Angle-resolved photoemission from molecules in the independent-atomic-center approximation

Coral Snake Mimicry: Does It Occur?

“…Another persistent and inappropriate objection to the mimicry hypothesis is that front-fanged coral snakes are nocturnal and, therefore, not subject to attack by diurnal predators with color vision (5,5,(25)(26)(27). Observations on various North {28), Central {11, 26,29), and South American {30-32) species show that these snakes often are active during daylight.…”

“…Grobman (27) mentioned several objections to aposematism in venomous coral snakes (81), and proposed that resemblance to these animals by other snakes be known as pseudomimicry. We agree that two species might resemble each other as a result of some factor or factors other than predator deception (25,42,43).…”

“…This criterion has been used to argue both for (5,41) and against (25,27) coral snake mimicry. The ambiguity is caused by the likelihood of multiple functions for brightly ringed patterns, including background matching, protean effects, and prey location (25,42,43); the possibility that migratory predators are involved (44); and the possibility that allopatry among some possible models and mimics is a comparatively recent phenomenon (5,45).…”

Configuration-specific electronic structure of strongly interacting interfaces: TiOPc on Cu(110)

“…This is, however, unlikely, because the STM data show that prior to SA "O-down" molecules adsorbed on terraces are tilted only by a rather small amount. Selection rules and photoemission cross section are thus expected to be similar for both configurations prior to SA [48].…”

Efficient and accurate modeling of electron photoemission in nanostructures with TDDFT

“…Besides the TDSE, Floquet theory [32,33], the strong-field approximation [34,35] and semi-classical methods [36,37,38,39] based on ionization rates [40] are used in the strong-field regime. For weak lasers, plane wave methods [41], the independent atomic center approximation [42] and (multiphoton) perturbation theory [43,44,45] are usually employed. However, such approaches reproduce dynamics only qualitatively, and their failure to describe multielectron (correlation) effects and their often oversimplified assumptions for the continuum state call for better schemes.…”
