摘 要

Ion and atom traps had originally been
introduced with the aim of achieving high precision measurements but had then
evolved into devices for quantum computation and simulation. More recently
these goals have merged again today ion and atom traps offer a playground for
the precise exploration of effects from quantum field theory as well as
non-equilibrium statistical physics. In this lecture I will demonstrate that
it is possible in principle to verify the Unruh effect, ie the fact that an
accelerated observer in the vacuum is expected to see photons with trapped
atoms. Furthermore, I will show how the Kibble-Zurek mechanism which
describes the generation of defects upon traversal of a symmetry breaking
phase transition and may play a role in the formation of topological defects
in the early universe can be observed and verified accurately in an ion trap.
