Thermal diffusivity above the Mott-Ioffe-Regel limit

Jiecheng Zhang, Erik D. Kountz, Eli M. Levenson-Falk, Dongjoon Song, Richard L. Greene, and Aharon Kapitulnik

Phys. Rev. B 100, 241114(R) (2019) - Published 24 December, 2019

Understanding transport of charge excitations in strongly correlated electron systems exhibiting the “strange metal” state without long-lived quasiparticle excitations has been a long-standing challenge in condensed matter physics. Here, the authors demonstrate that thermal diffusivity, which tracks energy-thermalization processes, exhibits a limiting Planckian relaxation time and a unique thermal diffusion velocity. These reflect both the contribution of phonons and electrons. This result is bound by the thermal diffusivity of the electrons at the Mott-Ioffe-Regel limit, where the mean-free-path reaches atomic distances.

Ordering phenomena of spin trimers accompanied by a large geometrical Hall effect

Shang Gao, Max Hirschberger, Oksana Zaharko, Taro Nakajima, Takashi Kurumaji, Akiko Kikkawa, Junichi Shiogai, Atsushi Tsukazaki, Shojiro Kimura, Satoshi Awaji, Yasujiro Taguchi, Taka-hisa Arima, and Yoshinori Tokura

Phys. Rev. B 100, 241115(R) (2019) - Published 27 December, 2019

Noncoplanar spin trimers are the basic units that define nonzero scalar spin chirality. They are the key ingredients to achieve the chirality-induced geometrical Hall effect. Here, through neutron diffraction, the authors reveal the emergence of noncoplanar Dy3+ spin-trimer units in metallic Dy3Ru4Al12. With a magnetic field, they can control the local spin chirality of the spin trimers as well as its ferroic/antiferroic order. In phases with nonzero total scalar spin chirality, a large geometrical Hall effect is observed. The study reveals that systems composed of tunable spin trimers can be a fertile field for the exploration of a large emergent electromagnetic response, arising from real-space topological magnetic order.

Evidence of charge density wave with anisotropic gap in a monolayer VTe2 film

Yuan Wang, Junhai Ren, Jiaheng Li, Yujia Wang, Huining Peng, Pu Yu, Wenhui Duan, and Shuyun Zhou

Phys. Rev. B 100, 241404(R) (2019) - Published 9 December, 2019

Angle-resolved photoemission spectroscopy measurements reveal the evidence of a charge density wave (CDW) and the underlying mechanism in a monolayer VTe2 film. The Fermi surface map is partially gapped and shows an arc shape. The CDW gap is found to be rather anisotropic and attributed to the imperfect nesting. First-principles calculations further indicate electron-phonon coupling at the corresponding wave vector. These observations suggest that both Fermi surface nesting and phonon instability contribute significantly to the CDW formation in this monolayer VTe2 film.

Observation of Kondo resonance in valence-ordered YbPd

Masanobu Shiga, Kengo Okimura, Hiroki Takata, Akihiro Mitsuda, Isao Maruyama, Hirofumi Wada, Yuji Inagaki, and Tatsuya Kawae

Phys. Rev. B 100, 245117 (2019) - Published 10 December, 2019

Generally, valence ordering is accompanied by a significant decrease in the carrier concentration, inhibiting the Kondo effect. YbPd exhibits valence ordering of two Yb valence states, Yb+2.6 and Yb+3, where the valence fluctuations survive even below the ordering temperature. Using a point-contact spectroscopy, the authors reveal here that the differential conductance spectra are reproduced by the sum of two Fano curves. These spectra provide evidence for the screening of the magnetic moments at the valence-ordering sites owing to the Kondo effect.

Matrix product state algorithms for Gaussian fermionic states

Norbert Schuch and Bela Bauer

Phys. Rev. B 100, 245121 (2019) - Published 12 December, 2019

Simulation methods for real materials often require the solution of extremely large inhomogeneous systems of noninteracting fermions. Here, the authors show how the density matrix renormalization group (DMRG), the most successful method for 1D interacting systems, can be adapted to noninteracting fermions, giving a significant improvement both over conventional DMRG and over the full solution of the noninteracting problem. The authors test the method on a range of one- and two-dimensional examples for both static and dynamic properties, demonstrating its applicability to systems up to a million sites.

Bosonization in three spatial dimensions and a 2-form gauge theory

Yu-An Chen and Anton Kapustin

Phys. Rev. B 100, 245127 (2019) - Published 16 December, 2019

The well-known Jordan-Wigner transformation maps an arbitrary system of fermions on a one-dimensional lattice to a system of spins. An essential property of this transformation is that it preserves the locality of observables. This transformation has been recently extended to two-dimensional lattices, where it maps an arbitrary system of fermions to a gauge theory, with locality preserved. Here, the authors construct a bosonization map for arbitrary systems of fermions in three dimensions. As an application, the authors design a model of interacting spins on a cubic lattice, which is exactly soluble and is equivalent to a tight-binding model of free fermions with Dirac points.

Role of correlations in determining the Van Hove strain in Sr2RuO4

Phys. Rev. B 100, 245139 (2019) - Published 23 December, 2019

Piezoelectric-based uniaxial pressure devices have become an important tool for investigating correlated electron systems. In Sr2RuO4, a Van Hove singularity can be tuned to the Fermi level, which more than doubles the superconducting critical temperature. With a new style of pressure device, the authors have measured here the stress at which this occurs with high accuracy, and the result now gives an unmistakable discrepancy with predictions from noninteracting electronic structure calculations. With this knowledge, they put constraints on the interaction parameters, improving our understanding of both the pressurized and ambient-pressure properties of Sr2RuO4.

Observation of nonequilibrium motion and equilibration in polariton rings

Phys. Rev. B 100, 245304 (2019) - Published 23 December, 2019

Recent progress in fabricating long-lifetime semiconductor microcavities has improved the thermalization of polaritons, quasiparticles arising from the strong coupling between photons and excitons in a microcavity. Here, the authors image nondestructively the real-time dynamics of the excited polaritons settling to the bottom of a tilted ring trap, which shows damped pendulum-like oscillations akin to atomic condensates in optical harmonic traps. Smoking gun evidence for extremely long transport lengths of the exciton reservoir is shown, which opens a new perspective for reservoir engineering.

Phys. Rev. B 100, 245401 (2019) - Published 2 December, 2019

Surface acoustic waves (SAWs) can transport single electrons over distances of many microns. By transporting single electrons into a hole reservoir, SAWs may produce a stream of single photons, with potential applications in quantum communications and quantum computing. The authors create a lateral p−n junction in an undoped GaAs/AlGaAs heterostructure, using SAWs to transport single electrons between regions of induced electrons. They also pump electrons into a region of induced holes and observe light emission from such a lateral p−n junction.

Piezoelectric-based uniaxial pressure devices have become an important tool for investigating correlated electron systems. In Sr2RuO4, a Van Hove singularity can be tuned to the Fermi level, which more than doubles the superconducting critical temperature. With a new style of pressure device, the authors have measured here the stress at which this occurs with high accuracy, and the result now gives an unmistakable discrepancy with predictions from noninteracting electronic structure calculations. With this knowledge, they put constraints on the interaction parameters, improving our understanding of both the pressurized and ambient-pressure properties of Sr2RuO4.

Recent progress in fabricating long-lifetime semiconductor microcavities has improved the thermalization of polaritons, quasiparticles arising from the strong coupling between photons and excitons in a microcavity. Here, the authors image nondestructively the real-time dynamics of the excited polaritons settling to the bottom of a tilted ring trap, which shows damped pendulum-like oscillations akin to atomic condensates in optical harmonic traps. Smoking gun evidence for extremely long transport lengths of the exciton reservoir is shown, which opens a new perspective for reservoir engineering.

Surface acoustic waves (SAWs) can transport single electrons over distances of many microns. By transporting single electrons into a hole reservoir, SAWs may produce a stream of single photons, with potential applications in quantum communications and quantum computing. The authors create a lateral p−n junction in an undoped GaAs/AlGaAs heterostructure, using SAWs to transport single electrons between regions of induced electrons. They also pump electrons into a region of induced holes and observe light emission from such a lateral p−n junction.
