Effective field theory of particle mixing
Shuyang Cao, Daniel Boyanovsky
We introduce an effective field theory to study \emph{indirect} mixing of two fields induced by their couplings to a common decay channel in a medium. The extension of the method o…

Chern Simons condensate from misaligned axions
Shuyang Cao, Daniel Boyanovsky
We obtain the non-equilibrium condensate of the Chern Simons density induced by a misaligned homogeneous coherent axion field in linear response. The Chern-Simons dynamical suscept…

Dynamics of axion-neutral pseudoscalar mixing
Shuyang Cao, Wenjie Huang, Daniel Boyanovsky
Axions mix with neutral pions after the QCD phase transition through their common coupling to the radiation bath via a Chern-Simons term, as a consequence of the anomaly. Th…
