Schwinger-Keldysh effective field theory of type-B Goldstone: near-diagonal geometry and Berry term
Pei Zheng, Mei Huang
In this work, we formulate a finite temperature Schwinger-Keldysh effective field theory for type-B Goldstone modes. In particular, we organize the required two time contour struct…

Dynamical instability and transport peak of chiral matter from holography
Pei Zheng, Yidian Chen, Danning Li +2
We study dynamical properties of strongly coupled chiral matter by using holographic method. We demonstrate, at both linear and nonlinear levels, that perturbations on thermodynami…

Non-equilibrium dynamics of Goldstone excitation from holography
Pei Zheng, Yidian Chen, Danning Li +2
By using the holographic approach, we investigate the interplay between the order parameter and Goldstone modes in the real-time dynamics of the chiral phase transition. By quenchi…
