Abstract
Periodic driving of systems of particles can create crystalline structures in
time. Such systems can be used to study solid-state physics phenomena in the
time domain. In addition, it is possible to engineer the wave-number band
structure of optical systems and to realize photonic time crystals by periodic
temporal modulation of the material properties of the electromagnetic wave
propagation medium. We introduce here a versatile averaged-permittivity
approach which empowers emulating various condensed matter phases in the time
dimension in a traveling wave resonator. This is achieved by utilizing temporal
modulation of permittivity within a small segment of the resonator and the
spatial shape of the segment. The required frequency and depth of the
modulation are experimentally achievable, opening a pathway for research into
the practical realisation of crystalline structures in time utilising microwave
and optical systems.
