A Note on Colored Tornheim's Double Series
In this short note, we provide an explicit formula to compute every colored
double Tornheim's series by using double polylogarithm values at roots of
unity. When the colors are given by our formula is different from that
of Tsumura [On alternating analogues of Tornheim's double series II, Ramanujan
J. 18 (2009), 81-90] even though numerical data confirm both are correct in
almost all the cases. This agreement can also be checked rigorously by using
regularized double shuffle relations of the alternating double zeta values in
weights less than eight.Comment: 2 page
Vibronic effects on electronic spectra and nonadiabatic photophysics. A quantum/classical dynamical approach.
Quantum vibronic effects have a remarkable impact on the lineshape of electronic spectra.1 They can also play an important role in the dynamics of photophysical processes like internal conversions at Conical Intersections or charge and energy transfer in multichromophoric systems.
Recent advancements allow a fair description of such effects in rigid (harmonic) molecules in gas phase.1-4 However, in biology and in material science the photoexcited chomophores are usually embedded in a solvent, possibly establishing with them specific interactions, or even in more complex and heterogeneous environments. Moreover, many systems with interesting optical properties are flexible, i.e. the optical transition triggers large-amplitude curvilinear distortions, and this challenges the applicability of harmonic approximation. Trajectory based approaches are very suitable to deal with these scenarios but they neglect quantum nuclear effects.
We are currently working with the hope to devise robust hybrid quantum/classical (QC) approaches to merge the potentialities of trajectory based methods and those of the quantum vibronic methods developed for rigid systems in gas phase or implicit solvents.1,5-6 The system is partitioned in two subsystems: a quantum core (the chromophore or just its high-frequency modes) and an environment (which can include also large amplitude motions of the system itself and is treated at a more approximate classical level) and the challenge is the reliable description of their mutual couplings. We will illustrate our recent results with a number of examples ranging from the chiro-otpical properties of flexible conjugated systems (e.g. oligothiophenes) to the nonadiabatic decay of photoexcited DNA nucleobases7 in acqueous solution. 8-12

An exotic shuffle relation of and
In this short note we will provide a new and shorter proof of the following
exotic shuffle relation of multiple zeta values:
\zeta(\{2\}^m \sha\{3,1\}^n)={2n+m\choose m}
\frac{\pi^{4n+2m}}{(2n+1)\cdot (4n+2m+1)!}. This was proved by Zagier when
n=0, by Broadhurst when , and by Borwein, Bradley, and Broadhurst when
m=1. In general this was proved by Bowman and Bradley in \emph{The algebra and
combinatorics of shuffles and multiple zeta values}, J. of Combinatorial
Theory, Series A, Vol. \textbf{97} (1)(2002), 43--63. Our idea in the general
case is to use the method of Borwein et al. to reduce the above general
relation to some families of combinatorial identities which can be verified by
WZ-method.Comment: 5 page

The Galactic Bar
We summarize recent work on the structure and dynamics of the Galactic bar
and inner disk. Current work focusses on constructing a quantitative model
which integrates NIR photometry, source count observations, gas kinematics,
stellar dynamical observations, and microlensing. Some avenues for future
research are discussed.Comment: 7 pages, LaTeX, 4 figures. To appear in the Proceedings of Joint
