We show that it has a phonino pole and at low frequencies there is a depletion of spectral weight with a power-law scaling which is governed by a locally quantum critical point.

WebSPECTRAL THEORY OF A STRING I. S. Kats UDC 517.9 In this survey, we present the principal results of Krein's spectral theory of a string and describe its de- velopment by … Web4. The spectral function in physics tells you the probability that a particle with a certain momentum k has a specific energy ω. In other words, due to the Heisenberg uncertainty relation, a particle can have an energy that is distributed around a mean. The spectral function A ( k, ω) describes exactly this distribution.
