Surface magnetoinductive breathers in two-dimensional magnetic metamaterials
Maria Eleftheriou, Nikos Lazarides, George P. Tsironis +1
We study discrete surface breathers in two-dimensional lattices of inductively-coupled split-ring resonators with capacitive nonlinearity. We consider both Hamiltonian and dissipat…
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…
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…
Softening of ultra-nanocrystalline diamond at low grain sizes
Ioannis N. Remediakis, Georgios Kopidakis, Pantelis C. Kelires
Ultra-nanocrystalline diamond is a polycrystalline material, having crystalline diamond grains of sizes in the nanometer regime. We study the structure and mechanical properties of…
Memory Effect in the Photoinduced Femtosecond Rotation of Magnetization in the Ferromagnetic Semiconductor GaMnAs
J. Wang, I. Cotoros, X. Liu +4
We report a femtosecond response in photoinduced magnetization rotation in the ferromagnetic semiconductor GaMnAs, which allows for detection of a four-state magnetic memory at the…
Structure, elastic properties and strength of amorphous and nanocomposite carbon
Ioannis N. Remediakis, Maria G. Fyta, Christos Mathioudakis +2
We study theoretically the equilibrium structure, as well as the response under external load, of characteristic carbon-based materials. The materials considered include diamond, a…
