Today, our new paper on four-dimensional conserved topological charge vectors in plasmonic quasicrystals appeared in Science:

Four-dimensional cube (so-called tesseract) on a gold surface with five-fold symmetry. The quasi-crystalline two-dimensional plasmon pattern can be recognized under the tesseract. The image represents the projection of a four-dimensional regular cube onto a quasi-crystalline two-dimensional plane.
