Description
Summary:Silver Degenerate States In article number 2204672, using high‐resolution transmission electron microscopy (HRTEM), Titus Masese, Godwill Mbiti Kanyolo, and co‐workers report novel honeycomb layered oxides exhibiting silveratom bilayers. The bilayers are theoretically understood via emergent SU(2) interactions with three distinct states of silver associated with fractional valency (sub‐valent) states, alongside conventional U(1) (electromagnetic) interaction. Breaking the SU(2)×U(1) symmetry, analogous to electroweak theory, generates silver mass terms manifesting as the bilayered structure.
