Decay at infinity of caloric functions within characteristic hyperplanes

L. Escauriaza, C. E. Kenig, G. Ponce +1

It is shown that a function $u$ satisfying, $∣Δ u + \partial_{t} u ∣ \leq M (∣ u ∣ + ∣\nabla u ∣)$ , $∣ u (x, t) ∣ \leq M e^{M ∣ x ∣^{2}}$ in $R^{n} \times [0, T]$ and $∣ u (x, 0) ∣ \leq C_{k} e^{- k ∣ x ∣^{2}}$ in $R^{n}$ and…

Electron-hole and plasmon excitations in 3d transition metals: Ab initio calculations and inelastic x-ray scattering measurements

I. G. Gurtubay, J. M. Pitarke, Wei Ku +5

We report extensive all-electron time-dependent density-functional calculations and nonresonant inelastic x-ray scattering measurements of the dynamical structure factor of 3d tran…

Neutron scattering investigations on methyl group dynamics in polymers

Juan Colmenero, Angel J. Moreno, Angel Alegria

Among the different dynamical processes that take place in polymers, methyl group rotation is perhaps the simplest one, since all the relevant interactions on the methyl group can…

Non-formal compact manifolds with small Betti numbers

Marisa Fernandez, Vicente Muñoz

We show that, for any $k \geq 1$ , there exist non-formal compact orientable $(k - 1)$ -connected $n$ -manifolds with $k$ -th Betti number $b_{k} = b \geq 0$ if and only if $n\geq \max \{4k-1,…

Induced Charge-Density Oscillations at Metal Surfaces

V. M. Silkin, I. A. Nechaev, E. V. Chulkov +1

Induced charge-density (ICD) oscillations at the Cu(111) surface caused by an external impurity are studied within linear response theory. The calculation takes into account such p…

Quantum optical time-of-arrival model in three dimensions

V. Hannstein, G. C. Hegerfeldt, J. G. Muga

We investigate the three-dimensional formulation of a recently proposed operational arrival-time model. It is shown that within typical conditions for optical transitions the resul…
