Explore the innovative concept of Pulsar Polarization Array (PPA) in this comprehensive lecture from the ICBS2024 conference. Delve into the dual nature of pulsars as astronomical clocks and linear polarizers, and discover how these characteristics are harnessed to form galaxy-scale interferometers. Learn about the Pulsar Timing Array (PTA) methodology developed in the 1980s for detecting nano-Hertz gravitational waves, and understand how the newly proposed PPA utilizes readily available polarization data to investigate novel phenomena in astrophysics and fundamental physics. Examine the PPA's unique ability to reveal temporal and spatial correlations at large scales, distinguishing them from local noise. Gain insights into the PPA's potential for detecting ultralight axion-like wave dark matter, and consider the possibilities of synergizing PPA and PTA methodologies for enhanced scientific exploration. This hour-long talk provides a thorough introduction to this cutting-edge astronomical technique and its implications for our understanding of the universe.
