Properties of entanglement in a Spin Chain with impurities
(2012-11-09)
In this thesis we have studied the e®ects on ground-state entanglement and
quantum-state transfer caused by the presence of one and two diagonal impu-
rities in a 1D ring-shaped spin-1
2 hamiltonian with XX ferromagnetic ...
Diffusion and implantation of dopants in single-wall carbon nanotubes:a spectroscopic investigation of chemical and electronic properties
(2012-11-09)
Raman measurements, performed on MWCNTs grown by arc discharge
method in He atmosphere, have pointed out the occurrence of a band at 1780-
1860 cm–1, regardless of the use of a catalytic Ni-Cr alloy in the synthesis ...
