Néel and stripe ordering from spin-orbital entanglement in -SrCrO
Z. H. Zhu, W. Hu, C. A. Occhialini +6
The rich phenomenology engendered by the coupling between the spin and orbital degrees of freedom has become appreciated as a key feature of many strongly-correlated electron syste…
Distinct Magnetic Phases in Structurally Uniform SrCoO
Z. H. Zhu, F. J. Rueckert, J. I. Budnick +7
Two magnetic phase transitions have been noted for SrCoO for near-stoichiometric oxygen concentrations (small y). Using muon spin rotation and neutron scattering experiment…
Spin-Polarized Quantum Well States on BiFeSe
Michael M. Yee, Z. -H. Zhu, Anjan Soumyanarayanan +8
Low temperature scanning tunneling microscopy is used to image the doped topological insulator BiFeSe. Interstitial Fe defects allow the detection of quasiparticle…
Photoelectron spin-polarization-control in the topological insulator Bi2Se3
Z. -H. Zhu, C. N. Veenstra, S. Zhdanovich +9
We study the manipulation of the photoelectron spin-polarization in BiSe by spin- and angle-resolved photoemission spectroscopy. General rules are established that enable c…
Polarity-driven surface metallicity in SmB
Z. -H. Zhu, A. Nicolaou, G. Levy +7
By a combined angle-resolved photoemission spectroscopy and density functional theory study, we discover that the surface metallicity is polarity-driven in SmB. Two surface sta…
Layer-by-layer entangled spin-orbital texture of the topological surface state in Bi2Se3
Z. -H. Zhu, C. N. Veenstra, G. Levy +7
We study Bi2Se3 by polarization-dependent angle-resolved photoemission spectroscopy (ARPES) and density-functional theory slab calculations. We find that the surface state Dirac fe…
Perovskite BaCrO_{3}: completing a materials system with an anomalous Mott transition
Z. H. Zhu, F. J. Rueckert, J. I. Budnick +4
We have synthesized and characterized laser-deposited film samples of perovskite BaCrO_{3}, a missing member of the perovskite-chromate family. The BaCrO_{3} films have a substanti…
Determining the Surface-To-Bulk Progression in the Normal-State Electronic Structure of Sr2RuO4 by Angle-Resolved Photoemission and Density Functional Theory
C. N. Veenstra, Z. -H. Zhu, B. Ludbrook +9
In search of the potential realization of novel normal-state phases on the surface of Sr2RuO4 - those stemming from either topological bulk properties or the interplay between spin…
Na2IrO3 as a spin-orbit-assisted antiferromagnetic insulator with a 340 meV gap
R. Comin, G. Levy, B. Ludbrook +10
We study Na2IrO3 by ARPES, optics, and band structure calculations in the local-density approximation (LDA). The weak dispersion of the Ir 5d-t2g manifold highlights the importance…
Surface-enhanced charge-density-wave instability in underdoped Bi2201
J. A. Rosen, R. Comin, G. Levy +20
Neutron and x-ray scattering experiments have provided mounting evidence for spin and charge ordering phenomena in underdoped cuprates. These range from early work on stripe correl…
Rashba spin-splitting control at the surface of the topological insulator Bi2Se3
Z. -H. Zhu, G. Levy, B. Ludbrook +11
The electronic structure of Bi2Se3 is studied by angle-resolved photoemission and density functional theory. We show that the instability of the surface electronic properties, obse…
