Theory of parametrically amplified electron-phonon superconductivity
10.1103/PhysRevB.96.014512 2017-07-19 Ultrafast optical manipulation of ordered phases in strongly correlated materials is a topic of significant theoretical, experimental, and technological interest. Inspired by a recent experiment on light-induced superconductivity in fullerenes [M. Mitrano et ... |

Driving induced many-body localization
10.1103/PhysRevB.96.020201 2017-07-19 Subjecting a many-body localized system to a time-periodic drive generically leads to delocalization and a transition to ergodic behavior if the drive is sufficiently strong or of sufficiently low frequency. Here we show that a specific drive can have an oppo... |

Dependence of the structure and dynamics of liquid silicon on the choice of density functional approximation
10.1103/PhysRevB.96.024203 2017-07-19 In addition to its technological relevance, silicon poses a challenge for first principles simulations because it undergoes a semiconductor-to-metal transition upon melting. Moreover, the resulting metallic liquid contains a mixture of metallic and covalent b... |

Magnetoelectric effect in doped magnetic ferroelectrics
10.1103/PhysRevB.96.024204 2017-07-19 We propose a model of magnetoelectric effect in doped magnetic ferroelectrics. This magnetoelectric effect does not involve the spin-orbit coupling and is based purely on the Coulomb interaction. We calculate magnetic phase diagram of doped magnetic ferroelec... |

Magnetic Möbius stripe without frustration: Noncollinear metastable states
10.1103/PhysRevB.96.024426 2017-07-19 The recently introduced area of topological magnetism searches for equilibrium structures stabilized by a combination of interactions and specific boundary conditions. Until now, the internal energy of open magnetic chains has been explored. Here, we study th... |

Time-domain stability of parametric synchronization in a spin-torque nano-oscillator based on a magnetic tunnel junction
10.1103/PhysRevB.96.024427 2017-07-19 We report on time-domain stability of the parametric synchronization in a spin-torque nano-oscillator (STNO) based on a magnetic tunnel junction. Time-domain measurements of the instantaneous frequency (fi) of a parametrically synchronized STNO show random sh... |

Electronic structure ofRSb(R=Y, Ce, Gd, Dy, Ho, Tm, Lu) studied by angle-resolved photoemission spectroscopy
10.1103/PhysRevB.96.035134 2017-07-19 We use high-resolution angle-resolved photoemission spectroscopy (ARPES) and electronic structure calculations to study the electronic properties of rare-earth monoantimonides RSb (R = Y, Ce, Gd, Dy, Ho, Tm, Lu). The experimentally measured Fermi surface (FS)... |

Fingerprints of quantum spin ice in Raman scattering
10.1103/PhysRevB.96.035136 2017-07-19 We develop a theory of the dynamical response of a minimal model of quantum spin ice (QSI) by means of inelastic light scattering. In particular, we are interested in the Raman response of the fractionalized U(1) spin liquid realized in the XXZ QSI. We show t... |

Effect of frustrated exchange interactions and spin-half-impurity on the electronic structure of strongly correlatedNiFe2O4
10.1103/PhysRevB.96.035138 2017-07-19 Spin-polarized density functional calculations, magnetization, and neutron diffraction (ND) measurements are carried out to investigate the magnetic exchange interactions and strong correlation effects in Yb substituted inverse spinel nickel ferrite. In the p... |
