Photoinduced dynamics of nematic order parameter in FeSe

T. Konstantinova, L. Wu, M. Abeykoon, R. J. Koch, A. F. Wang, R. K. Li, X. Shen, J. Li, J. Tao, I. A. Zaliznyak, C. Petrovic, S. J. L. Billinge, X. J. Wang, E. S. Bozin, and Y. Zhu

Phys. Rev. B 99, 180102(R) (2019) - Published 28 May, 2019

Nematicity is deemed a precursor of superconductivity in unconventional superconductors. Here, the authors investigate the formation of a nematic phase and the dynamics of nematic fluctuations in FeSe using ultrafast electron diffraction. They find an enhancement of the high-symmetry crystalline order as a result of photoinduced suppression of low-symmetry local lattice distortion. This distortion, which is a signature of nematic fluctuations, is corroborated by x-ray pair distribution function analysis and electron microscopy, and is present in a wide temperature range below and above the nematic phase transition.

Ultrafast quantum-path interferometry revealing the generation process of coherent phonons

Kazutaka G. Nakamura, Kensuke Yokota, Yuki Okuda, Rintaro Kase, Takashi Kitashima, Yu Mishima, Yutaka Shikano, and Yosuke Kayanuma

Phys. Rev. B 99, 180301(R) (2019) - Published 20 May, 2019

Ultrafast quantum-path interferometry by using a pair of relative-phase-locked femtosecond pulses is proposed to evaluate the contribution of each quantum path in an optical transition. The observed characteristic interference fringes (collapse and revival) reveal that the impulsive stimulated Raman scattering is dominant in the coherent-phonon generation in n-type GaAs even in an opaque condition. It is demonstrated that the optical dual-pulse pumping actively creates quantum mechanical superposition of the electronic and phononic states in a bulk solid.

High-harmonic generation in quantum spin systems

Shintaro Takayoshi, Yuta Murakami, and Philipp Werner

Phys. Rev. B 99, 184303 (2019) - Published 20 May, 2019

High-harmonic generation (HHG), a nonlinear response to strong laser driving, has been studied extensively for electron systems excited by the laser electric field. Here, the authors extend this concept to quantum spin systems driven by the laser magnetic field and propose a novel probe for the magnetic structure. The radiation emitted by time-dependent magnetic dipoles exhibits HHG spectra with plateau structures, whose cutoff energies correspond to the energy scale of the magnetic excitations. This maps out an exciting route for the implementation of HHG in solids. In addition, the similarities and the differences between HHG in electron and spin systems are also discussed.

Density functional perturbation theory within noncollinear magnetism

Fabio Ricci, Sergei Prokhorenko, Marc Torrent, Matthieu J. Verstraete, and Eric Bousquet

Phys. Rev. B 99, 184404 (2019) - Published 6 May, 2019

Density functional perturbation theory is a well-established and very powerful technique to compute observable response properties of materials from first principles. To date, its extension to noncollinear magnetism has not been considered, while there is strong pressure for such a development from emergent fields such as spintronics and spinorbitronics. In this paper, the formalism of density functional perturbation theory for noncollinear magnetism is developed and analyzed by exploiting locally collinear spin-polarized exchange-correlation functionals

Fine-tuning of canted magnetization in stepped Fe films through thickness variation, Au capping, and quantum confinement

M. Dąbrowski, M. Cinal, A. K. Schmid, J. Kirschner, and M. Przybylski

Phys. Rev. B 99, 184420 (2019) - Published 16 May, 2019

Magnetization switching by voltage pulses, microwaves, and optical pulses can be largely facilitated by canted orientation of magnetization. Here, the authors demonstrate that a canted magnetization with virtually any orientation can be achieved for thin Fe films, grown on a stepped surface. The canted state can be tuned by varying the film thickness, capping with an Au overlayer, and by taking advantage of magnetic anisotropy oscillations due to quantum well states. The observed evolution of tilted magnetization is accurately reproduced within a phenomenological model and is explained with the competition of three first-order magnetic anisotropy terms.

First-order valence transition: Neutron diffraction, inelastic neutron scattering, and x-ray absorption investigations on the double perovskite Ba2PrRu0.9Ir0.1O6

J. Sannigrahi, D. T. Adroja, C. Ritter, W. Kockelmann, A. D. Hillier, K. S. Knight, A. T. Boothroyd, M. Wakeshima, Y. Hinatsu, J. F. W. Mosselmans, and S. Ramos

Phys. Rev. B 99, 184440 (2019) - Published 28 May, 2019

Strongly correlated electron systems having strong hybridization between localized 4f electrons and conduction electrons exhibit anomalous behavior, e.g., heavy-fermion effects, Kondo effect, valence fluctuations, and many more. Among these, valence fluctuations are the most interesting and there are only a handful of compounds that exhibit a first-order valence transition. Here, the authors have provided direct confirmation of the first-order valence transition in Ba2PrRu0.9Ir0.1O6 using multiple techniques. This compound is the first system to exhibit multiple degrees of freedom with temperature, i.e., a structural phase transition, antiferromagnetic and ferromagnetic ordering, and a first-order valence transition.

Strongly correlated electron systems having strong hybridization between localized 4f electrons and conduction electrons exhibit anomalous behavior, e.g., heavy-fermion effects, Kondo effect, valence fluctuations, and many more. Among these, valence fluctuations are the most interesting and there are only a handful of compounds that exhibit a first-order valence transition. Here, the authors have provided direct confirmation of the first-order valence transition in Ba2PrRu0.9Ir0.1O6 using multiple techniques. This compound is the first system to exhibit multiple degrees of freedom with temperature, i.e., a structural phase transition, antiferromagnetic and ferromagnetic ordering, and a first-order valence transition.
