  We investigate the interplay between chirality and confinement induced by the
presence of an external potential. For potentials having radial symmetry, the
circular character of the trajectories induced by the chiral motion reduces the
spatial fluctuations of the particle, thus providing an extra effective
confining mechanism, that can be interpreted as a lowering of the effective
temperature. In the case of non-radial potentials, for instance, with an
elliptic shape, chirality displays a richer scenario. Indeed, the chirality can
break the parity symmetry of the potential that is always fullfilled in the
non-chiral system. The probability distribution displays a strong
non-Maxwell-Boltzmann shape that emerges in cross-correlations between the two
Cartesian components of the position, that vanishes in the absence of chirality
or when radial symmetry of the potential is restored. These results are
obtained by considering two popular models in active matter, i.e. chiral Active
Brownian particles and chiral active Ornstein-Uhlenbeck particles.
