens a promising route towards downscaling photonic lattices and the creation of mechanically robust glass-ceramic microstructures. Keywords: direct laser writing; ultrafast laser; 3D laser lithography; 3D printing; hybrid polymer; integrated micro-optics; optical damage; photonics; pyrolysis; ...
Driven vortex lattices have been studied in Nb films, in which natural random pinning coexists with artificial ordered arrays of defects (submicrometric Ni dots). Three different dynamic regimes are found: for low vortex velocities, there is a plastic flow regime in which random defects frustrate...

The core of the vortex in the Néel order parameter for an easy-plane antiferromagnet on a honeycomb lattice is demonstrated to bind two zero-energy states. Remarkably, a single electron occupying this midgap band has its spin fragmented between the two sublattices: Whereas it yields a vanishing...
