Measurement of Coherent Polarons in the Strongly Coupled Antiferromagnetically Ordered Iron-Chalcogenide Fe1.02Te using Angle-Resolved Photoemission Spectroscopy

Zhongkai Liu, Ruihua He, Donghui Lu +12

The nature of metallicity and the level of electronic correlations in the antiferromagnetically ordered parent compounds are two important open issues for the iron-based supercondu…

Kerr effect as evidence of gyrotropic order in the cuprates

Pavan Hosur, A. Kapitulnik, S. A. Kivelson +2

The Kerr effect can arise in a time-reversal invariant dissipative medium that is "gyrotropic", i.e. one that breaks inversion () and all mirror symmetries. Examples of…

p6 - Chiral Resonating Valence Bonds in the Kagome Antiferromagnet

Sylvain Capponi, V. Ravi Chandra, Assa Auerbach +1

The Kagome Heisenberg antiferromagnet is mapped onto an effective Hamiltonian on the star superlattice by Contractor Renormalization. Comparison of ground state energies on large l…

Competition between antiferromagnetic and charge density wave order in the half filled Hubbard-Holstein model

E. A. Nowadnick, S. Johnston, B. Moritz +2

We present a determinant quantum Monte Carlo study of the competition between instantaneous on-site Coulomb repulsion and retarded phonon-mediated attraction between electrons, as…

Multiconfigurational nature of 5f orbitals in uranium and plutonium intermetallics

C. H. Booth, Yu Jiang, D. L. Wang +10

Uranium and plutonium's 5f electrons are tenuously poised between strongly bonding with ligand spd-states and residing close to the nucleus. The unusual properties of these element…

Correlation tuned cross-over between thermal and nonthermal states following ultrafast transient pumping

B. Moritz, A. F. Kemper, M. Sentef +2

We examine electron-electron mediated relaxation following excitation of a correlated system by an ultrafast electric field pump pulse. The results reveal a dichotomy in the tempor…

Quantum Dynamics of the Hubbard-Holstein Model in Equilibrium and Non-Equilibrium: Application to Pump-Probe Phenomena

G. De Filippis, V. Cataudella, E. A. Nowadnick +3

The spectral response and physical features of the 2D Hubbard-Holstein model are calculated both in equilibrium at zero and low chemical dopings, and after an ultra short powerful…
