Dynamical generation of topological masses in Dirac fermions

Yuan-Yao He, Xiao Yan Xu, Kai Sun, Fakher F. Assaad, Zi Yang Meng, and Zhong-Yi Lu

Phys. Rev. B 97, 081110(R) (2018) - Published 22 February, 2018

Using large-scale quantum Monte Carlo simulations, the authors unbiasedly demonstrate the existence of a topological Mott insulator – an interaction-driven topological insulator emerging from a strongly correlated Dirac semimetal. The model designed here consists of Dirac fermions and fluctuating Ising fields mediating interactions between fermions. By tuning the fluctuation strength of the Ising fields, the authors show the existence of a topological quantum phase transition between the topological Mott insulator phase and the Dirac-semimetal phase. Furthermore, the quantum critical point was found to be in the (2+1)D N=8 Chiral Ising universality class.

Inducing coherent quantum dot interactions

Eric W. Martin and Steven T. Cundiff

Phys. Rev. B 97, 081301(R) (2018) - Published 15 February, 2018

Semiconductor quantum dots (QDs) are typically entirely uncoupled, and interfacial QDs are no exception. However, exciting higher-energy quantum-well states can turn on QD interactions. Here, the authors measure individual QDs with a coherent spectroscopy that is extremely sensitive to interactions. They demonstrate an induced binding between two distinct QDs with a very weak excitation of delocalized quantum-well states. This interaction is presented as a possible method for turning on coupling between quantum states and for measuring fundamental processes in semiconductors with nanometer spatial resolution.

Size effects on supercooling phenomena in strongly correlated electron systems: IrTe2 and θ(BEDTTTF)2RbZn(SCN)4

H. Oike, M. Suda, M. Kamitani, A. Ueda, H. Mori, Y. Tokura, H. M. Yamamoto, and F. Kagawa

Phys. Rev. B 97, 085102 (2018) - Published 1 February, 2018

Sample miniaturization has been recognized to be helpful in obtaining deeply supercooled liquids or metastable crystalline solids. Here, the authors generalize the idea of the size effect with phenomenological simulations, and show that it certainly works in two distinct correlated electron systems. Because the validity of the size effects does not rely on microscopic details of each material, they are expected to be applicable to other correlated electron systems, potentially facilitating the creation of metastable electronic states.

Equivalence of restricted Boltzmann machines and tensor network states

Jing Chen, Song Cheng, Haidong Xie, Lei Wang, and Tao Xiang

Phys. Rev. B 97, 085104 (2018) - Published 2 February, 2018

The restricted Boltzmann machine is a fundamental building block of deep learning. The authors demonstrate its equivalence with tensor network states with explicit mappings, thus drawing a constructive connection between deep learning and quantum physics. On one side, deep learning approaches can be used to study novel states of matter. In return, investigations of tensor network states and their expressibility can be adapted to guide neural network architecture design.

Symmetry breaking and the fermionic fractional Chern insulator in topologically trivial bands

Stefanos Kourtis

Phys. Rev. B 97, 085108 (2018) - Published 5 February, 2018

Subjecting a topologically nontrivial class of noninteracting electronic states to interactions can sometimes yield a “fractional” topologically ordered version of that class. For example, electrons in topological bands with integer-quantized Hall conductivity can generate fractional quantum Hall (FQH) states upon addition of repulsive interactions. However, of all existing material band structures, the topologically nontrivial ones are rare. Here, the author demonstrates theoretically in a minimal setting how strong interactions and symmetry breaking can induce FQH-type topological order even in topologically trivial bands. This finding shows that even topologically trivial band structures – the vast majority – can host topological order.

Nonmonotonic magnetoresistance of a two-dimensional viscous electron-hole fluid in a confined geometry

P. S. Alekseev, A. P. Dmitriev, I. V. Gornyi, V. Yu. Kachorovskii, B. N. Narozhny, and M. Titov

Phys. Rev. B 97, 085109 (2018) - Published 5 February, 2018

The last few years have seen an explosion of interest in hydrodynamic effects in interacting electron systems in ultrapure materials, where the collective motion of charge carriers may resemble the flow of a viscous fluid. In a confined geometry, such as that provided by ultrahigh quality nanostructures, one expects the electronic fluid to exhibit Poiseuille-type flow profile. Here, the authors show that in two-component systems near charge neutrality the hydrodynamic viscous flow is strongly affected by the mutual friction and recombination between the two constituents leading to a strongly nonuniform current density and nonmonotonic magnetoresistance that happens to be negative (positive) in low (high) magnetic fields.

Experimental evidence for the microscopic mechanism of the unusual spin-induced electric polarization in GdMn2O5

G. Yahia, F. Damay, S. Chattopadhyay, V. Balédent, W. Peng, S. W. Kim, M. Greenblatt, M.-B. Lepetit, and P. Foury-Leylekian

Phys. Rev. B 97, 085128 (2018) - Published 15 February, 2018

The spin induced ferroelectricity of the RMn2O5 family is ascribed to an exchange-striction mechanism related to the frustrated Mn3+-Mn4+ antiferromagnetic interactions. From an accurate powder neutron diffraction experiment on an isotope-enriched sample of GdMn2O5, the authors detect in this compound a supplementary exchange-striction mechanism responsible for its exceptionally large electric polarization. This additional contribution comes from the release of the frustration between the huge and isotropic Gd3+ moments and the Mn3+/Mn4+ spins. The key ingredients to the atomic displacements are the isotropic Gd3+ electronic structure and the mediation of the Gd/Mn magnetic interactions by the oxygens. This results in a differential dependence of the Gd/Mn magnetic exchanges to the Mn-O distances and not the Gd-Mn ones, as predicted.

Electron-phonon coupling in graphene placed between magnetic Li and Si layers on cobalt

Dmitry Yu. Usachov, Alexander V. Fedorov, Oleg Yu. Vilkov, Ilya I. Ogorodnikov, Mikhail V. Kuznetsov, Alexander Grüneis, Clemens Laubschat, and Denis V. Vyalikh

Phys. Rev. B 97, 085132 (2018) - Published 21 February, 2018

Superconductivity in two-dimensional materials remains largely unexplored and attracts much attention. Although graphene is not a superconductor, adsorption of alkali metals on its surface may enhance electron-phonon coupling (EPC) sufficiently to induce superconductivity. Here, using photoemission spectroscopy, the authors study the electronic structure and EPC in a Li-doped graphene monolayer weakly bonded to a cobalt substrate. It is shown that EPC is high enough to create superconductivity in graphene, however the nonmagnetic graphene layer is clamped between two oppositely magnetized atomic layers. This condition makes the studied system a promising platform for understanding the influence of magnetic environment on superconductivity at low dimensions.

Localization enhanced and degraded topological order in interacting p-wave wires

G. Kells, N. Moran, and D. Meidan

Phys. Rev. B 97, 085425 (2018) - Published 20 February, 2018

Interest in quantum memory devices based on topological superconductors and their non-Abelian zero modes is motivated by the observation that at zero temperature the information stored in these devices is exponentially protected. In noninteracting systems, due to the fact that the system can be described using normal modes, much of this protection also exists at higher temperatures. The authors examine here how this picture gradually breaks down at higher temperatures when interactions are present, and explore the conjecture that the topological protection may be recovered by disorder-induced localization. They see that the disorder triggers multiple mechanisms which, depending on the parameters of the system, can both enhance and degrade the stability of the topological zero modes.

Interest in quantum memory devices based on topological superconductors and their non-Abelian zero modes is motivated by the observation that at zero temperature the information stored in these devices is exponentially protected. In noninteracting systems, due to the fact that the system can be described using normal modes, much of this protection also exists at higher temperatures. The authors examine here how this picture gradually breaks down at higher temperatures when interactions are present, and explore the conjecture that the topological protection may be recovered by disorder-induced localization. They see that the disorder triggers multiple mechanisms which, depending on the parameters of the system, can both enhance and degrade the stability of the topological zero modes.
