Probing confined fields with single molecules and vice versa.
Single dye molecules are used as local probes to map the spatial distribution of the squared electric field components in the focus of a high numerical aperture lens. Simulated field distributions are quantitatively verified by experimentally obtained fluorescence excitation maps. We show that annular illumination can be used to engineer the field distribution in the focus at a dielectric/air i...
متن کاملProbing Composite Fermions with a Wigner Crystal and Vice-Versa
Two-dimensional electron gases in high magnetic fields have proven to be a remarkably rich playground for the study of strongly-correlated quantum many-body systems. In two dimensions with a strong magnetic field, the cyclotron motion of the electrons completely quenches the particle kinetic energy into Landau levels which are macroscopically degenerate–the number of states in a Landau level is...
متن کاملMaximal monotone operators are selfdual vector fields and vice-versa
If L is a selfdual Lagrangian L on a reflexive phase space X ×X∗, then the vector field x → ∂̄L(x) := {p ∈ X∗; (p, x) ∈ ∂L(x, p)} is maximal monotone. Conversely, any maximal monotone operator T on X is derived from such a potential on phase space, that is there exists a selfdual Lagrangian L on X ×X∗ (i.e, L∗(p, x) = L(x, p)) such that T = ∂̄L. This solution to problems raised by Fitzpatrick can...
متن کاملStructure in Melody, and vice versa
In this paper we argue for a slightly modified conception of phonological representations along the lines of Government Phonology. Releasing C and V from their traditional, phonetically oriented connotations as consonants and vowels and promoting them into abstract phonological primitives, we show that phonological elements, melodic expressions and phonological structure can be viewed in a unfi...
متن کاملFrom numbers to Numerals and Vice Versa
Universally used decimal representations, such as 5; 200; 856763; 189200000 are rendered (written, pronounced) differently in different languages. The number 5 is tllus five in English, fern in Swedish, cinq in French, ketsmala in Koyukon, biyar in Hausa and nga: in Burmese. Numbers can furthermore be written differently in different mathematical systems. The number 5 is written V in the Roman ...
