New Atomic probes for Dark Matter detection: Axions, Axion-like
  particles and Topological Defects
  We present a brief overview of recently proposed detection schemes for axion,
axion-like pseudoscalar particle and topological defect dark matter. We focus
mainly on the possibility of using atomic and molecular systems for dark matter
detection. For axions and axion-like particles, these methods are complementary
probes to ongoing photon-axion interconversion experiments and astrophysical
observations. For topological defects, these methods are complementary to
conventional astrophysical search schemes based on gravitational signatures.
