We study the plaquette valence bond solid phase in an XXZ-type spin-1/2 model in the kagome lattice. The low-energy theory for this phase is a U(1) lattice gauge theory on the honeycomb lattice. We find that there is an emergent 1-form U(1) symmetry at low energy and there is a mixed anomaly.

Graphical Abstract Framework nucleic acids (FNAs)-based peptide vaccines with different structures and sizes were constructed to understand the effect of peptide spacing and carrier rigidity on B cell activation, and reveal the significance of precise peptide organization. Epitopes from SARS-CoV-2 were assembled on the preferred FNA to construct a COVID-19 peptide vaccine prototype which effectively triggered humoral immune responses in mice.
