Griffiths effects and slow dynamics in nearly many-body localized systems
Griffiths effects and slow dynamics in nearly many-body localized systems
The low-frequency response of systems near a many-body localization transition can be dominated by rare regions that are locally critical or "in the other phase". It is known that, in one dimension, these rare regions can cause the d.c. conductivity and diffusion constant to vanish even inside the delocalized thermal …
