Observation of multipartite spin entanglement in a cuprate chain
S. F. R. TenHuisen, Z. Shen, V. Bhartiya +17
Quantum materials are believed to host highly entangled states of matter, but probing and quantifying such entanglement has long remained experimentally elusive. Here, we use reson…
Ultrafast renormalization of the onsite Coulomb repulsion in a cuprate superconductor
Denitsa R. Baykusheva, Hoyoung Jang, Ali A. Husain +14
Ultrafast lasers are an increasingly important tool to control and stabilize emergent phases in quantum materials. Among a variety of possible excitation protocols, a particularly…
Light-Driven Raman Coherence as a Non-Thermal Route to Ultrafast Topology Switching
C. Vaswani, L. -L. Wang, D. H. Mudiyanselage +14
A grand challenge underlies the entire field of topology-enabled quantum logic and information science: how to establish topological control principles driven by quantum coherence…
Doping Dependence of Collective Spin and Orbital Excitations in Spin 1 Quantum Antiferromagnet LaSrNiO Observed by X-rays
G. Fabbris, D. Meyers, L. Xu +14
We report the first empirical demonstration that resonant inelastic x-ray scattering (RIXS) is sensitive to \emph{collective} magnetic excitations in systems by probing the N…
Phonon anomalies in some iron-telluride materials
C. C. Homes, Y. M. Dai, J. Schneeloch +2
The detailed temperature dependence of the infrared-active mode in FeTe ( K) and FeTe ( K) has been examined, and the position, width,…
Nearly Perfect Fluidity in a High Temperature Superconductor
J. D. Rameau, T. J. Reber, H. -B. Yang +4
Perfect fluids are characterized as having the smallest ratio of shear viscosity to entropy density, η/s, consistent with quantum uncertainty and causality. So far, nearly perfect…
Spectral weight transfer in strongly correlated FeTe
Y. M. Dai, A. Akrap, J. Schneeloch +5
The temperature dependence of the in-plane optical conductivity has been determined for FeTe above and below the magnetic and structural transition at K. Th…
Spin Configuration and Scattering Rates on the Heavily Electron-doped Surface of Topological Insulator BiSe
Z. -H. Pan, E. Vescovo, A. V. Fedorov +6
Heavily electron-doped surfaces of BiSe have been studied by spin and angle resolved photoemission spectroscopy. Upon doping, electrons occupy a series of {\bf k}-split pai…
NMR Studies of pseudogap and electronic inhomogeneity in BiSrCaCuO
J. Crocker, A. P. Dioguardi, N. apRoberts-Warren +6
We report O NMR measurements in single crystals of overdoped BiSrCaCuO with K. We measure the full anisotropy of the planar oxygen Knight shift,…
A Comparison of Stripe Modulations in LaBaCuO and LaNdSrCuO
S. B. Wilkins, M. P. M. Dean, Jörg Fink +10
We report combined soft and hard x-ray scattering studies of the electronic and lattice modulations associated with stripe order in LaBaCuO and LaN…
Electronic Structure of the Topological Insulator Bi2Se3 Using Angle-Resolved Photoemission Spectroscopy: Evidence for a Nearly Full Surface Spin Polarization
Z. -H. Pan, E. Vescovo, A. V. Fedorov +5
We performed high-resolution spin- and angle-resolved photoemission spectroscopy studies of the electronic structure and the spin texture on the surface of BiSe, a model to…
Direct Determination of Electron-Phonon Coupling Matrix Element in a Correlated System
Huajun Qin, Junren Shi, Yanwei Cao +7
High-resolution electron energy loss spectroscopy measurements have been carried out on an optimally doped cuprate Bi2Sr2CaCu2O8+δ. The momentum-dependent linewidth and the dispers…
Spatially modulated "Mottness" in La2-xBaxCuO4
P. Abbamonte, A. Rusydi, S. Smadici +3
Stripe phases were predicted to arise in doped antiferromagnets through competition between magnetism and the kinetic energy of mobile carriers (typically holes). In copper-oxides…
