Confined optical phonon modes in polar tetrapod nanocrystals detected by resonant inelastic light scattering
R. Krahne, G. Chilla, C. Schueller +6
We investigated CdTe nanocrystal tetrapods of different sizes by resonant inelastic light scattering at room temperature and under cryogenic conditions. We observe a strongly reson…
NNLO Logarithmic Expansions and Exact Solutions of the DGLAP Equations from x-Space: New Algorithms for Precision Studies at the LHC
Alessandro Cafarella, Claudio Coriano', Marco Guzzi
A NNLO analysis of certain logarithmic expansions, developed for precision studies of the evolution of the QCD parton distributions (pdf) at the Large Hadron Collider, is presented…
Double Transverse-Spin Asymmetries in Drell-Yan Processes with Antiprotons
Vincenzo Barone, Alessandro Cafarella, Claudio Coriano' +2
We present next-to-leading order predictions for double transverse-spin asymmetries in Drell--Yan dilepton production initiated by proton--antiproton scattering. The kinematic regi…
On the models of nonlocal nonlinear optics
Boris G. Konopelchenko, Antonio Moro
We show that under certain assumptions a general model of nonlocal nonlinear response in 1+1-dimension is equivalent to the model considered by Krolikowski and Bang for a Kerr-type…
Density Matrix Renormalization Group Study of the Disorder Line in the Quantum ANNNI Model
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
We apply Density Matrix Renormalization Group methods to study the phase diagram of the quantum ANNNI model in the region of low frustration where the ferromagnetic coupling is lar…
On the extended resolvent of the Nonstationary Schrodingher operator for a Darboux transformed potential
M. Boiti, F. Pempinelli, A. K. Pogrebkov
In the framework of the resolvent approach it is introduced a so called twisting operator that is able, at the same time, to superimpose à la Darboux solitons to a generic smoo…
