چکیده

The coupling between phonon and magnon is ubiquitous in magnetic materials plays a crucial role many aspects of properties, most notably spintronics. Yet, this academically technologically interesting problem still poses severe challenge to general understanding the issue certain materials. We report that Ni3TeO6 exhibits clear evidence significant magnon-phonon both longitudinal thermal conductivity ($\kappa_{xx}$) Hall coefficient ($\kappa_{xy}$). Debye-Callaway model, phenomenological description for heat conduction, can explain measured field dependence $\kappa_{xx}(H)$: scattering from spin fluctuation paramagnetic phase additional due collinear antiferromagnetic phase. further suggest similar approach could be applied understand finite $\kappa_{xy}$ values $Ni_3TeO_6$.

Diagonal Dominance and Harmless Off-diagonal Delays

Systems of linear differential equations with constant coefficients, as well as Lotka–Volterra equations, with delays in the off–diagonal terms are considered. Such systems are shown to be asymptotically stable for any choice of delays if and only if the matrix has a negative weakly dominant diagonal.

Off - Diagonal

Experience shows that there is a strong parallel between metrization theory for compact spaces and for linearly ordered spaces in terms of diagonal conditions. Recent theorems of Gruenhage, Pelant, Kombarov, and Stepanova have described metrizability of compact (and related) spaces in terms of the offdiagonal behavior of those spaces, i.e., in terms of properties of X −∆. In this paper, we show...

An improved variational approach to off-diagonal exciton-phonon coupling.

A state-of-the-art variational wave function incorporating Jastrow-type exciton-phonon correlations, the global-local Ansatz, is utilized to elucidate exciton-phonon correlations in a generalized form of the Holstein Hamiltonian with the simultaneous presence of diagonal and off-diagonal exciton-phonon coupling. Much lowered ground-state energies are found for the global-local Ansatz when compa...

Resonant energy transfer assisted by off-diagonal coupling.

Dynamics of resonant energy transfer of a single excitation in a molecular dimer system are studied in the simultaneous presence of diagonal and off-diagonal exciton-phonon coupling. It is found that, at given temperatures, the off-diagonal coupling can enhance both the coherence of the resonant energy transfer and the net quantity of energy transferred from an initially excited monomer to the ...

Off-diagonal geometric phases.

We investigate the adiabatic evolution of a set of nondegenerate eigenstates of a parametrized Hamiltonian. Their relative phase change can be related to geometric measurable quantities that extend the familiar concept of Berry phase to the evolution of more than one state. We present several physical systems where these concepts can be applied, including an experiment on microwave cavities for...
