  • We present some partial results on the general infrared behaviour of bulk critical 1D quantum systems with a boundary. We investigate whether the boundary entropy, s(T ), is always bounded below as the temperature T decreases towards 0, and whether the boundary always becomes critical in the infrared limit. We show that failure of these properties is equivalent to certain seemingly pathological behaviours far from the boundary. One of our approaches uses real time methods, in which locality at… CONTINUE READING
