Thesis title:


Dynamical interplay of light and superconductivity at
nanoscale


Description
:
Superconductivity is a macroscopic quantum effect with a

variety of
fascinating properties.

As reflected in its name, one of those is the dissipation less flow of
electrical current


a

feature very much appreciated for desired energy savings.
Nevertheless, the superconducting

state is highly sensitive to a
variety of external factors,
such as temperature, the magnetic

field, or exposure to light


i.e. bombardment of
relatively high energetic photons, to name a

few. Although the latter effect is useful to
construct superconductor
-
based single photon

detector
s, the underlying physics is not fully
understood.

The aim of this
thesis

is to expand

our knowledge about the nontrivial interplay

of
superconductivity and light.
The incentive for these new hybrid structures is given by
recent breakthroughs achieved in the

field of plasmonics, in which the interplay of light
with nanostructured metallic materials is

investigated

[1]
.

Within this th
esis we will create a

completely
new type of hybrid systems

combining

a thin

superconducting film with such a nanostructured metallic film
. These structures will be
investigated using, low temperature, transport measurements.
