Frustrated Kondo impurity triangle: A simple model of deconfinement

Elio J. König, Piers Coleman, and Yashar Komijani

Phys. Rev. B 104, 115103 (2021) - Published 3 September, 2021

Concepts of topological order are central to our understanding of strongly correlated quantum materials. In this work, the authors propose that such concepts – which transcend the Landau paradigm – also appear in frustrated impurity models. In particular, they show that a variety of defining characteristics of topological order appear in a frustrated Kondo triangle: an irrational ground-state degeneracy reminiscent of anyons, ordering of a Wilson-loop-like order parameter, and a phase transition driven by the proliferation of monopoles of an emergent gauge field.

Differentiating Hund from Mott physics in a three-band Hubbard-Hund model: Temperature dependence of spectral, transport, and thermodynamic properties

K. M. Stadler, G. Kotliar, S.-S. B. Lee, A. Weichselbaum, and J. von Delft

Phys. Rev. B 104, 115107 (2021) - Published 7 September, 2021

For many years, strong electronic correlations in metals have mainly been associated with ‘Mottness’ driven by the Coulomb repulsion, which suppresses charge fluctuations. Recently, ‘Hundness’, induced by Hund’s rule coupling that affects spin dynamics, has gained recognition as another route to strong correlations. Using dynamical mean-field theory and the numerical renormalization group, the authors identify numerous fingerprints distinguishing Hundness from Mottness in the temperature dependence of various physical quantities for a minimal model of Hund metals.

Mapping out the emergence of topological features in the highly alloyed topological Kondo insulators Sm1xMxB6(M=Eu,Ce)

Yishuai Xu, Erica C. Kotta, M. S. Song, B. Y. Kang, J. W. Lee, B. K. Cho, Shouzheng Liu, Turgut Yilmaz, Elio Vescovo, Jonathan D. Denlinger, Lin Miao, and L. Andrew Wray

Phys. Rev. B 104, 115118 (2021) - Published 9 September, 2021

SmB6 is a strongly correlated material that has been considered as a topological insulator and a Kondo insulator. Here, the authors use angle-resolved photoemission spectroscopy to chart the evolution of topologically linked electronic structure features versus doping in Sm1xMxB6 (M=Eu, Ce). Topological band coherence phenomena are observed out to remarkably high alloy compositions (30% Eu and 50% Ce). Combined with numerical modeling, these results suggest that the topological surface-state spectral feature is protected by a hybridization gap much larger than the insulating gap.

Topological Goldstone phases of matter

Dominic V. Else

Phys. Rev. B 104, 115129 (2021) - Published 16 September, 2021

The author gives a general theory of the circumstances, in which Goldstone modes associated with spontaneous symmetry breaking can be “topologically nontrivial” in the sense, for example, that topological defects, such as skyrmions, carry nontrivial quantum numbers. The core physical idea is that such defects can always be mapped to nontrivial configurations of a background gauge field for the residual symmetry, such as fluxes and monopoles.

Optical control protocols for high-fidelity spin rotations of single SiV and SnV centers in diamond

Evangelia Takou and Sophia E. Economou

Phys. Rev. B 104, 115302 (2021) - Published 2 September, 2021

Group-IV defects in diamond are attractive qubit candidates that can be controlled optically. However, they have multiple excited states, leading to unwanted off-resonant transitions, which induce errors that lower the fidelity of quantum gate operations. Here, the authors design high-fidelity gate protocols that are tailored to these defects. Based on laser polarization tuning and pulse shaping, the proposed schemes counteract the errors and ensure high-fidelity operations.

Spectroscopy of the local density of states in nanowires using integrated quantum dots

Frederick S. Thomas, Malin Nilsson, Carlo Ciaccia, Christian Jünger, Francesca Rossi, Valentina Zannier, Lucia Sorba, Andreas Baumgartner, and Christian Schönenberger

Phys. Rev. B 104, 115415 (2021) - Published 15 September, 2021

The high control in the growth of single-crystalline semiconducting nanowires enables the integration of a single quantum dot (QD) by axial heteroepitaxy. These QDs have highly desired properties: electrically stable eigenstates with a large confinement and clean one-dimensional leads (L1 and L2) that connect the zero-dimensional QD with the two Fermi reservoirs. However, the one-dimensional nature of the leads causes a modulation in the density of states at each side of the QD. A procedure is introduced that allows to distinguish these lead features from excited states in the QD.

Current shot noise in atomic contacts: Fe and FeH2 between Au electrodes

Michael Mohr, Alexander Weismann, Dongzhe Li, Mads Brandbyge, and Richard Berndt

Phys. Rev. B 104, 115431 (2021) - Published 28 September, 2021

The shot noise of the current through an iron atom on gold and through FeH2 is measured and calculated. The authors find hydrogen to substantially increase the spin polarization up to values of about 80%. The data suggest that the quantum motion of hydrogen and the associated zero-point energy, which are not described by the density functional theory modeling here, may play an important role.

Strong magnetoresistance in a graphene Corbino disk at low magnetic fields

Masahiro Kamada, Vanessa Gall, Jayanta Sarkar, Manohar Kumar, Antti Laitinen, Igor Gornyi, and Pertti Hakonen

Phys. Rev. B 104, 115432 (2021) - Published 29 September, 2021

In the Hall bar geometry, both the transverse and longitudinal bulk conductivities – σxy(B) and σxx(B), respectively – determine the resistivity ρxx(B). Consequently, magnetoresistance R(B) becomes independent of the applied magnetic field B in the simplest one-band model. In the corresponding Corbino-ring setting, σxy drops out and the resistivity is obtained as ρxx(B)=1/σxx(B). Strong, pure B2 magnetoresistance is observed in the reported experimental work and used to extract information about scattering mechanisms in graphene, which amply demonstrates the usefulness of the Corbino-ring geometry for transport studies of 2D materials.

Group-IV defects in diamond are attractive qubit candidates that can be controlled optically. However, they have multiple excited states, leading to unwanted off-resonant transitions, which induce errors that lower the fidelity of quantum gate operations. Here, the authors design high-fidelity gate protocols that are tailored to these defects. Based on laser polarization tuning and pulse shaping, the proposed schemes counteract the errors and ensure high-fidelity operations.

The high control in the growth of single-crystalline semiconducting nanowires enables the integration of a single quantum dot (QD) by axial heteroepitaxy. These QDs have highly desired properties: electrically stable eigenstates with a large confinement and clean one-dimensional leads (L1 and L2) that connect the zero-dimensional QD with the two Fermi reservoirs. However, the one-dimensional nature of the leads causes a modulation in the density of states at each side of the QD. A procedure is introduced that allows to distinguish these lead features from excited states in the QD.

The shot noise of the current through an iron atom on gold and through FeH2 is measured and calculated. The authors find hydrogen to substantially increase the spin polarization up to values of about 80%. The data suggest that the quantum motion of hydrogen and the associated zero-point energy, which are not described by the density functional theory modeling here, may play an important role.

Strong magnetoresistance in a graphene Corbino disk at low magnetic fields

Phys. Rev. B 104, 115432 (2021) - Published 29 September, 2021

In the Hall bar geometry, both the transverse and longitudinal bulk conductivities – σxy(B) and σxx(B), respectively – determine the resistivity ρxx(B). Consequently, magnetoresistance R(B) becomes independent of the applied magnetic field B in the simplest one-band model. In the corresponding Corbino-ring setting, σxy drops out and the resistivity is obtained as ρxx(B)=1/σxx(B). Strong, pure B2 magnetoresistance is observed in the reported experimental work and used to extract information about scattering mechanisms in graphene, which amply demonstrates the usefulness of the Corbino-ring geometry for transport studies of 2D materials.
