Hung-Tzu Chang, Alexander Guggenmos, Scott K. Cushing, Yang Cui, Naseem Ud Din, Shree Ram Acharya, Ilana J. P. Molesky, Ulf Kleineberg, Volodymyr Turkowski, Talat S. Rahman, Daniel M. Neumark, and Stephen R. Leone

Phys. Rev. B 103, 064305 (2021) - Published 10 February, 2021

Thermalization and relaxation of photoexcited carriers play an important role in ultrafast demagnetization and photoinduced phase transitions. However, direct observation of carrier thermalization in metals is highly challenging due to its fast timescale. Here, the authors track the thermalization and relaxation of photoexcited electrons in nickel in real time with few-femtosecond core-level transient absorption spectroscopy. In addition, a method to extract carrier temperature from the core-level absorption spectrum is proposed and verified by the experimental results. This enables further applications of core-level spectroscopy to explore element- and, hence, domain-specific carrier dynamics in metallic alloys and multilayers.

Spin structure and resonant driving of spin-12 defects in SiC

Benedikt Tissot and Guido Burkard

Phys. Rev. B 103, 064106 (2021) - Published 19 February, 2021

Transition metal defects in silicon carbide are a promising platform for quantum information processing. The authors employ group theory, utilizing the symmetry of the crystal in the study of defects with one active electron in the d shell of the transition metal atom. With this, they obtain a deeper understanding of the spin structure as well as of the magnetic and optical selection rules and resonance properties for the defect. The developed theoretical description can be instrumental to perform and optimize spin control.

Eigenstate correlations around the many-body localization transition

K. S. Tikhonov and A. D. Mirlin

Phys. Rev. B 103, 064204 (2021) - Published 12 February, 2021

Many-body localization (MBL) addresses (de)localization in highly excited states of disordered interacting systems. The authors explore eigenstate correlations in the vicinity of the MBL transition, emphasizing that they can be measured on state-of-the-art quantum processors and simulators. In addition to the genuine many-body problem, localization on random regular graphs is considered, which serves as a toy model of the transition. Both models show remarkably similar behavior that includesergodicity of the delocalized phase, power-law enhancement of correlations at low frequency in the MBL phase, and maximalcorrelation between adjacent-in-energy states at the transition point.

Limits to magnetic quantum criticality from nuclear spins

Heike Eisenlohr and Matthias Vojta

Phys. Rev. B 103, 064405 (2021) - Published 3 February, 2021

Quantum critical systems are generically susceptible to small perturbations. Here, the authors study how the hyperfine coupling to nuclear spins modifies magnetic quantum phase transitions. Symmetry arguments allow one to distinguish two generic scenarios: either the disordered phase remains intact, then leading to a shift of the transition point, or the disordered phase is destroyed by nuclear-spin induced order, then replacing the phase transition by a crossover. For both scenarios, relevant observables and crossover scales are obtained within explicit model calculations.

Neutron scattering investigation of proposed Kosterlitz-Thouless transitions in the triangular-lattice Ising antiferromagnet TmMgGaO4

Zhiling Dun, Marcus Daum, Raju Baral, Henry E. Fischer, Huibo Cao, Yaohua Liu, Matthew B. Stone, Jose A. Rodriguez-Rivera, Eun Sang Choi, Qing Huang, Haidong Zhou, Martin Mourigal, and Benjamin A. Frandsen

Phys. Rev. B 103, 064424 (2021) - Published 18 February, 2021

The Kosterlitz-Thouless transition describes a topological phase transition in the 2D XY model resulting from the binding of vortex-antivortex pairs. Kosterlitz-Thouless physics can theoretically emerge in triangular Ising antiferromagnets by mapping magnetic moments onto a complex order parameter residing at the center of each triangle of the lattice. Here, the authors find supporting evidence for such physics in the rare-earth material TmMgGaO4 through neutron scattering and modeling studies of spin correlations in both real and reciprocal space. This research shows that dense spin systems, even in the presence of structural disorder, can be investigated and controlled in search for topological phase transitions.

Hydrodynamics of nonintegrable systems from a relaxation-time approximation

Javier Lopez-Piqueres, Brayden Ware, Sarang Gopalakrishnan, and Romain Vasseur

Phys. Rev. B 103, L060302 (2021) - Published 24 February, 2021

Many strongly interacting systems of experimental relevance are nearly integrable. A paradigm for studying such weakly nonintegrable systems has been lacking. Here, the authors extend a generalized hydrodynamics framework, which has been successfully used to study transport in integrable systems, in order to tackle the dynamics away from integrability. In doing so, the authors propose a simple ansatz in the form of a relaxation-time approximation for the collision integral, finding excellent agreement with first-principle numerical simulations.

Dynamics of a fractal set of first-order magnetic phase transitions in frustrated Lu2CoMnO6

Adra Carr, John Bowlan, Claudio Mazzoli, Colby Walker, Xiaxin Ding, Andi Barbour, Wen Hu, Stuart Wilkins, Jong Hyuk Kim, Nara Lee, Young Jai Choi, Shi-Zeng Lin, Richard L. Sandberg, and Vivien S. Zapf

Phys. Rev. B 103, L060401 (2021) - Published 4 February, 2021

Magnetic frustration can produce exotic spin configurations and dynamics. Here, the authors explore the seemingly simple competition between ferromagnetic nearest- and antiferromagnetic next-nearest neighbor interactions along Ising spin chains, as realized in the magnetoelectric compound Lu2CoMnO6. Commonly, this situation is described by the axial next-nearest-neighbor Ising model. For the first time, the authors measure and calculate its correlated magnetic dynamics, resulting from a characteristic fractal set of first-order phase boundaries. Experiments and Monte Carlo simulations reveal a dynamics slowdown while approaching the phase transition regime.

Probing the topology of the quantum analog of a classical skyrmion

O. M. Sotnikov, V. V. Mazurenko, J. Colbois, F. Mila, M. I. Katsnelson, and E. A. Stepanov

Phys. Rev. B 103, L060404 (2021) - Published 12 February, 2021

The standard theory of magnetic skyrmions essentially relies on the assumption that the local magnetization is a classical vector. In this paper, the authors introduce a novel quantum skyrmion state, and show that this quantum analog of a classical skyrmion can be fully characterized by a local operator defined on three neighboring sites, the quantum scalar chirality. They show that this observable is nearly constant inside the quantum skyrmion phase and can thus be used as an effective topological invariant.

Topological control of magnetic textures

H. Arava, F. Barrows, M. D. Stiles, and A. K. Petford-Long

Phys. Rev. B 103, L060407 (2021) - Published 25 February, 2021

The authors systematically reveal that magnetic textures can be controlled via topology, using discrete objects. A discrete formulation of the topological winding number is used to define the stray field from individual nanomagnets, which in turns controls the magnetic texture in a disk. The authors demonstrate experimentally that appropriate topological conditions can stabilize an energetically unfavorable structure, such as an antivortex in a permalloy disk. The topological argument holds even in coupled systems, leading, for example, to applications in neuromorphic computing.

The Kosterlitz-Thouless transition describes a topological phase transition in the 2D XY model resulting from the binding of vortex-antivortex pairs. Kosterlitz-Thouless physics can theoretically emerge in triangular Ising antiferromagnets by mapping magnetic moments onto a complex order parameter residing at the center of each triangle of the lattice. Here, the authors find supporting evidence for such physics in the rare-earth material TmMgGaO4 through neutron scattering and modeling studies of spin correlations in both real and reciprocal space. This research shows that dense spin systems, even in the presence of structural disorder, can be investigated and controlled in search for topological phase transitions.
