Casimir force between a sphere and a plane: spectral representation formalism
Cecilia Noguez, C. E. Roman-Velazquez
We develop a spectral representation formalism to calculate the Casimir force in the non-retarded limit, between a spherical particle and a substrate, both with arbitrary local die…
High-multipolar effects on the Casimir force: the non-retarded limit
Cecilia Noguez, Carlos E. Roman-Velazquez, Raul Esquivel-Sirvent +1
We calculate exactly the Casimir force or dispersive force, in the non-retarded limit, between a spherical nanoparticle and a substrate beyond the London's or dipolar approximation…
Electronic and optical properties of InAs(110)
X. Lopez-Lozano, Cecilia Noguez, L. Meza-Montes
The electronic and optical properties of the cleavage InAs(110) surface are studied using a semi-empirical tight-binding method which employs an extended atomic-like basis set. We…
High-Multipolar Effects on Dispersive Forces
Cecilia Noguez, Carlos E. Roman-Velazquez, R. Esquivel-Sirvent +1
We show that the dispersive force between a spherical nanoparticle (with a radius 100 nm) and a substrate is enhanced by several orders of magnitude when the sphere is near t…
Circular dichroism simulated spectra of chiral gold nanoclusters: A dipole approximation
Carlos E. Roman-Velazquez, Cecilia Noguez, Ignacio L. garzon
Circular dichroism (CD) spectra of chiral bare and thiol-passivated gold nanoclusters have been calculated within the dipole approximation. The calculated CD spectra show features…
Atomic structure and electronic properties of the cleavage InAs(110) surface
X. Lopez-Lozano, Cecilia Noguez, L. Meza-Montes
The electronic properties of the cleavage InAs(110) surface are studied using a semi-empirical tight-binding method which employs an extended atomic-like basis set. We calculate th…
