Abstract Topological slow light exhibits potential to achieve stopped light by virtue of its widely known robust and non-reciprocal behaviours. Conventional approach for achieving topological slow light often involves flat-band engineering without disentangling the underlying physical mechanism. Here. we unveil the presence of counter-propagating waves within valley kink states as the... https://www.duospiritalis.com/top-deal-Serra-Avatar-Urza-s-Saga-clearance/
