Web29 jun. 2024 · The study of topological insulators (TIs) originated with electronic states in condensed matter physics ( 1 – 4 ), and they were later studied in electromagnetic materials ( 5 – 8 ). Recently, TIs have been investigated for phononic systems (elastic waves in solids) to control statical floppy modes ( 9 – 15) and dynamical edge waves ( 16, 17 ).

The time periods in this table are measured by considering λ = 1, n = 99, ħ = 1, ω = 100, B = 1, C = ± 1 (surface/bulk), θ = π 4 and v = 1. Parameters are considered in the units of λ − 1. TI … Web19 sep. 2014 · Abstract In the presence of a circularly polarized mid-infrared radiation graphene develops dynamical band gaps in its quasienergy band structure and becomes a Floquet insulator. Here, we analyze how topologically protected edge states arise inside these gaps in the presence of an edge.
