Spatial Equalization of Zero Dispersion Wavelength Profiles in Nonlinear Fibers

Longitudinal zero-dispersion wavelength (ZDW) fluctuations in long waveguides impose a fundamental limit on the achievable parametric mixer bandwidth. We demonstrate for the first time that the precisely measured ZDW profile can be taken advantage of by ap ...

NMR Shifts for Polycyclic Aromatic Hydrocarbons From First-Principles

Nicola Marzari

We present first-principles, density-functional theory calculations of the NMR chemical shifts for polycyclic aromatic hydrocarbons, starting with benzene and increasing sizes up to the one- and two-dimensional infinite limits of graphene ribbons and sheet ...

Large time decay and scattering for Wave Maps

Joachim Krieger

Let u : R3+1 -> H-2 be a Wave Map with smooth compactly supported initial data satisfying the smallness condition parallel to u[0]parallel to ((H) over dot3/2 x (H) over dot1/2) < epsilon for a sufficiently small epsilon > 0. In particular, the Wave Map ex ...

Search for B+→D*+π0 decay

Olivier Schneider, Aurelio Bay, Mingkui Wang, Chao Wang, Tagir Aushev, Vladislav Balagura, Jean Wicht, Xiao Wang

We report on a search for the doubly Cabibbo suppressed decay B+→D*+π0, based on a data sample of 657×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find no significant signal and set ...

Singularly perturbed piecewise deterministic games

Alain Haurie

In this paper we consider a class of hybrid stochastic games with the piecewise open-loop information structure. These games are indexed over a parameter

First-principles study of Fe and FeAl defects in SiGe alloys

Alexandra Sarabando de Carvalho

First-principles, spin-polarized local-density-functional calculations are used to model interstitial iron (Fei) and its complexes with substitutional aluminum in dilute SixGe1−x alloys (x

Magnetic excitations near the quantum phase transition in the Ising ferromagnet LiHoF4

Henrik Moodysson Rønnow, Conradin Kraemer

Effective-medium theory and inelastic neutron scattering are used to study the magnetic excitations in the Ising ferromagnet LiHoF4 near its magnetic-field-induced quantum phase transition (QPT). As expected, the dominant mode softens at the QPT, but reach ...

Eikonal approximation in Ads/CFT: from shock waves to four-point functions

We initiate a program to generalize the standard eikonal approximation to compute amplitudes in Anti-de Sitter spacetimes. Inspired by the shock wave derivation of the eikonal amplitude in flat space, we study the two-point function epsilon similar to < O1 ...

On the Long-Run Behavior of Equation-Based Rate Control

Jean-Yves Le Boudec, Milan Vojnovic

AbstractWe consider unicast equation-based rate con-trol, where, at some points in time, a sender adjusts its rate to f(p,r), where p is an on-line estimate of the loss-event rate observed by this source, r of the average round-trip time, and f is a TCP th ...

Supercritical reaction calorimetry: A novel route to supercritical fluid reaction monitoring

Thierry Meyer, Charalampos Mantelis, Frédéric Lavanchy

Supercrit. fluids (SCFs) were intensively studied in the last decade as alternative, environment-friendly benign reaction solvents. A new anal. technique was derived from a combination of classical heat flow reaction calorimetry and the supercrit. fluid te ...
