Comparison between Causal and Acausal Diffusion: a Schwinger-Keldysh Effective Field Theory Perspective
Navid Abbasi, Matthias Kaminski, Dirk H. Rischke
In Fick's time-honored theory of diffusion, the system responds instantaneously to external perturbations, resulting in acausal behavior. Maxwell-Cattaneo theory addresses this iss…

Pole-skipping as order parameter to probe a quantum critical point
Navid Abbasi, Karl Landsteiner
The holographic system described by Einstein-Maxwell-Chern-Simons dynamics in the bulk of AdS exhibits a chiral magnetic effect and a quantum critical point. Through numerical calc…

Long-time tails in the SYK chain from the effective field theory with a large number of derivatives
Navid Abbasi
We study the nonlinear energy diffusion through the SYK chain in the framework of Schwinger-Keldysh effective field theory. We analytically construct the interacting effective Lagr…
