ANALOGOUS HAWKING EFFECT: S-MATRIX AND THERMOFIELD DYNAMICS

Analogous Hawking Effect: S-Matrix and Thermofield Dynamics

We consider the full S-matrix in the scattering giving rise to analogous Hawking radiation in dispersive media.We show the general structure of the scattering in the weak dispersion approximation and discuss some unnoticed features of the primary process, with a possible generalization of the phenomenology of the Hawking effect.In particular, we st

Field-scale water balance closure in seasonally frozen conditions

Hydrological water balance closure is a simple concept, yet in practice it is uncommon to measure every significant term independently in the field.Here we demonstrate the degree to which the field-scale water balance can be closed using only routine field observations in a seasonally frozen prairie pasture field site in Saskatchewan, Canada.Arrays
