Towards low-temperature peculiarities of thermodynamic quantities for decorated spin chains

چکیده
We discuss the origin of an enigmatic low-temperature behavior some one-dimensional decorated spin systems which was coined pseudo-transition. Tracing out parts results in standard Ising-chain model with temperature-dependent parameters and unexpected thermodynamic quantities correlations chains can be tracked down critical point at H=0 T=0. illustrate this perspective using as examples spin-1/2 Ising-XYZ diamond chain, coupled spin-electron double-tetrahedral Ising–Heisenberg chain.

Direct Calculation of Thermodynamic Quantities for
The XXX Heisenberg model is studied at finite temperature. The free energy is derived without recourse to Thermal Bethe Ansatz method and Quantum Transfer Matrix method. The result perfectly agrees with the free energy derived by Thermal Bethe Ansatz method. An explicit expression of the cluster expansion coefficient in arbitrary order is presented for the first time.
متن کاملFrom finite geometry exact quantities to (elliptic) scattering amplitudes for spin chains: the 1/2-XYZ
From finite geometry exact quantities to (elliptic) scattering amplitudes for spin chains: the 1/2-XYZ Abstract Initially, we derive a nonlinear integral equation for the vacuum counting function of the spin 1/2-XYZ chain in the disordered regime, thus paralleling similar results by Klümper [1], achieved through a different technique in the antiferro-electric regime. In terms of the counting fu...
متن کاملDerivation of thermodynamic quantities from kinetic measurements
Results are presented of both traditional equilibrium and also gas phase kinetic measurements. These results are used to show, — (1) that measured enthalpies of formation of the fluorosilanes are probably in error, (2) a 13—silicon substituted alkyl radical is stabilised by ca 12 kJ mol' and (3) the simplest divalent silicon species, SiR2, has an enthalpy of formation of 273 ± 6 kJ mo11, some 3...
متن کاملStatic thermodynamic quantities of quantum Heisenberg spin glasses with anisotropic interaction in applied magnetic fields.
In the static replica symmetric approximation, the quantum Heisenberg spin-glass model with the infinite-ranged random Dzyaloshinskii-Moriya interaction in external magnetic fields is investigated in detail. The local susceptibility and the corresponding order parameters are calculated, which are in good agreement with those of thermofield calculations. The dependencies of entropy and specific ...
متن کاملHaldane Gapped Spin Chains: Exact Low Temperature Expansions of Correlation Functions
We study both the static and dynamic properties of gapped, one-dimensional, Heisenberg, anti-ferromagnetic, spin chains at finite temperature through an analysis of the O(3) non-linear sigma model. Exploiting the integrability of this theory, we are able to compute an exact low temperature expansion of the finite temperature correlators. We do so using a truncated ‘form-factor’ expansion and so...
