EDITORS' SUGGESTION

Unusual pressure-induced metallic state in the correlated narrow band-gap semiconductor FeSi

G. R. Hearne, P. Musyimi, S. Bhattacharjee, M. K. Forthaus, and M. M. Abd-Elmeguid

Phys. Rev. B 100, 155118 (2019) - Published 10 October, 2019

The extent of electron correlations in FeSi and Fe-3 $d$ /Si-3 $p$ hybridization embeds a narrow gap in the resultant quasiparticle peak at the Fermi level. Here, the authors investigate the effect of compression tuning of this electronic fine structure and demonstrate its sensitivity to lattice heterogeneities, e.g., those resulting from extrinsic lattice strains. Pressurization tunes the mobility edge relative to the Fermi level until an unusual metallic state ensues beyond about 15 GPa, which does not involve any structural instability of the original $B$ 20-type cubic structure.

EDITORS' SUGGESTION

Magnetoelectric spectroscopy of spin excitations in ${LiCoPO}_{4}$

V. Kocsis, S. Bordács, Y. Tokunaga, J. Viirok, L. Peedu, T. Rõõm, U. Nagel, Y. Taguchi, Y. Tokura, and I. Kézsmárki

Phys. Rev. B 100, 155124 (2019) - Published 14 October, 2019

Magnetoelectric spectroscopy is a powerful tool to determine all off-diagonal elements of the magnetoelectric tensor in a contactless fashion. Here, the authors demonstrate the efficiency of this optical method by measuring the off-diagonal magnetoelectric response of LiCoPO $_{4}$ in the GHz-THz regime. They find that the magnetoelectric effect in this antiferromagnet is dominated by the symmetric (quadrupolar) part of the magnetoelectric tensor.

EDITORS' SUGGESTION

Entropy-cooled nonequilibrium states of the Hubbard model

Philipp Werner, Jianju Li, Denis Golež, and Martin Eckstein

Phys. Rev. B 100, 155130 (2019) - Published 16 October, 2019

An entropy cooling scheme based on electron or hole evaporation into full or empty narrow bands is used to prepare several interesting nonequilibrium states of the Hubbard model: (i) cold photo-doped Mott insulating states with long-lived quasiparticles, (ii) superconducting states in the repulsive model with an inverted population, and (iii) η-paired states in systems with a large density of doublons and holons.

EDITORS' SUGGESTION

Single-parameter scaling in the magnetoresistance of optimally doped ${La}_{2 - x} {Sr}_{x} {CuO}_{4}$

Christian Boyd and Philip W. Phillips

Phys. Rev. B 100, 155139 (2019) - Published 25 October, 2019

Single-parameter scaling is a heralded consequence of criticality. In magnetotransport, however, the electron mobility typically couples to magnetic field and produces a form of single-parameter scaling in noncritical systems. Here, the authors examine recent magnetoresistance data on thin film La $_{2 - x}$ Sr $_{x}$ CuO $_{4}$ and find that, unlike the case of the quantum critical iron superconductors, single-parameter scaling ceases in conjunction with the breakdown of a classical disorder description for the magnetoresistance at the lowest temperatures. This call into question the relationship between material inhomogeneity and critical scaling in cuprates.

EDITORS' SUGGESTION

Multifaceted machine learning of competing orders in disordered interacting systems

Michael Matty, Yi Zhang, Zlatko Papić, and Eun-Ah Kim

Phys. Rev. B 100, 155141 (2019) - Published 28 October, 2019

There are growing efforts to use artificial neural networks (ANNs) for phase recognition. The authors target the problem of competition between topological order and broken symmetry states in the presence of disorder. The lack of traditional diagnostics for this problem makes any progress using ANNs particularly significant. The authors successfully obtain a phase diagram consisting of fractional quantum Hall, charge density wave, and localized phases using multifaceted inputs that inform defining traits of these phases to the ANN.

EDITORS' SUGGESTION

Gauging fractons: Immobile non-Abelian quasiparticles, fractals, and position-dependent degeneracies

Daniel Bulmash and Maissam Barkeshli

Phys. Rev. B 100, 155146 (2019) - Published 29 October, 2019

Fracton phases of matter contain quasiparticles that are constrained, not by energetics but by the structure of local operators, to move along lower dimensional submanifolds. Here, the authors present a very general scheme for producing exactly solvable, non-Abelian fracton models by gauging symmetries that permute fractons, exploring several examples in detail. One of the resulting models contains immobile, non-Abelian quasiparticles that can only be created at the corners of operators with fractal support.

EDITORS' SUGGESTION

Surface structure and stacking of the commensurate $(\sqrt{13} \times \sqrt{13}) R 13 . 9^{\circ}$ charge density wave phase of $1 T - {TaS}_{2} (0001)$

Gevin von Witte, Tilman Kißlinger, Jan Gerrit Horstmann, Kai Rossnagel, M. Alexander Schneider, Claus Ropers, and Lutz Hammer

Phys. Rev. B 100, 155407 (2019) - Published 8 October, 2019

Layered materials forming charge-density-wave (CDW) states exhibit an intriguing interplay between crystallographic structure and electronic properties. Using quantitative low-energy electron diffraction, the authors determine with picometer accuracy the complex surface structure of the transition-metal dichalcogenide 1 $T$ -TaS $_{2}$ in its commensurate CDW phase. The key findings are the vertical CDW stacking between first and second trilayer and the broken inversion symmetry in the first S-Ta-S trilayer, due to an expansion of the topmost S layer.
