Nonequilibrium spin transport in integrable spin chains: Persistent currents and emergence of magnetic domains

Andrea De Luca, Mario Collura, and Jacopo De Nardis

Phys. Rev. B 96, 020403(R) (2017) - Published 6 July, 2017

The nonequilibrium dynamics of isolated many-body quantum systems leads generically to the emergence of standard thermal ensembles. However, some models, denoted as integrable, can display nontrivial steady states with a large memory of the initial state. This is due to the presence of conserved quantities constraining the unitary dynamics. Here, the authors show that in interacting integrable spin chains there exist also conserved operators that are responsible for ballistic spin transport. Such conserved operators highly influence both the equilibrium and nonequilibrium physics: at equilibrium they are responsible for a nonvanishing spin Drude weight even at half filling, while in the nonequilibrium case they are responsible for out-of-equilibrium steady states characterized by persistent spin currents or dynamically expanding magnetic domains.

Information propagation in isolated quantum systems

David J. Luitz and Yevgeny Bar Lev

Phys. Rev. B 96, 020406(R) (2017) - Published 12 July, 2017

How fast does quantum information spread in isolated quantum systems? The authors address this question using out-of-time order correlation functions and find that information spreads behind a power law front in disordered spin chains, with a characteristic exponent, which is related to the exponent of the power law growth of the entanglement entropy. The authors also observe that disorder inhibits information spreading and leads to unsaturated Lieb-Robinson bounds.

Three-dimensional dispersion of spin waves measured in NiO by resonant inelastic x-ray scattering

D. Betto, Y. Y. Peng, S. B. Porter, G. Berti, A. Calloni, G. Ghiringhelli, and N. B. Brookes

Phys. Rev. B 96, 020409(R) (2017) - Published 20 July, 2017

The authors have investigated the dispersion of magnetic excitations in thin films of antiferromagnetic NiO using resonant inelastic x-ray scattering (RIXS) at the L3 edge of nickel. They demonstrate here that, thanks to the recent improvements in energy resolution and scattering geometry, soft x-ray RIXS is a valid complement to inelastic neutron scattering in this field because it allows a clear identification of the spin-wave peaks not only in bulk crystals but also in thin films and heterostructures too small for neutron studies. Moreover, the spin-wave dispersion measured along three high-symmetry directions of the 3D fcc Brillouin zone allows an accurate determination of the main super-exchange integral J′ that establishes the antiferromagnetic structure of NiO. This report demonstrates definitively that RIXS is not confined to 2D materials such as cuprates and can be a useful tool for the study of magnetic interaction in a wide class of 3d transition metal systems.

Relativistic theory of magnetic inertia in ultrafast spin dynamics

Ritwik Mondal, Marco Berritta, Ashis K. Nandy, and Peter M. Oppeneer

Phys. Rev. B 96, 024425 (2017) - Published 18 July, 2017

In the field of ultrafast spin dynamics, magnetic inertia (spin nutation) is considered to hold great promise for achieving ultrafast magnetization switching. However, the fundamental origin of magnetic inertial dynamics is unknown. Here, the authors derive a complete theory of spin dynamics, including magnetic inertia, from fundamental Dirac theory. They show that magnetic inertia exists for any single Dirac particle and that it is a higher-order relativistic spin-orbit coupling effect compared to Gilbert damping. Magnetic inertia is therefore expected to play a role only on an ultrashort subpicosecond timescale.

Insight into the Dzyaloshinskii-Moriya interaction through first-principles study of chiral magnetic structures

L. M. Sandratskii

Phys. Rev. B 96, 024450 (2017) - Published 31 July, 2017

This work advances a physical picture of the Dzyaloshinskii-Moriya interaction (DMI), capable of addressing the apparently contradicting conclusions of recent studies about the location of the DMI energy in the real and reciprocal space as well as about the relation between the values of atomic moments and DMI strength. It is demonstrated on the example of a Co/Pt bilayer how DMI emerges from the chirality-dependent hybridization of the Co and Pt magnetic-spiral states under the influence of spin-orbit coupling and broken spatial inversion.

Disorder and superfluid density in overdoped cuprate superconductors

N. R. Lee-Hone, J. S. Dodge, and D. M. Broun

Phys. Rev. B 96, 024501 (2017) - Published 5 July, 2017

One of the hallmarks of clean, d-wave superconductivity is a linear temperature dependence of superfluid density in the low-temperature limit. Here, the authors show that weak scattering, combined with a realistic model of the cuprate Fermi surface, allows the linear behavior of superfluid density to persist in the presence of disorder even in the regime where the superfluid density and the transition temperature are strongly suppressed from their clean-limit values. This leads to a superfluid density that is both correlated with the transition temperature and linear in temperature, consistent with recent experiments on overdoped La2-xSrxCuO4.

Insight into the Dzyaloshinskii-Moriya interaction through first-principles study of chiral magnetic structures

L. M. Sandratskii

Phys. Rev. B 96, 024450 (2017) - Published 31 July, 2017

This work advances a physical picture of the Dzyaloshinskii-Moriya interaction (DMI), capable of addressing the apparently contradicting conclusions of recent studies about the location of the DMI energy in the real and reciprocal space as well as about the relation between the values of atomic moments and DMI strength. It is demonstrated on the example of a Co/Pt bilayer how DMI emerges from the chirality-dependent hybridization of the Co and Pt magnetic-spiral states under the influence of spin-orbit coupling and broken spatial inversion.

Superfluidity and superconductivity

Disorder and superfluid density in overdoped cuprate superconductors

Phys. Rev. B 96, 024501 (2017) - Published 5 July, 2017

One of the hallmarks of clean, d-wave superconductivity is a linear temperature dependence of superfluid density in the low-temperature limit. Here, the authors show that weak scattering, combined with a realistic model of the cuprate Fermi surface, allows the linear behavior of superfluid density to persist in the presence of disorder even in the regime where the superfluid density and the transition temperature are strongly suppressed from their clean-limit values. This leads to a superfluid density that is both correlated with the transition temperature and linear in temperature, consistent with recent experiments on overdoped La2-xSrxCuO4.
