Enhancement of superconductivity mediated by antiferromagnetic squeezed magnons

Eirik Erlandsen, Akashdeep Kamra, Arne Brataas, and Asle Sudbø

Phys. Rev. B 100, 100503(R) (2019) - Published 25 September, 2019

Spin states in quantum antiferromagnets are coherent superpositions of “up” and “down” spin flips. The average spin on each sublattice associated with an antiferromagnetic magnon is, therefore, much larger than its unit net spin. Here, the authors demonstrate that proximity, which couples the electronic states in a metal asymmetrically to the two sublattices of an antiferromagnet, enhances the strength of the magnon-induced electronic interactions in the metal, and dramatically increases the transition temperature for the resulting magnon-mediated superconductivity.

Materials property prediction using symmetry-labeled graphs as atomic position independent descriptors

Peter Bjørn Jørgensen, Estefanía Garijo del Río, Mikkel N. Schmidt, and Karsten Wedel Jacobsen

Phys. Rev. B 100, 104114 (2019) - Published 26 September, 2019

Accurate property prediction for structures without knowledge of exact atomic positions is achieved with a machine-learning model. The model is formulated as neural-message passing on Voronoi graphs using a new method for the encoding of local symmetry information.

Negative piezoelectric response of van der Waals layered bismuth tellurohalides

Jinwoong Kim, Karin M. Rabe, and David Vanderbilt

Phys. Rev. B 100, 104115 (2019) - Published 30 September, 2019

While not physically forbidden, a negative piezoelectric response – defined as an enhancement of polarization under compression – is rare in nature. However, this effect has recently been found in several van der Waals bonded materials, among them the polar BiTeX (X=I, Cl, Br) compounds studied here. First-principles calculations reveal that their negative piezoelectric response is mainly induced by a charge-center shift of the Wannier functions (shown in the figure) under compression, especially on the halide, increasing the layer dipole moment and thus the polarization.

Prethermal quantum many-body Kapitza phases of periodically driven spin systems

Alessio Lerose, Jamir Marino, Andrea Gambassi, and Alessandro Silva

Phys. Rev. B 100, 104306 (2019) - Published 30 September, 2019

The action of external drive on a physical system can cause novel dynamical behavior with no counterpart in equilibrium. A paradigmatic example is provided by the so-called Kapitza pendulum, where the upside-down configuration of the rigid rod of the pendulum is made stable by modulating its suspension point periodically in time. The present work demonstrates that driving periodically a quantum many-body system with long-range interactions may generate a multiparticle analog of the Kapitza pendulum, which is stabilized against all possible microscopic quantum fluctuations.

Evolution of structural, magnetic, and transport properties in MnBi2−xSbxTe4

J.-Q. Yan, S. Okamoto, M. A. McGuire, A. F. May, R. J. McQueeney, and B. C. Sales

Phys. Rev. B 100, 104409 (2019) - Published 4 September, 2019

Here, the authors report a thorough study of the evolution of structural, magnetic, and electrical properties of MnBi2−xSbxTe4 single crystals. This investigation reveals an intimate correlation between the structural, magnetic, and transport properties. Partial substitution of Bi by Sb is an effective approach to tuning both the magnetism and the Fermi level, which are two key components of magnetic topological insulators. This work provides an important guide for exploring the topological properties in MnBi2Te4-based materials. The effect of doping on the magnetic properties also suggests complex competing interactions, which should be considered when tuning the magnetic properties.

Excitation of unidirectional exchange spin waves by a nanoscale magnetic grating

Jilei Chen, Tao Yu, Chuanpu Liu, Tao Liu, Marco Madami, Ka Shen, Jianyu Zhang, Sa Tu, Md Shah Alam, Ke Xia, Mingzhong Wu, Gianluca Gubbiotti, Yaroslav M. Blanter, Gerrit E. W. Bauer, and Haiming Yu

Phys. Rev. B 100, 104427 (2019) - Published 20 September, 2019

Unidirectional propagation of spin waves is key to the realization of magnonic logic devices. Here, the authors experimentally demonstrate excitations of unidirectional exchange spin waves by a nanoscale magnetic grating fabricated on an ultrathin yttrium iron garnet film. The authors explain and model the nearly perfect unidirectional excitation by the chirality of the magnetodipolar interactions. Reversal of the magnetic configurations changes the direction of the exchange spin waves. Such results raise the prospect of a chiral magnonic logic without the need for fragile surface states.

Light-induced nonequilibrium response of the superconducting cuprate La2−xSrxCuO4

Hiroaki Niwa, Naotaka Yoshikawa, Kaito Tomari, Ryusuke Matsunaga, Dongjoon Song, Hiroshi Eisaki, and Ryo Shimano

Phys. Rev. B 100, 104507 (2019) - Published 5 September, 2019

Recent observations of a light-induced superconducting-like state above Tc in stripe-ordered cuprate superconductors have triggered intensive theoretical and experimental studies to elucidate the mechanism. How the superconducting state of these cuprates is affected by photoexcitation has remained elusive even below Tc. Here, the authors perform optical pump-probe terahertz spectroscopy on La2−xSrxCuO4 where no long-range stripe order exists. The authors demonstrate that in this material, upon strong photoexcitation, the spectrum in the quasiequilibrium state is described by light-induced thermalization that exhibits a temperature gradient along the pump-penetration direction. The authors also show that a conventional method of analysis can lead to artifacts when the penetration-depth mismatch between the pump and probe can’t be neglected.

Here, the authors experimentally demonstrate excitations of unidirectional exchange spin waves by a nanoscale magnetic grating fabricated on an ultrathin yttrium iron garnet film. The authors explain and model the nearly perfect unidirectional excitation by the chirality of the magnetodipolar interactions. Reversal of the magnetic configurations changes the direction of the exchange spin waves. Such results raise the prospect of a chiral magnonic logic without the need for fragile surface states.

Recent observations of a light-induced superconducting-like state above Tc in stripe-ordered cuprate superconductors have triggered intensive theoretical and experimental studies to elucidate the mechanism. How the superconducting state of these cuprates is affected by photoexcitation has remained elusive even below Tc. Here, the authors perform optical pump-probe terahertz spectroscopy on La2−xSrxCuO4 where no long-range stripe order exists. The authors demonstrate that in this material, upon strong photoexcitation, the spectrum in the quasiequilibrium state is described by light-induced thermalization that exhibits a temperature gradient along the pump-penetration direction. The authors also show that a conventional method of analysis can lead to artifacts when the penetration-depth mismatch between the pump and probe can’t be neglected.
