Energy Transmission Requires Information: Approaching the Physics of Boundary Interfaces

A research group, including Yuya Kusuki (Associate Professor, Institute for Advanced Study, Kyushu University / Visiting Scientist, iTHEMS), has demonstrated a clear inequality in 2-dimensional conformal quantum field theory. The inequality links the energy transmission rate, the information transmission rate, and an indicator of the size of the Hilbert space in quantum field theory (specifically, the growth rate of the number of states at high energy) as follows: (energy transmission rate) ≤ (information transmission rate) ≤ (indicator of the size of the Hilbert space).
