Low-energy V t2g orbital excitations in NdVO3
J. Laverock, B. Chen, A. R. H. Preston +7
The electronic structure of NdVO3, YVO3 has been investigated as a function of sample temperature using resonant inelastic soft x-ray scattering at the V L3-edge. Most of the obser…
Direct Observation of Decoupled Structural and Electronic Transitions and an Ambient Pressure Monoclinic-Like Metallic Phase of VO
J. Laverock, S. Kittiwatanakul, A. A. Zakharov +5
We report the simultaneous measurement of the structural and electronic components of the metal-insulator transition of VO using electron and photoelectron spectroscopies and m…
Fractional (Chern and topological) insulators
Titus Neupert, Claudio Chamon, Thomas Iadecola +2
We review various features of interacting Abelian topological phases of matter in two spatial dimensions, placing particular emphasis on fractional Chern insulators (FCIs) and frac…
Conformal field theories at non-zero temperature: operator product expansions, Monte Carlo, and holography
Emanuel Katz, Subir Sachdev, Erik S. Sorensen +1
We compute the non-zero temperature conductivity of conserved flavor currents in conformal field theories (CFTs) in 2+1 spacetime dimensions. At frequencies much greater than the t…
Criticality and Mott-glass phase in a disordered 2D quantum spin systems
Nvsen Ma, Anders W. Sandvik, Dao-Xin Yao
We use quantum Monte Carlo simulations to study a disordered S=1/2 Heisenberg quantum spin model with three different nearest-neighbor interactions, J1<=J2<=J3, on the square latti…
Accessing topological order in fractionalized liquids with gapped edges
Thomas Iadecola, Titus Neupert, Claudio Chamon +1
We consider manifestations of topological order in time-reversal-symmetric fractional topological liquids (TRS-FTLs), defined on planar surfaces with holes. We derive a formula for…
Effective field theory for the bulk-edge correspondence in a two-dimensional Z_2 topological insulator with Rashba interactions
Pedro R. S. Gomes, Po-Hao Huang, Claudio Chamon +1
We determine the effective field theory in (2+1)-dimensional space and time that captures the long wave length and low-energy limit of fermions hopping on a honeycomb lattice at ha…
Vanishing spin stiffness in the spin-1/2 Heisenberg chain for any nonzero temperature
J. M. P. Carmelo, T. Prosen, D. K. Campbell
Whether at zero spin density and finite temperatures the spin stiffness of the spin- chain is finite or vanishes remains an unsolved and controversial issue,…
Spin-dependent polaron formation dynamics in EuYMnO probed by femtosecond pump-probe spectroscopy
Diyar Talbayev, Jinho Lee, Stuart A. Trugman +5
We present a femtosecond optical pump-probe study of the multiferroic manganite EuYMnO. The optical response of the material at pump energies of 1.55 and 3.1…
Real-Time Simulation of Large Open Quantum Spin Systems driven by Measurements
D. Banerjee, F. -J. Jiang, M. Kon +1
We consider a large quantum system with spins whose dynamics is driven entirely by measurements of the total spin of spin pairs. This gives rise to a dissipative coup…
Quantum Monte Carlo studies of spinons in one-dimensional spin systems
Ying Tang, Anders W. Sandvik
Observing constituent particles with fractional quantum numbers in confined and deconfined states is an interesting and challenging problem in quantum many-body physics. Here we fu…
Wire deconstructionism of two-dimensional topological phases
Titus Neupert, Claudio Chamon, Christopher Mudry +1
A scheme is proposed to construct integer and fractional topological quantum states of fermions in two spatial dimensions. We devise models for such states by coupling wires of non…
Erratum for "Elementary formula for the Hall conductivity of interacting systems"
Titus Neupert, Luiz Santos, Claudio Chamon +1
When deriving a formula for the Hall conductivity of interacting electrons in Phys. Rev. B 86, 165133, we have relied on an unjustified implicit assumption that a certain gauge cho…
