Precision is a virtue in science in general and nanotechnology in particular
where carefully fabricated nanometer-scale devices hold great promise in both
classical and quantum regimes. Ground-state cooling or phonon amplification
require, for example, a sideband resolved photon-phonon coupling where
unavoidable imperfections often impose severe performance limits. However,
imperfection and disorder are ubiquitous in Nature and emerge with a role
particularly important in nanoscale devices.
In this talk, I will explore the limits imposed by imperfection in different
nanodevices, but not only. In certain cases, disorder may be invoked to enable
new functionalities and can be exploited to enhance the light-matter
interaction in different fields of nanotechnology such as quantum photonics
[1], nonlinear photonics [2], phononics [2] and optomechanics [3].
