Dramatic enhancement of intrinsic two-photon absorption in a conjugated porphyrin dimer by Karotki, A, Drobizhev, M, Dzenis, Y, Taylor, P, Anderson, H, Rebane, A

“…We report strong cooperative enhancement of simultaneous two-photon absorption cross section in a porphyrin dimer. The two-photon cross section, σ 2 = 6 × 10 -47 cm 4s/photon, corresponds to a 400-fold increase over the value measured for the monomer, and is one of the largest ever obtained for organic chromophore of similar size.…”

Transmission of low-energy scalar waves through a traversable wormhole by Bahareh Azad, Farhang Loran, Ali Mostafazadeh

“…We provide a comprehensive treatment of this problem offering analytic expressions for the transmission and reflection amplitudes of the corresponding effective potential and the absorption cross section of the wormhole. Our results, which are based on a recently developed dynamical formulation of time-independent scattering theory, apply to a large class of wormhole spacetimes including a wormhole with a sharp transition, the Ellis wormhole, and a family of its generalizations.…”
