We calculate the decay of pionium atoms into two photons. The pion polariz-ability gives rise to a 10% correction to the corresponding decay width for pointlike pions. This opens the possibility to obtain the polarizability of the charged pion from a future measurement of this decay width if the ππ-scattering lengths are known to better than 5% precision. We also comment on the contribution of ...

Quasichemical theory is utilized to analyze the relative roles of solute polarization and size in determining the structure and thermodynamics of bulk anion hydration for the Hofmeister series Cl(-), Br(-), and I(-). Excellent agreement with experiment is obtained for whole salt hydration free energies using the polarizable AMOEBA force field. The total hydration free energies display a stronge...

We develop an analytical model for calculation of optical spectra metal nanostructures arbitrary shape supporting localized surface plasmons (LSPs). For plasmonic systems with characteristic size below the diffraction limit, we obtain explicit expression polarizability that describes lineshape solely in terms dielectric function and LSP frequency. The amplitude spectral band is determined by ef...
