Higher-order acoustic phonon oscillations in Au nanoparticles controlled by a sequence of ultrashort strain pulses generated by superdiffusive hot electrons

Yooleemi Shin, Yu Liu, Mircea Vomir, and Ji-Wan Kim

Phys. Rev. B 101, 020302(R) (2020) - Published 22 January, 2020

One of the quests in ultrafast plasmonics is the development of devices, based on surface plasmons and operating at high frequency and negligible heating conditions. Towards this goal, the authors use ultrashort strain pulses, generated by superdiffusive hot electrons to excite high-order spheroidal modes of Au nanoparticles. Their vibrations are accessed via periodic shifts of the surface plasmon band and further coherently controlled by a sequence of strain pulses. These results open new perspectives for ultrafast acoustoplasmonics towards the terahertz frequency regime.

Transient response of the spin Peltier effect revealed by lock-in thermoreflectance measurements

Takumi Yamazaki, Ryo Iguchi, Tadakatsu Ohkubo, Hosei Nagano, and Ken-ichi Uchida

Phys. Rev. B 101, 020415(R) (2020) - Published 28 January, 2020

The transient response and length scale of the spin Peltier effect (SPE) – heat-current generation due to magnon spin currents – are revealed by frequency-domain lock-in thermoreflectance. The amplitude of the SPE-induced temperature modulation decreases when the excitation frequency exceeds 1 kHz. The frequency dependence is determined by the characteristic length of the SPE, which is estimated to be 0.94 µm for yttrium iron garnet. This length is similar to, but smaller than, the length scale of the spin Seebeck effect, suggesting that the electrically excited magnons in SPE are of a different nature when compared with the thermally excited magnons in the spin Seebeck effect.

Self-doped Mott insulator for parent compounds of nickelate superconductors

Guang-Ming Zhang, Yi-feng Yang, and Fu-Chun Zhang

Phys. Rev. B 101, 020501(R) (2020) - Published 7 January, 2020

Motivated by analyses of the reported electrical resistivity and Hall coefficient data in the normal state, the authors propose that the parent compound of the newly discovered superconducting nickelate Nd1xSrxNiO2 is a self-doped Mott insulator, in which the low-density Nd 5d conduction electrons couple to localized Ni 3dx2y2 electrons to form Kondo spin singlets at low temperature. The antiferromagnetic long-range order is suppressed and an insulator-metal transition results.

Spin-polarized multiple Andreev reflections in spin-split superconductors

Bo Lu, Pablo Burset, and Yukio Tanaka

Phys. Rev. B 101, 020502(R) (2020) - Published 8 January, 2020

Superconductors with spin-split energy bands are an important building block for superconducting spintronic designs. Motivated by the recent measurement of tunneling quasiparticle currents between spin-split superconductors, this work investigates theoretically voltage-biased Josephson junctions of arbitrary transparency. The authors show that an exotic subharmonic gap structure arises due to spin-polarized multiple Andreev reflections (MARs), where the odd-order MARs split, but the even-order ones remain unaffected by the spin-split fields. These findings provide a tool to determine the amplitude and alignment of Zeeman fields in spin-split superconductors.

Intermittent dynamics of antiferromagnetic phase in inhomogeneous iron-based chalcogenide superconductor

Phys. Rev. B 101, 020508(R) (2020) - Published 31 January, 2020

Layered superconductors are electronically inhomogeneous systems, characterized by the interplay of charge, lattice, and magnetic degrees of freedom. Intrinsic phase separation and texturing at different length scales are natural consequences of this interplay. Here, the authors have studied atomic motion in nanodomains of an inhomogeneous iron-based superconductor with coexisting metallic and antiferromagnetic phases, exploiting evolution of speckles produced by coherent x-ray scattering. They show that the majority antiferromagnetic phase has an avalanchelike dynamics, which changes anomalously across the superconducting transition temperature. The results suggest relevance of glassy dynamics in the quantum phenomena occurring in inhomogeneous matter.

Quantum many-body scar states with emergent kinetic constraints and finite-entanglement revivals

Thomas Iadecola and Michael Schecter

Phys. Rev. B 101, 024306 (2020) - Published 29 January, 2020

Strongly interacting systems with quantum many-body scars exhibit persistent fidelity oscillations when prepared in a certain class of initial states, but otherwise undergo ergodic dynamics. Previous examples of scars have interpreted the characteristic periodic dynamics in terms of the precession of a macroscopic SU(2) spin in an effective magnetic field. Here, the authors uncover a new exactly solvable example of many-body scars in a spin-½ model and show that the scarred dynamics in this model evades such an interpretation. This unusual coherent dynamics arises due to an emergent kinetic constraint that endows the time-evolving many-body state with constant area-law entanglement. The model studied in this work is relevant to experiments on Rydberg-atom quantum simulators in the antiblockade regime.

Systematic derivation of realistic spin models for beyond-Heisenberg solids

Markus Hoffmann and Stefan Blügel

Phys. Rev. B 101, 024418 (2020) - Published 21 January, 2020

The magnetic properties of many ultrathin films on metal substrates cannot be explained by the Heisenberg exchange interaction. Other known interactions, such as the biquadratic or the four-spin interaction, are also insufficient. This suggests the existence of further multispin interactions. The authors provide a systematic derivation of those interactions based on a multiband Hubbard model combined with a downfolding technique and propose a three-spin interaction. They show that it is strong in the systems with Fe on Ru(0001) and Fe on Rh(111), and even comparable in size to the Heisenberg interaction.

Spin-dimer ground state driven by consecutive charge and orbital ordering transitions in the anionic mixed-valence compound Rb4O6

T. Knaflič, P. Jeglič, M. Komelj, A. Zorko, P. K. Biswas, A. N. Ponomaryov, S. A. Zvyagin, M. Reehuis, A. Hoser, M. Geiß, J. Janek, P. Adler, C. Felser, M. Jansen, and D. Arčon

Phys. Rev. B 101, 024419 (2020) - Published 22 January, 2020

A comprehensive study of the molecular mixed-valence compound Rb4O6 led the authors to the discovery of a peculiar π* orbital ordering transition of magnetic O2 anions within the charge ordered state, which promotes the formation of an orbital order-driven quantum spin state, composed of spin dimers. The experiments suggest that a delicate interplay between an electron-lattice coupling and Kugel-Khomskii-type superexchange in π-electron systems determines the magnetostructural properties. These results establish a fruitful analogy between π- and more conventional 3d-mixed-valence systems and push the research of such systems into new directions to tackle the intertwining of various active degrees of freedom.

Kohn-Luttinger correction to Tc in a phonon superconductor

Dan Phan and Andrey V. Chubukov

Phys. Rev. B 101, 024503 (2020) - Published 6 January, 2020

In recent years, there has been a surge of interest in superconductivity in low-carrier-density materials, propelled by advances in experimental studies in systems such as SrTiO3. Here, the authors analyze how the superconducting transition temperature Tc varies in two dimensions as one tunes the Fermi energy EF with respect to Debye frequency ωD of a pairing boson. The authors work at weak coupling, by which they go beyond lowest order in the coupling and find the values of Tc with the exact prefactor.

Interacting Majorana modes at surfaces of noncentrosymmetric superconductors

Janna E. Rückert, Gergő Roósz, and Carsten Timm

Phys. Rev. B 101, 024519 (2020) - Published 29 January, 2020

Majorana modes are currently receiving a lot of attention, in part because they may be useful for quantum computation. One proposed platform to realize a large number of Majorana zero-energy modes involves flat bands at surfaces of superconductors lacking inversion symmetry. Here, the authors investigate what happens to these flat Majorana bands if interactions beyond BCS mean-field theory are taken into account. They find that the resulting strongly interacting system exhibits both interesting topological properties and spontaneous symmetry breaking.

Systematic derivation of realistic spin models for beyond-Heisenberg solids

Phys. Rev. B 101, 024418 (2020) - Published 21 January, 2020

The magnetic properties of many ultrathin films on metal substrates cannot be explained by the Heisenberg exchange interaction. Other known interactions, such as the biquadratic or the four-spin interaction, are also insufficient. This suggests the existence of further multispin interactions. The authors provide a systematic derivation of those interactions based on a multiband Hubbard model combined with a downfolding technique and propose a three-spin interaction. They show that it is strong in the systems with Fe on Ru(0001) and Fe on Rh(111), and even comparable in size to the Heisenberg interaction.

Spin-dimer ground state driven by consecutive charge and orbital ordering transitions in the anionic mixed-valence compound Rb4O6

Phys. Rev. B 101, 024419 (2020) - Published 22 January, 2020

A comprehensive study of the molecular mixed-valence compound Rb4O6 led the authors to the discovery of a peculiar π* orbital ordering transition of magnetic O2 anions within the charge ordered state, which promotes the formation of an orbital order-driven quantum spin state, composed of spin dimers. The experiments suggest that a delicate interplay between an electron-lattice coupling and Kugel-Khomskii-type superexchange in π-electron systems determines the magnetostructural properties. These results establish a fruitful analogy between π- and more conventional 3d-mixed-valence systems and push the research of such systems into new directions to tackle the intertwining of various active degrees of freedom.

In recent years, there has been a surge of interest in superconductivity in low-carrier-density materials, propelled by advances in experimental studies in systems such as SrTiO3. Here, the authors analyze how the superconducting transition temperature Tc varies in two dimensions as one tunes the Fermi energy EF with respect to Debye frequency ωD of a pairing boson. The authors work at weak coupling, by which they go beyond lowest order in the coupling and find the values of Tc with the exact prefactor.

Majorana modes are currently receiving a lot of attention, in part because they may be useful for quantum computation. One proposed platform to realize a large number of Majorana zero-energy modes involves flat bands at surfaces of superconductors lacking inversion symmetry. Here, the authors investigate what happens to these flat Majorana bands if interactions beyond BCS mean-field theory are taken into account. They find that the resulting strongly interacting system exhibits both interesting topological properties and spontaneous symmetry breaking.
