Curvature shapes chiral transport and entanglement in fermions
What the study found The study found that spacetime curvature in AdS2 and AdS2 black hole backgrounds can produce strongly asymmetric, or chiral, wave propagation for Dirac fermions. The authors report that this propagation is confined within an inhomogeneous Lieb-Robinson cone, a bound on how fast information spreads in a system. Why the authors say…
2D Abelian gauge theories show rich phase structure
What the study found Abelian gauge theories in 1+1 dimensions can have a surprisingly rich phase structure as masses are varied. The abstract says these systems include critical lines or points with central charge c = 1 and c = 1/2, and it also points to 2D chiral gauge theories as a setting for symmetric…
