Picosecond laser structuration under high pressures: observation of boron nitride nanorods
Luc Museur, Jean Pierre Petitet, Jean Pierre Michel +4
We report on picosecond UV-laser processing of hexagonal boron nitride (hBN) at moderately high pressures above 500 bar. The main effect is specific to the ambient gas and laser pu…
Transmission in the vicinity of the Dirac point in hexagonal Photonic Crystals
Marcus Diem, Thomas Koschny, C. M. Soukoulis
We use a scattering matrix approach to simulate the transmission through a hexagonal Photonic Crystal in the vicinity of the Dirac point. If the crystal is oriented so that the pro…
Strong diamagnetic response of metamaterials
E. N. Economou, Th. Koschny, C. M. Soukoulis
We demonstrate that there is a strong diamagnetic response of metamaterials, consisting of open or closed split ring resonators (SRRs). Detailed numerical work shows that for dense…
Observation of inter-Landau-level quantum coherence in semiconductor quantum wells
K. M. Dani, I. A. Cotoros, J. Wang +4
Using three-pulse four-wave-mixing femtosecond spectroscopy, we excite a non-radiative coherence between the discrete Landau levels of an undoped quantum well and study its dynamic…
Magnetization Relaxation and Collective Spin Excitations in Correlated Double--Exchange Ferromagnets
M. D. Kapetanakis, I. E. Perakis
We study spin relaxation and dynamics of collective spin excitations in correlated double--exchange ferromagnets. For this, we introduce an expansion of the Green's functions equat…
Spin dynamics in (III,Mn)V ferromagnetic semiconductors: the role of correlations
M. D. Kapetanakis, I. E. Perakis
We address the role of correlations between spin and charge degrees of freedom on the dynamical properties of ferromagnetic systems governed by the magnetic exchange interaction be…
