The specific heat of the slightly distorted {Mo72V30} with D5h symmetry leads to a drastic decrease of the singlet contribution, which is consistent with the partial lifting of the frustration and the decrease of degenerated low-energy states. The singlet excitation existence is confirmed further by the temperature dependence of the ESR spectra. Magnetic susceptibility and spin dynamics of a polyoxovanadate cluster.

Here we consider the spin axis dynamics of Kepler-62f and Kepler-186f, both of which reside in the habitable zone around their host stars. Using N-body simulations and secular numerical integrations, we describe their obliquity evolution for particular realizations of the planetary systems....

EPR Theories for Selection Rules to Observe the Spin Gap.

Determining Ts in the whole BCS-BEC crossover region, we identify the spin-gap regime in the phase diagram of a Fermi gas in terms of the temperature and the strength of a pairing interaction. We also clarify how the spin-gap phenomenon is related to the pseudogap phenomenon appearing in the single-particle density of states.

Local spin susceptibility of the $S=\\frac{1}{2}$ kagome.

Even though the cluster is not rhombus-shaped, results for the $N=45$ cluster could contribute for our understanding of the system because the cluster is larger than the $N=36$ cluster. Results for the $N=45$ cluster have partly been presented in Ref. 13 , which reported the results for a region of large m down to a height of $m\sim 1/2$.

Singlet Ground State and Spin Gap in S=1/2 Kagome.

Abstract Numerical diagonalization methods are employed to study spin-1/2 spherical kagome clusters realized in W 72 V 30 and Mo 72 V 30 , where the former is expected to have the ideal symmetry I h and the latter is a little distorted. For the ideal model with I h symmetry we calculate spin correlation functions in the ground state, which resemble the spin-1/2 kagome antiferomagnet closely. We provide strong numerical evidence, using improved variational wave functions, for a ground state with vanishing spin gap in the spin-$1/2$ quantum Heisenberg model on the kagome lattice.

It had been believed that Mo 72 V 30 could be described by the I h model, and a quantum Monte Carlo calculation of the magnetic susceptibility was performed in order to. Apr 10, 2008 · From magnetic susceptibility and high-field magnetization measurements, it was found that the ground state is a disordered singlet with the spin gap, as predicted from a recent theory. Exact diagonalization for a 12-site Kagomé cluster was performed to analyze the magnetic susceptibility, and individual exchange interactions were evaluated. In general, there are four ways to execute a spin-off: Regular spin-off - Completed all at once in a 100% distribution to shareholders. Majority spin-off - Parent retains a minority interest (< 20%) in SpinCo and distributes the majority of the SpinCo stock to shareholders. Equity carve out (IPO) / spin-off - Implemented as a second step.

Mar 03, 2008 · From magnetic susceptibility and high-field magnetization measurements, it was found that the ground state is a disordered singlet with the spin gap, as predicted from a recent theory. Exact diagonalization for a 12-site Kagome cluster was performed to analyze the magnetic susceptibility, and individual exchange interactions were evaluated. Sep 09, 2005 · The syntheses and magnetic susceptibilities of a pure series of rare copper minerals from the atacamite family with general formula ZnxCu4-x(OH)6Cl2 (0 ≤ x ≤ 1) are reported. The structure of these compounds features a corner-sharing triangular kagomé lattice of antiferromagnetically coupled Cu(II) ions. We correlate the onset of magnetic ordering with the mole fraction of paramagnetic Cu. For the spin-12 Heisenberg antiferromagnet on the Kagomé lattice we calculate the high temperature series for the specific heat and the structure factor. A comparison of the series with exact diagonalisation studies shows that the specific heat has further structure at lower temperature in addition to a high temperature peak at T≈2/3. At T=0.25 the structure factor agrees quite well with.
