T/B scaling without quasiparticle mass divergence: YbCo2Ge4

Akito Sakai, Kentaro Kitagawa, Kazuyuki Matsubayashi, Makoto Iwatani, and Philipp Gegenwart

Phys. Rev. B 94, 041106(R) (2016) - Published 8 July, 2016

“Strange metal phases”, displaying strong deviations from Fermi liquid theory, are discussed in the context of cuprates, itinerant magnets, or heavy-fermion metals. Several Yb-based materials, e.g., β-YbAlB4 or the Au-Al-Yb quasicrystal, display T/B scaling of magnetic and thermodynamic properties. This has been taken as evidence for zero-field quantum criticality without requirement to fine-tune composition and pressure. However, it appears unlikely that materials are accidentally located at such a special point in multidimensional phase space. In this paper, the authors demonstrate by a thermodynamic study on the new Kondo lattice compound YbCo2Ge4 that T/B scaling and a divergence of the magnetic Grüneisen parameter can arise without a quasiparticle mass divergence and in the absence of zero-field quantum criticality. They discuss alternative scenarios for such strange metal behavior.

First-order density-wave-like transitions in surface-doped Na2IrO3

Kavita Mehlawat and Yogesh Singh

Phys. Rev. B 94, 041109(R) (2016) - Published 18 July, 2016

The Kitaev model is a toy model for S=12 moments on a honeycomb lattice, which interact via strongly bond-dependent Ising-like interactions. In real material candidates like Na2IrO3, small Heisenberg interactions are also present in addition to dominant Kitaev interactions. The doped Kitaev-Heisenberg model has been predicted to show unconventional superconductivity and spin or charge density wave, and bond-order instabilities. In this paper, the authors have succeeded in surface-doping Na2IrO3 crystals by argon plasma etching and in changing the conductivity by several orders of magnitude. The doped samples show several unusual transport behaviors, including first order spin or charge density wave-like transitions.

Efficient variational diagonalization of fully many-body localized Hamiltonians

Frank Pollmann, Vedika Khemani, J. Ignacio Cirac, and S. L. Sondhi

Phys. Rev. B 94, 041116(R) (2016) - Published 28 July, 2016

The phenomenon of many-body localization generalizes Anderson localization to interacting systems. Understanding this conceptually novel phenomenon requires a study of many-body eigenstates at finite energy densities. This is a very challenging task since the most efficient numerical methods such as, e.g., the density matrix renormalization group method, can only access the ground state and low lying excitations. In this work, the authors introduce a unitary tensor network based variational method that approximately finds all many-body eigenstates of fully localized Hamiltonians and scales polynomially with system size. The usefulness of their approach is demonstrated by considering the Heisenberg chain in a strongly disordered magnetic field.

Giant permanent dipole moment of two-dimensional excitons bound to a single stacking fault

Phys. Rev. B 94, 041201(R) (2016) - Published 25 July, 2016

Two-dimensional potentials are excellent test beds for the physics of interacting excitonic gases, but engineering highly homogeneous potentials can be challenging. In this work, the authors investigate excitons bound to a single 10-μm scale stacking fault, finding excitonic luminescence with unprecedented homogeneity. The authors further show that stacking-fault-bound excitons are mobile and have a giant permanent dipole moment by means of the magneto-Stark effect. These results indicate that stacking faults may be a promising platform to probe the many-body physics of interacting dipoles in an atomically smooth potential.

Electron diffraction by plasmon waves

F. J. García de Abajo, B. Barwick, and F. Carbone

Phys. Rev. B 94, 041404(R) (2016) - Published 11 July, 2016

The properties of an electron beam can be manipulated by electromagnetic fields in vacuum via the ponderomotive force. Such an interaction is also at the core of the Kapitza-Dirac effect, which describes the diffraction of electrons by an optical standing wave. Here, the authors predict a new type of interaction between electrons and the electromagnetic field, opening up new possibilities for the manipulation of electron beams. If surface plasmon polaritons are tailored to interfere forming a periodic field pattern, it becomes possible to diffract electrons from such near field. With the proper manipulation of the plasmonic fields, orbital angular momentum can be imparted to the electrons, and even the phase of their wave functions can be manipulated. An additional degree of freedom is provided by the possibility to tailor the spatial properties of the light and the materials supporting the surface plasmons. This arbitrary control can be extended to different substrates such as graphene or layered systems and may open up a viable route to create tunable phase plates for electron microscopes.

Trion formation in a two-dimensional hole-doped electron gas

G. G. Spink, P. López Ríos, N. D. Drummond, and R. J. Needs

Phys. Rev. B 94, 041410(R) (2016) - Published 22 July, 2016

The creation of electron-hole pairs by photoexcitation in quasi-two-dimensional semiconductor heterostructures has long provided one motivation for the study of a positive impurity immersed in an electron gas. Improved understanding of such systems is vital to realize the full potential of solar cells and optoelectronic transistors and memory devices. Collective, many-body phenomena dominate the behavior of the hole-in-electron-gas system at high carrier density, while excitonic species such as the exciton (a bound state of an electron and the hole) and the trion (a bound state formed from two electrons and the hole) emerge at low density. Confinement enhances the binding energy in quantum wells compared to bulk samples but, despite much experimental and theoretical work, the properties of excitons and trions are still uncertain. The authors perform diffusion Monte Carlo calculations of a single positive impurity immersed in a two-dimensional, paramagnetic electron gas at zero temperature using the Coulomb (1/r) potential. A gradual crossover from the collective, many-body behavior to the trion state is studied over a range of carrier densities and electron-hole mass ratios consistent with recent experiments in GaAs and CdTe quantum wells. Relaxation energies, electron-hole pair correlation functions, and electron-hole center-of-mass momentum densities are reported for these systems and may be used, for example, in density functional theory studies of optoelectronic devices.

Many-body localization and transition by density matrix renormalization group and exact diagonalization studies

S. P. Lim and D. N. Sheng

Phys. Rev. B 94, 045111 (2016) - Published 13 July, 2016

This paper focuses on developing a new algorithm (En-DMRG) for obtaining highly excited states of disordered and strongly interacting spin systems. This line of research is stimulated by the growing interest in understanding the many-body localized (MBL) state, which emerges in disordered interacting systems at high energy densities through a disorder-driven dynamic phase transition. By studying the one-dimensional Heisenberg spin chain (with up to 72 spins) in a random field, the authors demonstrate the accuracy of the method in obtaining energy eigenstates and the corresponding statistical results of the quantum system in the MBL phase. The method presented in this work has the potential to be applicable in a variety of quantum statistical physics problems, possibly including the MBL phase in higher dimensions.

Probing 5f-state configurations in URu2Si2 with U LIII-edge resonant x-ray emission spectroscopy

C. H. Booth, S. A. Medling, J. G. Tobin, R. E. Baumbach, E. D. Bauer, D. Sokaras, D. Nordlund, and T.-C. Weng

Phys. Rev. B 94, 045121 (2016) - Published 15 July, 2016

URu2Si2 undergoes a second-order phase transition at 17.5 K that has defied attempts to identify its order parameter despite a vast literature extending over the last 30 years. A wide variety of theories have been posed to explain this so-called “hidden order”, some with exotic ground states. An important dividing line between these theories is the character of the 5f orbital: on one side sit theories that require a localized f2 configuration (f-manifold crystalline electric field effects, hastatic order, etc.), while on the other sit those that start from an itinerant, partially occupied f3 orbital (band structure + hybridization). Unfortunately, the experimental measures remain muddy on this issue, with indications of both localized f2 and itinerant f3 behavior depending on the experiment. Here, the authors report U LIII-edge absorption/Lα1 emission resonant x-ray emission spectroscopy measurements comparing data from URu2Si2 to UCd11, UF4, and UO2 data to unravel the various roles of f-orbital occupation, delocalization, and ligand-field splitting of the d manifold. The data indicate a dominant delocalized f3 configuration that is likely partially occupied, with no measurable change in occupancy to temperatures as low as 10 K. While these measurements do not rule out a minority localized f2 configuration, any theory relying on such a configuration must account for its relatively small contribution to the Fermi surface.
