Chiral topological phases from artificial neural networks

Raphael Kaubruegger, Lorenzo Pastori, and Jan Carl Budich

Phys. Rev. B 97, 195136 (2018) - Published 18 May, 2018

Artificial neural networks and machine learning tools have become ubiquitous far beyond the field of computer science. They already smartly assist us in our daily lives in various ways. Recently, these concepts have been adopted and applied in the realm of quantum physics, for example as a computational Ansatz for the state of a quantum many-body system. In this work, the authors harness the enormous flexibility of artificial neural networks to study exotic phases of quantum matter, known as chiral topological phases, that are particularly hard to investigate microscopically with more conventional computational methods.

Full dyon excitation spectrum in extended Levin-Wen models

Yuting Hu, Nathan Geer, and Yong-Shi Wu

Phys. Rev. B 97, 195154 (2018) - Published 29 May, 2018

The Levin‐Wen models are discrete gauge models, leading to intrinsic two-dimensional topological order. To incorporate the charge degrees of freedom at vertices for excited states, the authors propose to extend the Levin-Wen model by adding on one of the edges of each vertex a tail, labeled by its string type. They show that the local operators associated with the dyonic excitations obey the so‐called tube algebra. When the input data is associated with a finite or quantum group, any dyon species is described by three quantum numbers: charge, fluxon type, and twist.

Two-color Fermi-liquid theory for transport through a multilevel Kondo impurity

D. B. Karki, Christophe Mora, Jan von Delft, and Mikhail N. Kiselev

Phys. Rev. B 97, 195403 (2018) - Published 2 May, 2018

A multiorbital quantum impurity with effective spin S>1/2 connected to several reservoirs of conduction electrons can lead to a Kondo effect, exhibiting multistage screening. The ground state of a prototypical nanoscale device consisting of an S=1 quantum impurity connected to two conducting reservoirs is a spin singlet, formed via a two-stage Kondo screening mechanism. Understanding the equilibrium and nonequilibrium properties of the strong-coupling regime resulting from this two-stage screening has been an open problem for many years. Here, the authors offer a detailed description in terms of an effective local two-color Fermi liquid theory.

Optical properties of silicene, Si/Ag(111), and Si/Ag(110)

C. Hogan, O. Pulci, P. Gori, F. Bechstedt, D. S. Martin, E. E. Barritt, A. Curcella, G. Prevot, and Y. Borensztein

Phys. Rev. B 97, 195407 (2018) - Published 7 May, 2018

Silver is a popular choice of substrate for the growth of nanostructured 1D and 2D silicon – possibly silicenelike – layers. First-principles simulations and measurements of reflectance anisotropy and surface differential reflectivity spectroscopy are applied to the study of single monolayer Si/Ag(111) and Si/Ag(110) interfaces. The authors demonstrate the absence of structural and electronic properties of freestanding, graphenelike silicene, finding evidence for strong Si-Ag bonding in the Si/Ag(111) case and the formation of pentagonal nanoribbons on Si/Ag(110). Many-body effects in the optical response of silicene are found to cancel out.

Electron and Cooper-pair transport across a single magnetic molecule explored with a scanning tunneling microscope

J. Brand, S. Gozdzik, N. Néel, J. L. Lado, J. Fernández-Rossier, and J. Kröger

Phys. Rev. B 97, 195429 (2018) - Published 17 May, 2018

The interplay of magnetism and superconductivity gives rise to the emergence of various interesting phenomena in condensed matter physics, such as the Yu-Shiba-Rusinov in-gap modes created by local magnetic moments in superconducting hosts. Using normal-metal and superconducting tips the authors have formed contacts to an individual magnetic molecule adsorbed on a conventional superconductor. Spectroscopy of the differential conductance with tunable junction transparency has unveiled the crossover from quasiparticle tunneling, which probes the Bardeen-Cooper-Schrieffer energy gap as well as the Yu-Shiba-Rusinov levels, to the contact range where multiple Andreev reflection takes over.

Localized interlayer complexes in heterobilayer transition metal dichalcogenides

M. Danovich, D. A. Ruiz-Tijerina, R. J. Hunt, M. Szyniszewski, N. D. Drummond, and V. I. Fal'ko

Phys. Rev. B 97, 195452 (2018) - Published 31 May, 2018

Here, a prediction is made that, in the presence of donor impurities, the optical properties of type-II transition-metal dichalcogenide (TMD) heterobilayers are dominated by interlayer excitonic complexes bound to the impurity centers. Quantum Monte Carlo calculations reveal the stability of many such complexes, including neutral-donor bound excitons and biexcitons. A theory is developed for radiative decay of such complexes, where the localized nature of these few-carrier states allows recombination even for a finite misalignment between the TMD layers. A multipeak photoluminescence spectrum is predicted, in the energy range where recent experiments have observed broad luminescence peaks. These results provide a new perspective for interpreting the experimental observations, which so far have been attributed only to delocalized interlayer excitons.

It is a central goal of physics to characterize and classify quantum phases of matter, and it is by now well appreciated that both symmetry and entanglement play important role in understanding quantum phases. In past years, significant progress has been made in classifying 2D gapped phases featuring interesting interplay between long-range entanglement and symmetries. This paper is one of the first systematic studies of 3D gapless systems, where the interplay between entanglement and symmetry gives rise to interesting physics. This is an important step towards a more comprehensive understanding of the structure of quantum phases in general. Moreover, the classification scheme used here is based on direct and physical characterizations of the system, rather than formal abstract mathematics. This physics-based method can also be generalized to other systems. This way of thinking will pave the way to achieve a better understanding of the physical properties of exotic phases of matter.

Phys. Rev. B 97, 195403 (2018) - Published 2 May, 2018

A multiorbital quantum impurity with effective spin S>1/2 connected to several reservoirs of conduction electrons can lead to a Kondo effect, exhibiting multistage screening. The ground state of a prototypical nanoscale device consisting of an S=1 quantum impurity connected to two conducting reservoirs is a spin singlet, formed via a two-stage Kondo screening mechanism. Understanding the equilibrium and nonequilibrium properties of the strong-coupling regime resulting from this two-stage screening has been an open problem for many years. Here, the authors offer a detailed description in terms of an effective local two-color Fermi liquid theory.

Silver is a popular choice of substrate for the growth of nanostructured 1D and 2D silicon – possibly silicenelike – layers. First-principles simulations and measurements of reflectance anisotropy and surface differential reflectivity spectroscopy are applied to the study of single monolayer Si/Ag(111) and Si/Ag(110) interfaces. The authors demonstrate the absence of structural and electronic properties of freestanding, graphenelike silicene, finding evidence for strong Si-Ag bonding in the Si/Ag(111) case and the formation of pentagonal nanoribbons on Si/Ag(110). Many-body effects in the optical response of silicene are found to cancel out.

The interplay of magnetism and superconductivity gives rise to the emergence of various interesting phenomena in condensed matter physics, such as the Yu-Shiba-Rusinov in-gap modes created by local magnetic moments in superconducting hosts. Using normal-metal and superconducting tips the authors have formed contacts to an individual magnetic molecule adsorbed on a conventional superconductor. Spectroscopy of the differential conductance with tunable junction transparency has unveiled the crossover from quasiparticle tunneling, which probes the Bardeen-Cooper-Schrieffer energy gap as well as the Yu-Shiba-Rusinov levels, to the contact range where multiple Andreev reflection takes over.

Here, a prediction is made that, in the presence of donor impurities, the optical properties of type-II transition-metal dichalcogenide (TMD) heterobilayers are dominated by interlayer excitonic complexes bound to the impurity centers. Quantum Monte Carlo calculations reveal the stability of many such complexes, including neutral-donor bound excitons and biexcitons. A theory is developed for radiative decay of such complexes, where the localized nature of these few-carrier states allows recombination even for a finite misalignment between the TMD layers. A multipeak photoluminescence spectrum is predicted, in the energy range where recent experiments have observed broad luminescence peaks. These results provide a new perspective for interpreting the experimental observations, which so far have been attributed only to delocalized interlayer excitons.
