Weak coupling of pseudoacoustic phonons and magnon dynamics in the incommensurate spin-ladder compound Sr14Cu24O41

Phys. Rev. B 94, 134309 (2016) - Published 21 October, 2016

Incommensurate compounds consist of two or more interpenetrating sublattices with lattice periods incommensurate along one or more crystal axes. Intriguing lattice dynamics have been predicted for these compounds and are relevant to not only the thermal properties but also electronic, optical, and magnetic properties via coupling between different energy excitations. Here, the authors report inelastic neutron scattering measurements of phonon and magnon dispersions in Sr14Cu24O41, which contains incommensurate chain and ladder substructures. Two distinct acoustic phononlike modes, corresponding to the sliding motion of one sublattice against the other, are observed for atomic motions polarized along the incommensurate axis. In the long-wavelength limit, it is found that the sliding mode shows a remarkably small energy gap, indicating very weak interactions between the two incommensurate sublattices. The measurements also reveal an appreciable contribution from gapped magnons to the low-temperature specific heat, as well as a gapped and steep linear magnon dispersion of the ladders. The high group velocity of this magnon branch and weak coupling with acoustic phonons can explain the large magnon thermal conductivity in Sr14Cu24O41 crystals. These findings offer new insights into the phonon and magnon dynamics and thermal transport properties of incommensurate magnetic crystals that contain low-dimensional substructures.

Finding and proving the exact ground state of a generalized Ising model by convex optimization and MAX-SAT

Lattice models are widely used to represent the statistical mechanics of condensed phases for the study of alloy thermodynamics, phase transitions, magnetic properties, fluid mechanics, and other applications. A longstanding problem has been the identification of the true global ground states of a lattice model, which is challenging for general models, and only a limited number of solutions for highly simplified systems are known. Here, a practical and general algorithm is presented that allows to determine provable periodically constrained ground states of complex lattice models up to a given unit cell size and in most cases is able to prove global optimality over all possible choices of unit cells. This universal algorithm is developed by reformulating the ground-state problem in terms of maximum satisfiability (MAX-SAT) and convex optimization, which results in both provable accuracy and sufficient numerical efficiency to handle systems of physically relevant complexity. Considering that lattice-model ground states are conventionally solved using simulated annealing or genetic algorithms, techniques that are often unable to find the true global minimum and provide no handle to prove the optimality of their results, this work promises to resolve the longstanding uncertainties in lattice models of important physical phenomena.

Determining the spin-orbit coupling via spin-polarized spectroscopy of magnetic impurities

V. Kaladzhyan, P. Simon, and C. Bena

Phys. Rev. B 94, 134511 (2016) - Published 12 October, 2016

The well known spin-orbit coupling is a peculiar type of interaction that links the direction of electron motion to its intrinsic magnetic moment, called spin. The role of the spin orbit is believed to be particularly important in giving rise to exotic states of matter, such as topological insulators and topological superconductors, that could host, for example, Majorana fermions. Despite several methods of measuring the spin-orbit constant having already been developed, given the rapid progress in the discovery and possible applications of new materials with strong spin-orbit coupling, it is important to provide experimentalists with novel and general approaches to unequivocally measure the value of this coupling. Here, the authors show theoretically that the spin-orbit coupling in two-dimensional and one-dimensional systems, both superconducting and metallic, can be read off directly and unambiguously via spin-resolved scanning tunneling microscopy (STM). The authors analyze the Friedel oscillations in the local density of state occurring due to scattering by localized magnetic impurities. In particular, they focus on the Fourier transform (FT) of the Friedel oscillations and note that the FT features observed in non-spin-polarized measurements split when using spin-polarized STM, and the splitting is exactly equal to twice the inverse spin-orbit length. Moreover, the superconducting systems exhibit extra high-intensity FT features with respect to the metallic systems, at a wavevector given by twice the inverse spin-orbit length. Such features provide a direct measure of the spin-orbit coupling in these materials.
