Approaching the quantum critical point in a highly correlated all-in–all-out antiferromagnet

Yishu Wang, T. F. Rosenbaum, D. Prabhakaran, A. T. Boothroyd, and Yejun Feng

Phys. Rev. B 101, 220404(R) (2020) - Published 4 June, 2020

All-in–all-out (AIAO) antiferromagnets demonstrate vividly the effects of correlated charge and spin with strong spin-orbit coupling. Here, using resonant magnetic x-ray diffraction, the authors directly track the evolution of AIAO order in the pyrochlore Sm2Ir2O7 across a pressure-tuned quantum critical point. The results demonstrate a powerful approach to the quantum critical state driven by electron correlations U/t and spin orbit coupling λ/t. The authors find prominent Ising-type spin fluctuations under pressure instead of the Heisenberg-type seen via chemical doping. This work also circumscribes the region of interest for the putative magnetic Weyl semimetal state in Pressure-Temperature space.

Travis J. Volz, Stefan J. Turneaure, Surinder M. Sharma, and Y. M. Gupta

Phys. Rev. B 101, 224109 (2020) - Published 9 June, 2020

During shock wave compression at about 500,000 atm of pressure and of about 100 nanoseconds duration, graphite is transformed into either hexagonal diamond or cubic diamond, depending on the crystal structure of the graphite crystallites that make up the sample. The figure shows x-ray diffraction data for two types of graphite: (a) and (b) show data for graphite crystallites having hexagonal structure, while (c) and (d) show data for graphite crystallites having turbostratic structure.

Markovian entanglement dynamics under locally scrambled quantum evolution

Wei-Ting Kuo, A. A. Akhtar, Daniel P. Arovas, and Yi-Zhuang You

Phys. Rev. B 101, 224202 (2020) - Published 8 June, 2020

There has been much recent interest in understanding entanglement dynamics and operator spreading in the Haar random circuit and Brownian circuit, which can be unified as locally scrambled quantum evolutions. Here, the authors prove that the entanglement dynamics for such quantum dynamics is Markovian and introduce the entanglement feature formulation to describe entanglement dynamics with an imaginary-time Schrödinger equation. This work opens up new possibilities to apply the quantum many-body physics techniques to tackle the entanglement dynamics problem.

Interlayer exchange coupling and spin Hall effect through an Ir-doped Cu nonmagnetic layer

Hiroto Masuda, Takeshi Seki, Yong-Chang Lau, Takahide Kubota, and Koki Takanashi

Phys. Rev. B 101, 224413 (2020) - Published 8 June, 2020

Controllable antiferromagnetic alignment of magnetizations is vital for the systematic study of antiferromagnetic spintronics. Along this path, antiferromagnetically coupled metallic superlattices are promising systems, exploiting the interlayer exchange coupling. Here, the authors report that, as a spacer-layer material sandwiched between ferromagnetic cobalt layers, nonmagnetic Ir-doped Cu exhibits simultaneously a definite interlayer exchange coupling and an appreciable spin-orbit torque. This experimental demonstration and findings offer an avenue to antiferromagnetic spintronics, based on antiferromagnetically coupled metallic superlattices.

Anomalous low-frequency conductivity in easy-plane XXZ spin chains

Utkarsh Agrawal, Sarang Gopalakrishnan, Romain Vasseur, and Brayden Ware

Phys. Rev. B 101, 224415 (2020) - Published 11 June, 2020

Computing the conductivity of interacting systems at nonzero temperature is a fundamental challenge. In integrable systems, the framework of generalized hydrodynamics lets one access the dc limit. Here, the authors combine generalized hydrodynamics with sum rules and locality to compute the ac conductivity of the XXZ spin chain (or, equivalently, interacting spinless fermions). Generically, it diverges at low frequencies, but for special “commensurate” parameters it has a finite limit. These results explain longstanding puzzles regarding the discontinuous parameter dependence of the dc response.

Sustained coherent spin wave emission using frequency combs

S. Muralidhar, A. A. Awad, A. Alemán, R. Khymyn, M. Dvornik, D. Hanstorp, and J. Åkerman

Phys. Rev. B 101, 224423 (2020) - Published 15 June, 2020

While rapid demagnetization of magnetic metals, driven by a laser pulse, can excite spin waves with high efficiency, they dissipate faster than the typical laser pulse repetition rate, precluding any continuous spin-wave generation. Here, the authors combine a gigahertz femtosecond laser comb with a Brillouin light scattering microscope to excite and detect sustained, coherent spin waves. Both localized and propagating spin waves can be excited with tailored wave vectors and a laser power dependent amplitude obeying Bloch’s T32 law.

Collective coordinate study of spin-wave emission from a dynamic domain wall

Gen Tatara and Rubén M. Otxoa de Zuazola

Phys. Rev. B 101, 224425 (2020) - Published 22 June, 2020

Radiation from a dynamic soliton is an issue of fundamental interest. Here, the authors study the emission from a domain wall in a ferromagnet taking into account the collective coordinate for the modulation of the wall thickness (breathing mode) in addition to the conventional coordinates, describing the sliding motion and the tilting angle of the wall plane. The breathing mode is shown to have a linear coupling to the fluctuation (spin wave), hence, it is the dominant source of spin-wave emission. The wave profile of the emitted spin wave is identified and the contribution to the Gilbert damping parameter due to the emission is estimated.

Electronic charge transfer driven by spin cycloidal structure

Y. Ishii, S. Horio, Y. Noda, M. Hiraishi, H. Okabe, M. Miyazaki, S. Takeshita, A. Koda, K. M. Kojima, R. Kadono, H. Sagayama, H. Nakao, Y. Murakami, and H. Kimura

Phys. Rev. B 101, 224436 (2020) - Published 29 June, 2020

The spin cycloidal structure is known as the origin of ferroelectricity in the magnets that are called multiferroics. Although these materials have been studied intensively for some decades, the local ferroelectric mechanism remains elusive. Here, the authors demonstrate that local charge transfer at ligand oxygen sites is driven by the spin cycloidal structure. They achieve this by observing induced spin polarization at oxygen sites with the use of synchrotron x-ray and muon spin rotation techniques. This leads to a better understanding of local electromagnetic coupling in multiferroics.

Topological theory of Lieb-Schultz-Mattis theorems in quantum spin systems

Dominic V. Else and Ryan Thorngren

Phys. Rev. B 101, 224437 (2020) - Published 29 June, 2020

Exploring the consequences of the arrangement of spins and its space-group symmetry, a systematic theory is given to determine under what circumstances the ground state of a quantum magnet must be a nontrivial quantum spin liquid if no ordering is observed. This generalizes the famous Lieb-Schultz-Mattis theorem. The theory places the theorem and its generalizations into the context of the general theory of topological phases of matter with space-group symmetries.

Optical enhancement of superconductivity via targeted destruction of charge density waves

Hossein Dehghani, Zachary M. Raines, Victor M. Galitski, and Mohammad Hafezi

Phys. Rev. B 101, 224506 (2020) - Published 8 June, 2020

Recently, there has been much interest in enhancing superconductivity using optical toolboxes. Here, motivated by the recent experimental advances in engineering surface plasmon polaritons, the authors propose a new method for enhancing superconductivity in cuprates via melting the collective fluctuations of the competing orders. Exploiting the fact that, in cuprates, superconductivity and charge density waves compete with each other, they derive the optical properties of the gapless collective fluctuations of the charge density wave. It is demonstrated that by using an intermediate surface plasmon polariton material, these collective modes can be excited optically. This leads to a more efficient melting of the charge density wave, whereby stronger enhancements of superconductivity can be achieved.

Nematic superconductivity in twisted bilayer graphene

Dmitry V. Chichinadze, Laura Classen, and Andrey V. Chubukov

Phys. Rev. B 101, 224513 (2020) - Published 26 June, 2020

Twisted bilayer graphene displays insulating and superconducting phases caused by flattening of its energy band. In the superconducting dome near hole half-filling, the threefold lattice rotation symmetry is broken, and the superconductor is also a nematic. The authors argue that superconductivity can be properly described by a patch model near twelve Van Hove points and show that there is nearly equal attractive interaction in two different superconducting channels. They go on to explicitly demonstrate that when both orders develop, the superconducting state is also a nematic.

Controllable antiferromagnetic alignment of magnetizations is vital for the systematic study of antiferromagnetic spintronics. Along this path, antiferromagnetically coupled metallic superlattices are promising systems, exploiting the interlayer exchange coupling. Here, the authors report that, as a spacer-layer material sandwiched between ferromagnetic cobalt layers, nonmagnetic Ir-doped Cu exhibits simultaneously a definite interlayer exchange coupling and an appreciable spin-orbit torque. This experimental demonstration and findings offer an avenue to antiferromagnetic spintronics, based on antiferromagnetically coupled metallic superlattices.

Phys. Rev. B 101, 224415 (2020) - Published 11 June, 2020

Computing the conductivity of interacting systems at nonzero temperature is a fundamental challenge. In integrable systems, the framework of generalized hydrodynamics lets one access the dc limit. Here, the authors combine generalized hydrodynamics with sum rules and locality to compute the ac conductivity of the XXZ spin chain (or, equivalently, interacting spinless fermions). Generically, it diverges at low frequencies, but for special “commensurate” parameters it has a finite limit. These results explain longstanding puzzles regarding the discontinuous parameter dependence of the dc response.

While rapid demagnetization of magnetic metals, driven by a laser pulse, can excite spin waves with high efficiency, they dissipate faster than the typical laser pulse repetition rate, precluding any continuous spin-wave generation. Here, the authors combine a gigahertz femtosecond laser comb with a Brillouin light scattering microscope to excite and detect sustained, coherent spin waves. Both localized and propagating spin waves can be excited with tailored wave vectors and a laser power dependent amplitude obeying Bloch’s T32 law.

Phys. Rev. B 101, 224425 (2020) - Published 22 June, 2020

Radiation from a dynamic soliton is an issue of fundamental interest. Here, the authors study the emission from a domain wall in a ferromagnet taking into account the collective coordinate for the modulation of the wall thickness (breathing mode) in addition to the conventional coordinates, describing the sliding motion and the tilting angle of the wall plane. The breathing mode is shown to have a linear coupling to the fluctuation (spin wave), hence, it is the dominant source of spin-wave emission. The wave profile of the emitted spin wave is identified and the contribution to the Gilbert damping parameter due to the emission is estimated.

The spin cycloidal structure is known as the origin of ferroelectricity in the magnets that are called multiferroics. Although these materials have been studied intensively for some decades, the local ferroelectric mechanism remains elusive. Here, the authors demonstrate that local charge transfer at ligand oxygen sites is driven by the spin cycloidal structure. They achieve this by observing induced spin polarization at oxygen sites with the use of synchrotron x-ray and muon spin rotation techniques. This leads to a better understanding of local electromagnetic coupling in multiferroics.

Topological theory of Lieb-Schultz-Mattis theorems in quantum spin systems

Phys. Rev. B 101, 224437 (2020) - Published 29 June, 2020

Exploring the consequences of the arrangement of spins and its space-group symmetry, a systematic theory is given to determine under what circumstances the ground state of a quantum magnet must be a nontrivial quantum spin liquid if no ordering is observed. This generalizes the famous Lieb-Schultz-Mattis theorem. The theory places the theorem and its generalizations into the context of the general theory of topological phases of matter with space-group symmetries.

Recently, there has been much interest in enhancing superconductivity using optical toolboxes. Here, motivated by the recent experimental advances in engineering surface plasmon polaritons, the authors propose a new method for enhancing superconductivity in cuprates via melting the collective fluctuations of the competing orders. Exploiting the fact that, in cuprates, superconductivity and charge density waves compete with each other, they derive the optical properties of the gapless collective fluctuations of the charge density wave. It is demonstrated that by using an intermediate surface plasmon polariton material, these collective modes can be excited optically. This leads to a more efficient melting of the charge density wave, whereby stronger enhancements of superconductivity can be achieved.

Nematic superconductivity in twisted bilayer graphene

Phys. Rev. B 101, 224513 (2020) - Published 26 June, 2020

Twisted bilayer graphene displays insulating and superconducting phases caused by flattening of its energy band. In the superconducting dome near hole half-filling, the threefold lattice rotation symmetry is broken, and the superconductor is also a nematic. The authors argue that superconductivity can be properly described by a patch model near twelve Van Hove points and show that there is nearly equal attractive interaction in two different superconducting channels. They go on to explicitly demonstrate that when both orders develop, the superconducting state is also a nematic.
