Probing superfluid He4 with high-frequency nanomechanical resonators down to millikelvin temperatures

A. M. Guénault, A. Guthrie, R. P. Haley, S. Kafanov, Yu. A. Pashkin, G. R. Pickett, M. Poole, R. Schanen, V. Tsepelin, D. E. Zmeev, E. Collin, O. Maillet, and R. Gazizulin

Phys. Rev. B 100, 020506(R) (2019) - Published 17 July, 2019

Superfluids, such as superfluid 3He and 4He, exhibit a broad range of quantum phenomena and excitations, which are unique to these systems. Nanoscale mechanical resonators are highly sensitive force detectors with the ability to operate over many orders of magnitude in damping. Using nanomechanical doubly clamped beams, the authors probe superfluid 4He from the superfluid transition temperature down to millikelvin temperatures. They demonstrate excellent agreement with a ballistic model, incorporating thermal quasiparticles with acoustic emission limiting performance at the lowest temperatures.

Room temperature local nematicity in FeSe superconductor

R. J. Koch, T. Konstantinova, M. Abeykoon, A. Wang, C. Petrovic, Y. Zhu, E. S. Bozin, and S. J. L. Billinge

Phys. Rev. B 100, 020501(R) (2019) - Published 3 July, 2019

Electronic nematicity may be crucial for understanding the superconductivity in FeSe but its origin is still controversial. Here, the authors report the unexpected result, from local structural measurements, that nematic fluctuations exist preformed at temperatures far above the transition to the long-range-ordered nematic state. Perhaps even more surprisingly, the amplitude of the local nematicity is always larger than in the long-range ordered nematic state, suggesting that local nematic fluctuations persist even into the ordered state.

Unconventional pairing in single FeSe layers

Phys. Rev. B 100, 020503(R) (2019) - Published 11 July, 2019

Superconductivity in single FeSe layers on SrTiO3 shows a much higher critical temperature Tc than in bulk FeSe, illustrating the potential of interface engineering. Yet the underlying mechanism of boosting Tc is not understood. Both conventional and unconventional pairing mechanisms have been suggested to be responsible for this effect. Here, the authors show experimentally that phonons do not contribute significantly to the high Tc but instead the intrinsic spin fluctuations of the electrons themselves lead to Cooper pairing.

Second-order Dirac superconductors and magnetic field induced Majorana hinge modes

Sayed Ali Akbar Ghorashi, Xiang Hu, Taylor L. Hughes, and Enrico Rossi

Phys. Rev. B 100, 020509(R) (2019) - Published 31 July, 2019

Higher-order topological superconductors (HOTSCs) are a new class of topological materials that in three dimensions are characterized by gapped bulk and surface states and gapless hinge modes. Here, the authors identify two new groups of HOTSCs: (i) second-order Dirac superconductors, which have both topologically protected Dirac cones at the surface and topologically protected dispersionless Majorana states at the hinges; (ii) three-dimensional magnetic field-induced HOTSCs with helical Majorana hinge states, which are located at only two (or one) of the corners. The authors show that, using the sign of the magnetic field and the mirror-diagonal symmetry-breaking perturbation, the Majorana pairs can be tuned to be at a specific corner, leading to a highly tunable setup for realization and detection of helical Majorana states.

Observation of dynamical phase transitions in a topological nanomechanical system

Tian Tian, Yongguan Ke, Liang Zhang, Shaochun Lin, Zhifu Shi, Pu Huang, Chaohong Lee, and Jiangfeng Du

Phys. Rev. B 100, 024310 (2019) - Published 25 July, 2019

Here, the authors present a novel scheme to study dynamical phase transitions (DPTs) from topological edge states in the Su-Schrieffer-Heeger model. They utilize eight coupled nanomechanical oscillators to simulate the quantum quenches and observe DPTs via directly measuring the Pancharatnam geometric phase in the experiment. The robustness of the DPT and its relation to equilibrium phases are explored. This nanomechanical lattice with its multiple modes, high quality factor, and temporal configurability offers unique advantages for research into nonequilibrium phenomena via an artificial solid-state platform.

Frustrated spin-12 Heisenberg magnet on a square-lattice bilayer: High-order study of the quantum critical behavior of the J1J2J1 model

R. F. Bishop, P. H. Y. Li, O. Götze, and J. Richter

Phys. Rev. B 100, 024401 (2019) - Published 1 July, 2019

The frustrated spin-½ J1-J2 Heisenberg antiferromagnet on the 2D square lattice is a paradigmatic model of quantum magnetism. Despite extensive investigations over the last 30 years, no consensus has emerged for its zero-temperature quantum phase diagram. The authors explore its bilayer J1-J2-J1┴ counterpart by including an exchange coupling J1┴ between partner sites on the two layers. As well as being of great interest in its own right, the model provides considerable insight into the single-layer case by expanding to a two-parameter regime that includes the monolayer as a single slice.

Spin excitations of magnetoelectric LiNiPO4 in multiple magnetic phases

In magnetoelectric (ME) materials, magnetic moments and electric polarization are entangled, leading to the static and optical ME effects. This can be used in logical devices or for the manipulation of electromagnetic radiation in the GHz and THz spectral range where the oscillating magnetic moments absorb radiation. The authors use THz spectroscopy to study LiNiPO4, a four-spin system known to exhibit the static ME effect. Using linearly polarized THz radiation, they show that beside ordinary magnon resonances excited by the magnetic field of radiation there are electromagnons and ME spin excitations activated by the electric field of radiation, thus demonstrating that spin and charge dynamics are coupled in LiNiPO4. They refine the spin Hamiltonian parameters by mapping the spin resonance spectrum over a broad magnetic field range and fitting it with a mean-field spin model.

Laser-driven quantum magnonics and terahertz dynamics of the order parameter in antiferromagnets

Ultrashort laser pulses can induce picosecond coherent spin precession, described in terms of classical Landau-Lifshitz equations of motion. In antiferromagnets, the optical generation of pairs of high-energy magnons results in coherent 20-THz longitudinal spin oscillations. In a joint theoretical and experimental effort, the authors analyze here this controversial dynamical regime, investigating the dependence of spin dynamics on several parameters, such as temperature, polarization, and fluence. The derivation of an adequate equation of motion requires a quantum mechanical treatment, which predicts also entanglement between the pairs of photogenerated magnons.

Ultrashort laser pulses can induce picosecond coherent spin precession, described in terms of classical Landau-Lifshitz equations of motion. In antiferromagnets, the optical generation of pairs of high-energy magnons results in coherent 20-THz longitudinal spin oscillations. In a joint theoretical and experimental effort, the authors analyze here this controversial dynamical regime, investigating the dependence of spin dynamics on several parameters, such as temperature, polarization, and fluence. The derivation of an adequate equation of motion requires a quantum mechanical treatment, which predicts also entanglement between the pairs of photogenerated magnons.
