Strictly linear light cones in long-range interacting systems of arbitrary dimensions
Tomotaka Kuwahara, Keiji Saito
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 am…

Area law of non-critical ground states in 1D long-range interacting systems
Tomotaka Kuwahara, Keiji Saito
The area law for entanglement provides one of the most important connections between information theory and quantum many-body physics. It is not only related to the universality of…

Coherence cost for violating conservation laws
Hiroyasu Tajima, Naoto Shiraishi, Keiji Saito
Nature imposes many restrictions on the operations that we perform. Many of these restrictions can be interpreted in terms of {\it resource} required to realize the operations. Cla…
