Superconductivity, pseudogap, and phase separation in topological flat bands

Johannes S. Hofmann, Erez Berg, and Debanjan Chowdhury

Phys. Rev. B 102, 201112(R) (2020) - Published 11 November, 2020

Can superconductivity exist even if the electron kinetic energy is completely quenched, as in a flat band? This is fundamentally a nonperturbative problem, since the interaction strength is the only relevant energy scale. Here, the authors study a two-dimensional model of an isolated Chern band at partial filling with local attractive interactions. Their quantum Monte Carlo calculations demonstrate unambiguously that the ground state is a superconductor, emerging from an incoherent Cooper-pair liquid at temperatures above a critical temperature. Strikingly, the latter scales almost linearly with the interaction strength.

Experimental observation of Dirac cones in artificial graphene lattices

Shaosheng Yue, Hui Zhou, Daiyu Geng, Zhenyu Sun, Masashi Arita, Kenya Shimada, Peng Cheng, Lan Chen, Sheng Meng, Kehui Wu, and Baojie Feng

Phys. Rev. B 102, 201401(R) (2020) - Published 9 November, 2020

Here, the authors synthesize macroscopic artificial graphene via self-assembly of C60 molecules on metal surfaces. The macroscopic scale of these systems enables direct investigation of their electronic structure by angle-resolved photoemission spectroscopy. The long-expected Dirac cones of artificial graphene at the K points of the Brillouin zone are directly observed. These results will stimulate ongoing efforts to fabricate molecular quantum devices based on artificial graphene.

Partial equilibration of anti-Pfaffian edge modes at ν=5/2

Hamed Asasi and Michael Mulligan

Phys. Rev. B 102, 205104 (2020) - Published 4 November, 2020

The recent thermal Hall conductance measurement of K2.5π2kBT/3h of the ν=5/2 quantum Hall state provides strong evidence for the realization of a topological ground state whose quasiparticles exhibit non-Abelian statistics. However, the precise identity of the state depends on the degree of edge-mode equilibration. Here, the authors show that in the limit of strong Coulomb interaction and approximate spin degeneracy, the anti-Pfaffian state admits low-temperature edge phases that exhibit fully equilibrated electrical transport coexisting with partially equilibrated thermal transport, consistent with current experimental measurements.

Efficient simulation of moiré materials using the density matrix renormalization group

Tomohiro Soejima (副島智大), Daniel E. Parker, Nick Bultinck, Johannes Hauschild, and Michael P. Zaletel

Phys. Rev. B 102, 205111 (2020) - Published 11 November, 2020

Despite considerable interest, it has been difficult to conclusively determine the ground state of twisted bilayer graphene (tBLG), due to the long-range nature of the Coulomb interaction and the fragile topology of the tBLG flat bands. This paper puts forward a method for studying tBLG more efficiently: mixed-xk space density-matrix renormalization group (DMRG) with matrix product operator (MPO) compression. The method enables the authors to calculate accurately the ground state of single-valley single-spin tBLG, and it puts DMRG with more degrees of freedom, such as valley, within reach.

Substrate screening approach for quasiparticle energies of two-dimensional interfaces with lattice mismatch

Chunhao Guo, Junqing Xu, Dario Rocca, and Yuan Ping

Phys. Rev. B 102, 205113 (2020) - Published 11 November, 2020

The authors develop an efficient and accurate interpolation technique for the matrix elements of dielectric matrices in the entire q + G reciprocal space between material and substrate.The method makes possible quasiparticle energy calculations within the GW approximation for arbitrarily mismatched interfaces, free of strain and symmetry constraints. This is extremely important for practical applications.

Higher-order non-Hermitian skin effect

Kohei Kawabata, Masatoshi Sato, and Ken Shiozaki

Phys. Rev. B 102, 205118 (2020) - Published 17 November, 2020

A unique feature of non-Hermitian systems is the skin effect, for which an extensive number of boundary modes appear in the presence of boundaries. Here, the authors discover higher-order counterparts of the non-Hermitian skin effect that exhibit new boundary physics. As a prime example, the second-order skin effect in two dimensions hosts corner skin modes induced by spatial symmetry protected non-Hermitian topology, which contrasts with both the conventional skin effect and Hermitian higher-order topological phases.

Noncommutative field theory and composite Fermi liquids in some quantum Hall systems

Zhihuan Dong and T. Senthil

Phys. Rev. B 102, 205126 (2020) - Published 20 November, 2020

This paper addresses long-standing fundamental questions on the validity of the classic Halperin-Lee-Read (HLR) theory, which is thought to describe metallic composite Fermi liquids in quantum Hall systems. The authors derive a novel “noncommutative” field theory as a low-energy description, and obtain the HLR action and its microscopic parameters in a further approximation. The work demonstrates the importance of noncommutative field theory for future microscopic studies of composite Fermi liquids in quantum Hall systems.

Strongly correlated multi-impurity models: The crossover from a single-impurity problem to lattice models

Fabian Eickhoff and Frithjof B. Anders

Phys. Rev. B 102, 205132 (2020) - Published 25 November, 2020

A mathematical criterion for the number of screening channels in multi-impurity Anderson models is given, dividing these models into two classes. As a consequence, the notion of independent single-ion Kondo effects can be ruled out as the mechanism for a collective singlet formation in heavy-fermion systems. Heavy Fermi liquid formation and its concomitant antiferromagnetic order are linked to an effective hopping between correlated orbitals, whereby the Mott-Hubbard transition in the correlated band provides a microscopic mechanism for the conjectured Lifshitz transition.

Phys. Rev. B 102, 205418 (2020) - Published 16 November, 2020

The interaction of light and magnetism at the nanoscale is a topic of fundamental interest with potential impact on future spintronics applications. This work addresses theoretically and experimentally the effect of femtosecond laser pulse excitation on the magnetic, structural, and chemical stability of individual magnetic cobalt nanoparticles, including the role of the substrate or matrix. Based on their results, the authors discuss possible pathways to achieve laser-induced magnetic switching in individual nanostructures.

The interaction of light and magnetism at the nanoscale is a topic of fundamental interest with potential impact on future spintronics applications. This work addresses theoretically and experimentally the effect of femtosecond laser pulse excitation on the magnetic, structural, and chemical stability of individual magnetic cobalt nanoparticles, including the role of the substrate or matrix. Based on their results, the authors discuss possible pathways to achieve laser-induced magnetic switching in individual nanostructures.
