Title: Stark effect tunable terahertz transitions in finite carbon chains
Title: 有限碳链中的斯塔克效应可调太赫兹跃迁
Abstract: We employ a tight-binding model to calculate the optical selection rules of gold-terminated carbyne chains in the presence of an applied electric field. We show that both the magnitude of the edge-state gap and the strength of optical transitions across it can be tuned via the Stark effect. In the case of sufficiently long carbyne chains, the dipole transitions between edge states occur within the THz frequency range.
