Ground-state properties of a supersymmetric fermion chain
Ground-state properties supersymmetric fermion chain
2010/12/27
We analyze the ground state of a strongly interacting fermion chain with a supersymmetry. We conjecture a number of exact results, such as a hidden duality between weak and strong couplings. By explo...
Cladding mode coupling in highly localized fiber Bragg gratings: modal properties and transmission spectra
Cladding mode fiber Bragg gratings modal properties transmission spectra
2010/11/16
The spectral characteristics of a fiber Bragg grating (FBG) with a transversely inhomogeneous refractive index profile, differs con- siderably from that of a transversely uniform one. Transmission sp...
Impact of intrinsic localized modes of atomic motion on materials properties

Recent neutron and x-ray scattering measurements show intrinsic localized modes (ILMs) in metallic uranium and ionic sodium iodide. Here, the role ILMs play in the behavior of these materials is exami...
Magnetic fluids may be classified as ferrofluids (FF), which are colloidal suspensions of very fine (» 10 nm) magnetic particles, and magnetorheological fluids, which are suspensions of larger, ...
Study of the Structure and Some Physical Properties of Sodium-Boro-Phosphate Glasses Containing Antimony and Iron Oxides
Glass structure Physical properties of glass Glass containing antimony and iron oxides
2010/4/13
Boro-phosphate glasses containing transition metal oxides are of special interest. Hence, some sodium-Boro-phosphate glasses containing iron and antimony oxides were prepared and investigated. The str...
