Characteristic temperatures of a triplon system of dimerized quantum magnets
(World Scientific Publishing Co. Pte. Ltd., 2021)Exploiting the analogy between ultracold atomic gases and the system of triplons, we study magneto-thermodynamic properties of dimerized quantum magnets in the framework of Bose–Einstein condensation (BEC). Particularly, ... -
Effects of exchange and weak Dzyaloshinsky–Moriya anisotropies on thermodynamic characteristics of spin-gapped magnets
(World Scientific Publishing Co. Pte. Ltd., 2021-10-08)We study the modification of low-temperature properties of quantum magnets such as magnetization, heat capacity, energy spectrum and densities of condensed and noncondensed quasiparticles (triplons) due to anisotropies in ... -
Joule-Thomson temperature of a triplon system of dimerized quantum magnets
(Elsevier, 2020)It is well known that, for a system of atomic (molecular) gases both kinds of processes, isentropic as well as isenthalpic are realizable and widely used in refrigeration technique. Particularly, magnetic refrigeration ... -
Spin-gapped magnets with weak anisotropies I: Constraints on the phase of the condensate wave function
(Elsevier, 2020-11-27)We study the thermodynamic properties of dimerized spin-gapped quantum magnets with and without exchange anisotropy (EA) and Dzyaloshinsky and Moriya (DM) anisotropies within the mean-field approximation (MFA). For this ...
