Atom inside of hollow nanofiber
|
Profile of an atomic beam propagating through a dielectric cylinder of radius R = 50 nm and length l = 1 μm
Density of atoms in the cross section of the beam at distance z = 0 μm and (d) z = 6 μm |
We
investigate the van der
Waals interaction of an atom with the internal surface of a metal or
dielectric
nanometer-sized cylinder and derive analytical equations for the van
der Waals
surface potential and force in the electrostatic approximation. We show
that
for a concave cylindrical surface the van der Waals potential energy
can be up
to four times larger than for a flat surface. This result is
qualitatively
explained by a reduction in the effective distance between the atom and
the
concave surface compared to that for a flat surface. We also evaluate
the shape
of an atomic beam propagating inside a hollow dielectric
submicrometer-sized
cylinder and we propose a scheme that will enable a precise measurement
of the
van der Waals constant C3 References: |
