Bose-einstein Condensation of Magnons
We use the Renormalization Group method to study the Bose-Einstein condensation of the interacting dilute magnons which appears in three dimensional spin systems in magnetic field. The obtained temperature dependence of the critical field Hc(T) – Hc(0) ~ T 2 is different from the recent self-consistent Hartree-FockPopov calculations (cond-matt 0405422) in which a T 3/2 dependence was reported. ...
متن کاملBose-Einstein condensation of magnons in TlCuCl3
A quantitative study of the field-induced magnetic ordering in TlCuCl3 in terms of a Bose-Einstein condensation (BEC) of magnons is presented. It is shown that the hitherto proposed simple BEC scenario is in quantitative and qualitative disagreement with experiment. It is further shown that even very small Dzyaloshinsky-Moriya interactions or a staggered g tensor component of a certain type can...
متن کاملBose-Einstein Condensation of Confined Magnons in Nanostructures
A number of diverse kinds of magnetic experiments are shown to lead to the observation of a Bose-Einstein condensation of magnons in some nanostructures, especially in Fe and in Co/Pt. The experiments include 1) the measurement of magnetic aftereffect, 2) measurements of Néel’s fluctuation field, including an estimate of activation volume, 3) the measurement of the energy gap which provides a l...
متن کاملBose-Einstein condensation of magnons under incoherent pumping.
Bose-Einstein condensation in a gas of magnons pumped by an incoherent pumping source is experimentally studied at room temperature. We demonstrate that the condensation can be achieved in a gas of bosons under conditions of incoherent pumping. The critical transition point is shown to be almost independent of the frequency spectrum of the pumping source and is solely determined by the density ...
متن کاملProbing anomalous longitudinal fluctuations of the interacting Bose gas via Bose-Einstein condensation of magnons.
The emergence of a finite staggered magnetization in quantum Heisenberg antiferromagnets subject to a uniform magnetic field can be viewed as Bose-Einstein condensation of magnons. Using nonperturbative results for the infrared behavior of the interacting Bose gas, we present exact results for the staggered spin-spin correlation functions of quantum antiferromagnets in a magnetic field at zero ...
