Query: Light Dark Matter Search and Spectroscopy -- Brief Review and An
  Experimental Technique   A brief review of light dark matter particles and their spectroscopy is
presented, specifically aimed at understanding the interaction mechanisms of
axion and Axion-Like Particles (ALPs) with matter and an interim proposal and
some ideas for possible detection of these evasive particles. In order to
venture into the highly challenging spectral regions and extremely weak signals
involved with these searches (especially for the DFSZ axions), a different
scheme is proposed departing from the conventional resonant cavity mass scan
and heterodyne detection methods. We aim to look for a fixed mass axionic field
and concentrate our search at the corresponding resonant frequency and its
higher harmonics using a simple phase-sensitive dc detection method, which
could possibly be helpful in substantially reducing both the hardware,
experiment complexities and long run times. The probable mass range suggested
in the model presented here begins with 22.5microeV, corresponding to a
resonant frequency of 5.4GHz, going all the way to its two multiples of 90 and
112.5microeV (corresponding to 24.3 and 27.0GHz frequencies, respectively),
with high probability of finding an axion or ALP around these mass values. We
present a comprehensive measurement strategy and spectroscopy technique based
upon this model which revolves around a three-stage amplification and
phase-sensitive detection scheme to maximize and detect a resonant axionic
coupling to the U(1) fields under a coherent Primakoff effect interaction. The
feasibility of proposed scheme is demonstrated with some calculations,
simulations and preliminary tests. This experimental technique and ideas
reported here have significant potential to be developed into an extremely
sensitive narrow-range dark matter axion/ALP spectroscopy experiment.
