Interaction Region Lattice for Fcc-ee (tlep)

FCC-ee (TLEP) project is high-luminosity ee collider and is an essential part of the Future Circular Collider (FCC) design study at CERN [1–3]. FCC-ee is being designed to reach center-of-mass energy from 90 to 350 GeV with circumference of 80-100 km to study Higgs boson properties and perform precise measurements at the electroweak scale. It is also an intermediate step towards 100 TeV proton-...

Lattice dynamics and electron-phonon interaction in (3,3) carbon nanotubes.

We present a detailed study of the lattice dynamics and electron-phonon coupling for a (3,3) carbon nanotube which belongs to the class of small diameter based nanotubes which have recently been claimed to be superconducting. We treat the electronic and phononic degrees of freedom completely by modern ab initio methods without involving approximations beyond the local density approximation. Usi...

Lattice dynamics of solid C60.

The lattice dynamics of C60 has been studied first by means of group theory and then by diagonalizing the dynamical matrix for two recently proposed intermolecular potentials. The libron and phonon energies are calculated as a function of momentum along various symmetry directions with and without phonon–libron interactions. The effects of these interactions on the density of states are also di...

Electronic Structure of Conjugated Polymers: Consequences of Electron}lattice Coupling

Conjugated organic polymers can be doped, via oxidation or reduction chemistry or via acid}base chemistry, to induce very high electrical conductivity. Conjugated polymers are beginning to "nd uses, in both the neutral and the doped states, in prototype molecular-based electronics applications and in electronic and opto-electronic devices. The physical basis for the many of the unusual properti...
