The most successful effective theory describing fermions at finite density is Landau's Fermi liquid theory. The theory is basically a free fixed point under the renormalization group flow toward the Fermi surface. The experimental observation of...

Current techniques cannot detect axion dark matter over much of its parameter space, particularly in the theoretically well-motivated region where the axion decay constant f_a lies near the GUT and Planck scales. We suggest a novel experimental...
