Diamagnetic response of a superconducting surface superstructure: Si(111)-7×3-In

Yanfu Wu, Ming-Chao Duan, Ningning Liu, Gang Yao, Dandan Guan, Shiyong Wang, Yao-Yi Li, Hao Zheng, Canhua Liu, and Jin-Feng Jia

Phys. Rev. B 99, 140506(R) (2019) - Published 18 April, 2019

How does one detect the Meissner effect in ultrathin superconducting films that are usually extremely sensitive to air? Here, the authors succeed in observing the diamagnetic response of a superconducting surface superstructure by using an insitu two-coil mutual inductance technique embedded in a specially designed scanning tunneling microscope. The diamagnetic measurement allows for the calculation of the penetration depth, which provides invaluable information about the nature of superconductivity and the symmetry of the underlying order parameter.

Magnon-photon coupling in the noncollinear magnetic insulator Cu2OSeO3

L. V. Abdurakhimov, S. Khan, N. A. Panjwani, J. D. Breeze, M. Mochizuki, S. Seki, Y. Tokura, J. J. L. Morton, and H. Kurebayashi

Phys. Rev. B 99, 140401(R) (2019) - Published 3 April, 2019

In chiral magnets, nontrivial spin textures can be realized due to the relativistic spin-orbit Dzyaloshinskii-Moriya interactions between the magnetic moments of unpaired electrons. In particular, a helical magnetic structure can be formed, in which magnetic moments spiral around the helical axis. Here, the authors demonstrate that collective spin excitations of the helical structure (helimagnons) can couple strongly to microwave cavity photons, resulting in the formation of a hybrid state – the helimagnon polariton.

Distinct magnetotransport and orbital fingerprints of chiral bobbers

M. Redies, F. R. Lux, J.-P. Hanke, P. M. Buhl, G. P. Müller, N. S. Kiselev, S. Blügel, and Y. Mokrousov

Phys. Rev. B 99, 140407(R) (2019) - Published 12 April, 2019

Based on theoretical arguments, the authors provide a clear pathway to utilizing a new chiral particle – a chiral bobber – for the purposes of future spintronics. They discover that these novel chiral states possess inherent transport traits that allow for their unambiguous electrical detection in systems comprising several types of chiral states. The unique properties of bobbers are rooted in the nontrivial spin topology of these particles, which also bear great potential for cognitive computing.

Low-temperature infrared dielectric function of hyperbolic α-quartz

Christopher J. Winta, Martin Wolf, and Alexander Paarmann

Phys. Rev. B 99, 144308 (2019) - Published 22 April, 2019

Hyperbolic materials are attracting considerable interest in the nanophotonics community due to their ability to support highly directional, large-momentum states that can be utilized for, e.g., subdiffractional imaging or nanolithography. Here, the authors explore the infrared dielectric properties of α-quartz at low temperatures by performing infrared reflectivity measurements. The results imply remarkably high quality factors for polaritons in the pronounced hyperbolic spectral region of α-quartz as well as additional design opportunities for nanophotonic applications.

Phonon dispersion in MoS2

Hans Tornatzky, Roland Gillen, Hiroshi Uchiyama, and Janina Maultzsch

Phys. Rev. B 99, 144309 (2019) - Published 24 April, 2019

The phonon dispersion is one of the most fundamental properties of a crystalline material. It determines virtually all of its physical properties, including optical, electronic, mechanical, and thermal behavior. Despite its importance, the phonon dispersion of MoS2 – one of the most investigated two-dimensional semiconductors – has not been determined experimentally in relevant parts of the Brillouin zone. In a combined experimental and theoretical approach, the authors present comprehensively the entire phonon dispersion of a MoS2 crystal and determine displacement patterns, symmetries, and scattering intensities.

Stacking tunable interlayer magnetism in bilayer CrI3

Peiheng Jiang, Cong Wang, Dachuan Chen, Zhicheng Zhong, Zhe Yuan, Zhong-Yi Lu, and Wei Ji

Phys. Rev. B 99, 144401 (2019) - Published 1 April, 2019

Interlayer magnetic interactions between two-dimension van der Waals layers are often thought to be weak or even negligible and their mechanism is largely unexplored. Here, the authors propose a mechanism for these interactions in a CrI3 bilayer, based on the concept of covalent-like quasibonding, which offers significant alteration of interlayer wave-function hybridization but small energetic difference between different stacking configurations. While a near-collinear coupling between two parallel spin-polarized I 5p orbitals prefers interlayer ferromagnetism, a noncollinear one favors antiferromagnetism, which is tunable by surmounting a tiny energy barrier between two stacking orders. This explains experimental observations and suggests a strategy for designing interlayer magnetism.

Calculating spin transport properties from first principles: Spin currents

R. J. H. Wesselink, K. Gupta, Z. Yuan, and Paul J. Kelly

Phys. Rev. B 99, 144409 (2019) - Published 11 April, 2019

Experiments usually don’t measure things favored by theorists like Green’s functions or scattering matrices, rather, they measure chemical potentials and currents. Here, the authors have calculated local charge and spin currents in bulk platinum and permalloy from the results of relativistic first-principles quantum mechanical scattering calculations at finite temperatures. This makes it possible to extract spin transport parameters like the spin-flip diffusion length, spin Hall angle, and spin polarization. It opens up the exciting possibility of separating interface and bulk effects, a problem that plagues experimental studies on magnetic bilayers.

Ab initio theory of the Gibbs free energy and a hierarchy of local moment correlation functions in itinerant electron systems: The magnetism of the Mn3A materials class

Eduardo Mendive-Tapia and Julie B. Staunton

Phys. Rev. B 99, 144424 (2019) - Published 25 April, 2019

Phase diagrams and the temperature and field dependence of complex magnetic materials are described here by an abinitio theory. Consideration of fluctuating local degrees of freedom (‘local moments’), emerging from a material’s interacting itinerant electrons, produces naturally a picture of multisite magnetic interactions. Accurate prediction of the order of transitions and the role of both electronic and magnetoelastic effects in the Gibbs free energy coefficients are demonstrated by application to the widely varying frustrated magnetism of Mn3A .

Robust Majorana magic gates via measurements

Torsten Karzig, Yuval Oreg, Gil Refael, and Michael H. Freedman

Phys. Rev. B 99, 144521 (2019) - Published 24 April, 2019

High-fidelity π/8 phase gates are an essential ingredient for the majority of universal quantum computation proposals. Here, the authors present a new way of implementing a π/8 gate in Majorana-based qubits that eliminates the leading noise sources, expected to limit other approaches. The scheme employs a combination of measurements and quantum evolution to optimize the fidelity of the final state when a favorable set of measurement outcomes has been achieved and, at the same time, guarantees a high-success probability for obtaining such measurement outcomes.

Phys. Rev. B 99, 144424 (2019) - Published 25 April, 2019

Phase diagrams and the temperature and field dependence of complex magnetic materials are described here by an abinitio theory. Consideration of fluctuating local degrees of freedom (‘local moments’), emerging from a material’s interacting itinerant electrons, produces naturally a picture of multisite magnetic interactions. Accurate prediction of the order of transitions and the role of both electronic and magnetoelastic effects in the Gibbs free energy coefficients are demonstrated by application to the widely varying frustrated magnetism of Mn3A .

High-fidelity π/8 phase gates are an essential ingredient for the majority of universal quantum computation proposals. Here, the authors present a new way of implementing a π/8 gate in Majorana-based qubits that eliminates the leading noise sources, expected to limit other approaches. The scheme employs a combination of measurements and quantum evolution to optimize the fidelity of the final state when a favorable set of measurement outcomes has been achieved and, at the same time, guarantees a high-success probability for obtaining such measurement outcomes.
