Multiple topological transitions in twisted bilayer graphene near the first magic angle

Kasra Hejazi, Chunxiao Liu, Hassan Shapourian, Xiao Chen, and Leon Balents

Phys. Rev. B 99, 035111 (2019) - Published 7 January, 2019

The noninteracting physics of electrons in twisted bilayer graphene is considered by varying the twist angle close to the magic angle using a continuum model. The magic angle is known to occur when the dispersion at the two Dirac cones of the two bands close to neutrality become quadratic. These are topological transitions, in which three moving Dirac points pass through each of the two immobile ones as the angle varies. Indeed, the motion of Dirac points is not limited to this and their participation in several topological transitions is very rich, which is the main subject of this study.

Detailed band structure of twinned and detwinned BaFe2As2 studied with angle-resolved photoemission spectroscopy

H. Pfau, C. R. Rotundu, J. C. Palmstrom, S. D. Chen, M. Hashimoto, D. Lu, A. F. Kemper, I. R. Fisher, and Z.-X. Shen

Phys. Rev. B 99, 035118 (2019) - Published 9 January, 2019

The superconducting dome of most iron-based superconductors emerges from a phase with nematic and magnetic ordering. However, the multiband and multiorbital nature of iron-based superconductors as well as twinning effects pose challenges to fully characterize the implications of these two ordering phenomena for the band structure. Here, the authors report high-quality ARPES measurements on twinned and detwinned BaFe2As2 and present a comprehensive and systematic overview of the band structure in the normal and the magnetically ordered states of this prototype parent compound.

Topological nodal-line semimetals in ferromagnetic rare-earth-metal monohalides

Simin Nie, Hongming Weng, and Fritz B. Prinz

Phys. Rev. B 99, 035125 (2019) - Published 14 January, 2019

The topological nodal-line semimetals (TNLSs) found so far are extremely limited to nonmagnetic materials and most of them are spinless. Here, the authors find from first-principles calculations and an effective model analysis that the single-layer rare-earth monohalides LaX and single-layer GdX (where X is Cl or Br) are ideal 2D Weyl semimetals and large-gap 2D quantum anomalous Hall insulators (QAHIs), respectively. Moreover, 3D LaX and 3D GdX are TNLSs and 3D weak QAHIs, respectively. The nodal lines in 3D LaX are robust against strong spin-orbit coupling, providing a novel platform toward exploring the exotic properties in nodal-line fermions.

NMR relaxation in Ising spin chains

Phys. Rev. B 99, 035156 (2019) - Published 29 January, 2019

The quantum Ising chain in a transverse magnetic field is the paradigm of a quantum phase transition, displaying universal quantum criticality at low temperatures. Insights from this model have informed studies of quantum criticality in numerous modern correlated-electron materials. There have been a number of experimental studies of the quantum Ising chain, most notably in the material CoNb2O6. It has recently become clear that there was a surprising discrepancy between the observations: the energy gap in the quantum disordered regime as measured by nuclear magnetic resonance was approximately twice that measured by other methods. Here, the authors show via careful analysis of the low-temperature excitations that this is not a discrepancy, rather, it is in fact to be expected from the subtle interactions between the excitations. Although the underlying spin excitations are bosonic, their interactions transmute them into fermions, and this is a key ingredient in understanding the experiments.

Charge fluctuations of a Cr atom probed in the optical spectra of a quantum dot

L. Besombes, H. Boukari, V. Tiwari, A. Lafuente-Sampietro, M. Sunaga, K. Makita, and S. Kuroda

Phys. Rev. B 99, 035309 (2019) - Published 24 January, 2019

Doping semiconductor quantum dots with a low density of transition elements allows us to optically probe and control spins of individual magnetic atoms. A large variety of magnetic elements can be incorporated in semiconductors, offering a large choice of localized spins. For some of these elements, optical excitation or electrical doping can change the d shell configuration and the oxidation state. This is the case for Cr in ZnTe, having both its donor and acceptor levels within the band gap of the host. Here, the authors show that the charge fluctuations of a Cr atom located close to a CdTe quantum dot in the ZnTe barrier can be detected optically. Fluctuations of the electric field produced by the three possible charge states (-e, 0, and +e) of the Cr atom are observed in magneto-optic and photon correlation measurements and can be modified by an applied bias voltage.

Nature of the excited states of layered systems and molecular excimers: Exciplex states and their dependence on structure

Marie-Christin Heissenbüttel, Philipp Marauhn, Thorsten Deilmann, Peter Krüger, and Michael Rohlfing

Phys. Rev. B 99, 035425 (2019) - Published 15 January, 2019

Chemically inert objects (e.g., noble-gas atoms) can show covalent-like excimer bonding when excited electronically. Analogous exciplex states are observed in layered materials such as graphite or transition-metal dichalcogenides. Here, the authors show by ab initio many-body perturbation theory that such exciplex states result from a delicate balance between on-site (or intralayer) and charge-transfer (or interlayer) electron-hole configurations. Both molecular systems and layered materials exhibit a characteristic relationship between geometric structure and excitation energetics.

Interlayer excitons in bilayer MoS2 with strong oscillator strength up to room temperature

Phys. Rev. B 99, 035443 (2019) - Published 31 January, 2019

Transition metal dichalcogenides are semiconducting materials in which optical properties are governed by Coulomb-bound electron-hole pairs, called excitons. Here, the authors investigate the different excitonic properties of monolayer, bilayer, and trilayer MoS2, revealing the existence of interlayer excitons in the last two cases. The paper presents both theoretical and experimental studies. DFT calculations of absorption are underpinned by reflectivity measurements, at temperatures from 4 to 300 K, on high-quality samples encapsulated in hexagonal boron nitride (hBN).

Doping semiconductor quantum dots with a low density of transition elements allows us to optically probe and control spins of individual magnetic atoms. A large variety of magnetic elements can be incorporated in semiconductors, offering a large choice of localized spins. For some of these elements, optical excitation or electrical doping can change the d shell configuration and the oxidation state. This is the case for Cr in ZnTe, having both its donor and acceptor levels within the band gap of the host. Here, the authors show that the charge fluctuations of a Cr atom located close to a CdTe quantum dot in the ZnTe barrier can be detected optically. Fluctuations of the electric field produced by the three possible charge states (-e, 0, and +e) of the Cr atom are observed in magneto-optic and photon correlation measurements and can be modified by an applied bias voltage.

Chemically inert objects (e.g., noble-gas atoms) can show covalent-like excimer bonding when excited electronically. Analogous exciplex states are observed in layered materials such as graphite or transition-metal dichalcogenides. Here, the authors show by ab initio many-body perturbation theory that such exciplex states result from a delicate balance between on-site (or intralayer) and charge-transfer (or interlayer) electron-hole configurations. Both molecular systems and layered materials exhibit a characteristic relationship between geometric structure and excitation energetics.

Transition metal dichalcogenides are semiconducting materials in which optical properties are governed by Coulomb-bound electron-hole pairs, called excitons. Here, the authors investigate the different excitonic properties of monolayer, bilayer, and trilayer MoS2, revealing the existence of interlayer excitons in the last two cases. The paper presents both theoretical and experimental studies. DFT calculations of absorption are underpinned by reflectivity measurements, at temperatures from 4 to 300 K, on high-quality samples encapsulated in hexagonal boron nitride (hBN).
