Half moons are pinch points with dispersion

Han Yan (闫寒), Rico Pohle, and Nic Shannon

Phys. Rev. B 98, 140402(R) (2018) - Published 12 October, 2018

Frustrated magnetism provides a fascinating playground for realizing exotic states of matter, such as the spin liquid. A characteristic signature for a U(1) spin liquid is the “pinch point”, a distinctive singular pattern observed in neutron scattering experiments. Another pattern of an anisotropic ring, dubbed the “half moon”, often accompanies the pinch point. Here, the authors reveal the underlying physics linking the two signatures. The half moons are essentially pinch points inscribed on a dispersing band. By analyzing the kagome lattice–Heisenberg antiferromagnet, this work presents a detailed study of how a unifying field theory accounts for both features intuitively.

Quantized magnetic flux and the magnetohalon effect in a critical superconductor

Kun Chen and Boris Svistunov

Phys. Rev. B 98, 140503(R) (2018) - Published 11 October, 2018

If a solenoid is introduced into a superconductor at its critical temperature, the net magnetic flux is quantized. A nontrivial effect takes place at the transition between two adjacent values of the magnetic flux. On the approach to the critical point (corresponding to half-integer bare solenoid flux), the spatial distribution of magnetic flux splits into a half-integer core and a critically large halo carrying plus/minus one half of the flux quantum. The phenomenon is a direct counterpart of the recently revealed halon effect in terms of the quantized particle charge of a static impurity in the two-dimensional U(1) quantum-critical environment.

Velocity-dependent Lyapunov exponents in many-body quantum, semiclassical, and classical chaos

Vedika Khemani, David A. Huse, and Adam Nahum

Phys. Rev. B 98, 144304 (2018) - Published 16 October, 2018

It has been a long-standing challenge to expand the notion of exponential sensitivity to small perturbations in the initial conditions from the realm of classical chaos to that of many-body quantum systems. Recently, exponential growth in a measure known as the out-of-time-order commutator (OTOC) has been proposed as a diagnostic of chaos in the setting of many-body quantum systems. The authors examine the behavior of the OTOC along rays of different velocities for a variety of spatially local extended many-body quantum systems, both integrable and nonintegrable. They find that the velocity-dependent Lyapunov exponents are negative for velocities greater than a characteristic “butterfly speed”, which defines the light cone for the spreading of operators. It is demonstrated that a regime with well-defined positive Lyapunov exponents inside the light-cone may only exist for classical, semiclassical, weakly interacting, or large-N systems, but not for fully quantum systems with strong short-range interactions and local Hilbert space dimensions of order one.

Thermodynamic evidence of a second skyrmion lattice phase and tilted conical phase in Cu2OSeO3

M. Halder, A. Chacon, A. Bauer, W. Simeth, S. Mühlbauer, H. Berger, L. Heinen, M. Garst, A. Rosch, and C. Pfleiderer

Phys. Rev. B 98, 144429 (2018) - Published 19 October, 2018

Skyrmion lattices in magnetic materials represent long-range magnetic order featuring nontrivial topological winding. Here, magnetization, ac susceptibility, and specific heat data are reported that provide thermodynamic evidence of two disconnected skyrmion lattice phases in the same material, the cubic insulator Cu2OSeO3. The magnetization and susceptibility demonstrate, moreover, that the two phases are stabilized by two inherently different mechanisms. Whereas the high-temperature skyrmion phase originates in entropic effects driven by thermal fluctuations, the low-temperature skyrmion phase is due to conventional cubic magnetic anisotropies, previously thought to be too weak to be thermodynamically relevant.

Electrodynamics of Josephson junctions containing strong ferromagnets

D. Massarotti, N. Banerjee, R. Caruso, G. Rotoli, M. G. Blamire, and F. Tafuri

Phys. Rev. B 98, 144516 (2018) - Published 22 October, 2018

Triplet superconductivity, with equal-spin Cooper pairs, are of fundamental importance to develop an ultralow-dissipation version of spintronics with superconductors. The dynamical properties of Josephson junctions with triplet supercurrents have largely remained unexplored. Here, the authors analyze the phase dynamics of these junctions for possible applications in superconducting circuits. Remarkably, the junction electrodynamics can be reconstructed within the framework of the well-known resistively and capacitively shunted junction model with renormalized parameters, possibly providing a novel way to dynamically detect triplets.

Triplet superconductivity, with equal-spin Cooper pairs, are of fundamental importance to develop an ultralow-dissipation version of spintronics with superconductors. The dynamical properties of Josephson junctions with triplet supercurrents have largely remained unexplored. Here, the authors analyze the phase dynamics of these junctions for possible applications in superconducting circuits. Remarkably, the junction electrodynamics can be reconstructed within the framework of the well-known resistively and capacitively shunted junction model with renormalized parameters, possibly providing a novel way to dynamically detect triplets.
