Strictly linear light cones in long-range interacting systems of arbitrary dimensions

T Kuwahara, K Saito - Physical Review X, 2020 - APS
In locally interacting quantum many-body systems, the velocity of information propagation is
finitely bounded, and a linear light cone can be defined. Outside the light cone, the amount …

Nearly linear light cones in long-range interacting quantum systems

M Foss-Feig, ZX Gong, CW Clark, AV Gorshkov - Physical review letters, 2015 - APS
In nonrelativistic quantum theories with short-range Hamiltonians, a velocity v can be
