Shear subdiffusion in non-relativistic holography
Yan Liu, Zhi-Ling Wang, Xin-Meng Wu
We study shear fluctuations in non-relativistic holographic systems coupled to torsional Newton-Cartan geometry, using asymptotically Lifshitz spacetimes in Einstein-Maxwell-dilato…

Holographic Schwinger-Keldysh effective field theories including a non-hydrodynamic mode
Yan Liu, Ya-Wen Sun, Xin-Meng Wu
We derive the Schwinger-Keldysh effective field theories for diffusion including the lowest non-hydrodynamic degree of freedom from holographic Gubser-Rocha systems. At low tempera…
