  Chiral active matter is enjoying a rapid increase of interest, spurred by the
rich variety of asymmetries that can be attained in e.g. the shape or
self-propulsion mechanism of active particles. Though this has already led to
the observance of so-called chiral crystals, active chiral glasses remain
largely unexplored. A possible reason for this could be the naive expectation
that interactions dominate the glassy dynamics and the details of the active
motion become increasingly less relevant. Here we show that quite the opposite
is true by studying the glassy dynamics of interacting chiral active Brownian
particles (cABPs). We demonstrate that when our chiral fluid is pushed to
glassy conditions, it exhibits highly nontrivial dynamics, especially compared
to a standard linear active fluid such as common ABPs. Despite the added
complexity, we are still able to present a full rationalization for all
identified dynamical regimes. Most notably, we introduce a new 'hammering'
mechanism, unique to rapidly spinning particles in high-density conditions,
that can fluidize a chiral active solid.
