Simple holographic dual of the Maxwell-Cattaneo model & the fate of KMS symmetry for non-hydrodynamic modes
Yongjun Ahn, Matteo Baggioli, Yanyan Bu +2
Diffusion, as described by Fick's laws, governs the spreading of particles, information, data, and even financial fluctuations. However, due to its parabolic structure, the diffusi…
Holographic derivation of effective action for a dissipative neutral fluid
Yanyan Bu, Xiyang Sun
Using a holographic prescription for the Schwinger-Keldysh closed time path, we derive the effective action for a dissipative neutral fluid holographically described by the Einstei…
Chiral phase transition: effective field theory and holography
Yanyan Bu, Zexin Yang
We consider the chiral phase transition relevant for QCD matter at finite temperature but with vanishing baryon density. Presumably, the chiral phase transition is of second order…
Chiral Anomalous Magnetohydrodynamics in action: effective field theory and holography
Matteo Baggioli, Yanyan Bu, Xiyang Sun
Chiral Anomalous Magnetohydrodynamics (CAMHD) provides a low-energy effective framework for describing chiral fluids in the presence of dynamical electromagnetic fields and axial a…
