Temperature corrections to conformal field theory

We consider finite temperature dynamical correlation functions in the interacting delta-function Bose gas. In the low-temperature limit the asymptotic behaviour of correlation functions can be determined from conformal field theory. In the present work we determine the deviations from conformal behaviour at low temperatures. Received: 14 January 1998 / Accepted: 17 March 1998     

Synthesis and aminomethylation of some heterocyclic α-nitroxyalkyl NH acids

The recently discovered synthetic route to quaternary ammonium salts of a new series via N-aminometylation of 4,4-bis(nitroxymethyl)oxazolidin-2-one was extended to other NH acids obtained for the first time by O-nitration of known a-hydroxyalkyl derivatives of 4-methyloxazolidin-2-one, pyrrolidin-2-one, and benzimidazole. In the aminomethylation of these NH acids, dimethylamine and morpholine were used as the amine components.
