Fulde-Ferrell-Larkin-Ovchinnikov superfluidity in one-dimensional optical lattices
M. Rizzi, Marco Polini, M. A. Cazalilla +3
Spin-polarized attractive Fermi gases in one-dimensional (1D) optical lattices are expected to be remarkably good candidates for the observation of the Fulde-Ferrell-Larkin-Ovchinn…
Direct resolution of unoccupied states in solids via two photon photoemission
W. Schattke, E. E. Krasovskii, R. Díez Muiño +1
Non-linear effects in photoemission are shown to open a new access to the band structure of unoccupied states in solids, totally different from hitherto used photoemission spectros…
Ultrafast Electron-Phonon Decoupling in Graphite
Kunie Ishioka, Muneaki Hase, Masahiro Kitajima +3
We report the ultrafast dynamics of the 47.4 THz coherent phonons of graphite interacting with a photoinduced non-equilibrium electron-hole plasma. Unlike conventional materials, u…
Systematic investigation of the structure of the Si(553)-Au surface from first principles
Sampsa Riikonen, Daniel Sanchez-Portal
We present here a comprehensive search for the structure of the Si(553)-Au reconstruction. More than two hundred different trial structures have been studied using first-principles…
Self-energy and lifetime of Shockley and image states on Cu(100) and Cu(111): Beyond the GW approximation of many-body theory
M. G. Vergniory, J. M. Pitarke, P. M. Echenique
We report many-body calculations of the self-energy and lifetime of Shockley and image states on the (100) and (111) surfaces of Cu that go beyond the approximation of many-bo…
Tunable Plasmon Molecules in Overlapping Nanovoids
I. Romero, T. V. Teperik, F. J. Garcia de Abajo
Coupled and shape-tailored metallic nanoparticles are known to exhibit hybridized plasmon resonances. This Letter discuss the optical properties of a complementary system formed by…
