Spectrum of collective excitations of a quantum fluid of polaritons

F. Claude, M. J. Jacquet, I. Carusotto, Q. Glorieux, E. Giacobino, and A. Bramati

Phys. Rev. B 107, 174507 (2023) - Published 8 May, 2023

The phenomenology of superfluids and Bose-Einstein condensates is generally understood in terms of quantum hydrodynamics, which depend on the dispersion of the collective excitation modes in the quantum fluid. Here, via the implementation of a high-resolution spectroscopy technique, the authors highlight the peculiarities of collective excitations of a polariton superfluid and reveal a wealth of phenomena intrinsically linked to the light-matter and driven-dissipative nature of their system, such as the observation of a ghost branch highlighted in red in the image.

Explicit formula for high-order sideband polarization by extreme tailoring of Feynman path integrals

Qile Wu and Mark S. Sherwin

Phys. Rev. B 107, 174308 (2023) - Published 18 May, 2023

The authors derive here an explicit formula for a nonperturbative nonlinear optical phenomena called high-order sideband generation (HSG). The formula is valid over a wide range of experimentally accessible conditions. The results indicate a way to extract information on band structures and nonequilibrium dephasing rates from HSG experiments with simple algebraic calculations. This work also provides hints for analysis of HSG in multiband systems with non-Abelian Berry curvatures, as well as interband processes in high-harmonic generation.

Magnetic phase diagram of the breathing-kagome antiferromagnet Nd3BWO9

D. Flavián, J. Nagl, S. Hayashida, M. Yan, O. Zaharko, T. Fennell, D. Khalyavin, Z. Yan, S. Gvasaliya, and A. Zheludev

Phys. Rev. B 107, 174406 (2023) - Published 5 May, 2023

The newly discovered Nd3BWO9 is a rare instance of a disorder-free magnet with an exchange topology interpolating between 2D kagome and 1D spin tubes. In this study, an array of measurements reveals its exotic phase diagram. The complex frustration mechanism results in several ordered phases, including two different, typically two-dimensional 1/3- magnetization plateaux. Meanwhile, one-dimensional tube correlations are unequivocally identified by signatures in both thermodynamic and microscopic probes.

Observation of hybrid magnetic skyrmion bubbles in Fe3Sn2 nanodisks

Lingyao Kong, Jin Tang, Weiwei Wang, Yaodong Wu, Jialiang Jiang, Yihao Wang, Junbo Li, Yimin Xiong, Mingliang Tian, and Haifeng Du

Phys. Rev. B 107, 174425 (2023) - Published 16 May, 2023

It has been widely established that there exist two types of magnetic bubbles. Here, the authors present the theory and experiment of a novel three-dimensional bubble state, referred to as the type-III bubble, which is composed of Néel-twisted skyrmions with topological charge Q = -1 in the near-surface layers and type-II bubbles with Q = 0 in the interior layers. Furthermore, the authors demonstrate a method for creating the type-III bubble and the topological magnetic transformation among the three types of bubbles.

Magnon dispersion in ferromagnetic SrRuO3

K. Jenni, S. Kunkemöller, A. Tewari, R. A. Ewings, Y. Sidis, A. Schneidewind, P. Steffens, A. A. Nugroho, and M. Braden

Phys. Rev. B 107, 174429 (2023) - Published 23 May, 2023

Magnetic excitations in the itinerant magnet SrRuO3 were studied by the combination of various neutron scattering techniques. Although a Heisenberg local-moment model well describes the low-energy magnon dispersion, severe suppression of intensities and stiffening of the dispersion at high energies, as well as a strong broadening, are clear finger prints of the itinerant character of magnetism in SrRuO3.

Magic angles and correlations in twisted nodal superconductors

Pavel A. Volkov, Justin H. Wilson, Kevin P. Lucht, and J. H. Pixley

Phys. Rev. B 107, 174506 (2023) - Published 4 May, 2023

Stacking 2D materials with a twist has proven to be a successful strategy to realize exotic phases of electrons. Here, the authors apply these ideas to intrinsic 2D nodal superconductors, showing a similar degree of control over neutral Dirac quasiparticles. Their velocity is quenched close to a “magic” angle, where interactions drive a time-reversal breaking phase transition. Gating and application of current and magnetic fields are shown to allow tuning their dispersion in future experiments and to open topological gaps.

Local density of states fluctuations in a two-dimensional superconductor as a probe of quantum diffusion

Mathieu Lizée, Matthias Stosiek, Igor Burmistrov, Tristan Cren, and Christophe Brun

Phys. Rev. B 107, 174508 (2023) - Published 8 May, 2023

Could disorder enhance superconductivity? Close to the Anderson transition, electronic wave functions show a peculiar multifractal structure, predicted to enhance Cooper pairing. Here, the authors probe the weak disorder limit using an atomic monolayer of lead with high-resolution scanning tunneling spectroscopy. They show that mesoscopic spatial fluctuations of the electronic density of states indicate coherent diffusion of electrons. They use these energy-dependent fluctuations to reveal tiny energy gap fluctuations and to extract the elastic mean free path, dephasing length, as theoretically expected.

Transformer spin-triplet superconductivity at the onset of isospin order in bilayer graphene

Zhiyu Dong, Andrey V. Chubukov, and Leonid Levitov

Phys. Rev. B 107, 174512 (2023) - Published 11 May, 2023

The recently discovered superconductivity in Bernal bilayer graphene features unique behavior that distinguishes it from conventional superconductors. Firstly, the onset of superconductivity is associated with the emergence of an isospin-polarized phase, driven by Stoner instability. Secondly, the superconductivity is activated by a magnetic field and persists beyond the Pauli limit. These properties have sparked the interest of researchers and prompted the search for a pairing mechanism that can account for these findings. This paper reports on recent progress in this quest.​

The recently discovered superconductivity in Bernal bilayer graphene features unique behavior that distinguishes it from conventional superconductors. Firstly, the onset of superconductivity is associated with the emergence of an isospin-polarized phase, driven by Stoner instability. Secondly, the superconductivity is activated by a magnetic field and persists beyond the Pauli limit. These properties have sparked the interest of researchers and prompted the search for a pairing mechanism that can account for these findings. This paper reports on recent progress in this quest.​
