Coherent spin waves in a maximal entropy phase
Arnau Romaguera, Eugenio Paris, Elizabeth Skoropata +24
In solids, disorder is conventionally regarded as detrimental to coherence. It typically localizes and dampens collective excitations, as exemplified by Anderson localization or th…
Nature of the metallic and in-gap states in Ni-doped SrTiO
Fatima Alarab, Karol Hricovini, Berengar Leikert +6
Epitaxial thin films of SrTiO(100) doped with 6% and 12% Ni are studied with resonant angle-resolved photoelectron spectroscopy (ARPES) at the Ti and Ni L2,3-edges. We find tha…
k-dependent proximity-induced modulation of spin-orbit interaction in MoSe2 interfaced with amorphous Pb
Fatima Alarab, Ján Minár, Procopios Constantinou +4
The ability to modulate the spin-orbit (SO) interaction is crucial for engineering a wide range of spintronics-based quantum devices, extending from state-of-the-art data storage t…
Electron-polaron dichotomy of charge carriers in perovskite oxides
Marius-Adrian Husanu, Lorenzo Vistoli, Carla Verdi +10
Many transition metal oxides (TMOs) are Mott insulators due to strong Coulomb repulsion between electrons, and exhibit metal-insulator transitions (MITs) whose mechanisms are not a…
Three-dimensional Fermi surface of 2H-NbSe - Implications for the mechanism of charge density waves
F. Weber, R. Hott, R. Heid +4
We investigate the three-dimensional electronic structure of the seminal charge-density-wave (CDW) material 2H-NbSe by soft x-ray angle-resolved photoelectron spectroscopy and…
Energetic, spatial and momentum character of a buried interface: the two-dimensional electron gas between two metal oxides
S. Nemšák, G. Conti, A. X. Gray +32
The interfaces between two condensed phases often exhibit emergent physical properties that can lead to new physics and novel device applications, and are the subject of intense st…
Fermi surface of three-dimensional La1-xSrxMnO3 explored by soft-X-ray ARPES: Rhombohedral lattice distortion and its effect on magnetoresistance
L. L. Lev, J. Krempaský, U. Staub +12
Electronic structure of the three-dimensional colossal magnetoresistive perovskite La1-xSrxMnO3 has been established using soft-X-ray ARPES with its intrinsically sharp definition…
Tuning electronic correlations in transition metal pnictides: chemistry beyond the valence count
E. Razzoli, C. E. Matt, M. Kobayashi +14
The effects of electron-electron correlations on the low-energy electronic structure and their relationship with unconventional superconductivity are central aspects in the researc…
Dimensionality-tuned electronic structure of nickelate superlattices explored by soft-x-ray angle resolved photoelectron spectroscopy
G. Berner, M. Sing, F. Pfaff +13
The electronic and magnetic properties of epitaxial LaNiO3/LaAlO3 superlattices can be tuned by layer thickness and substrate-induced strain. Here, we report on direct measurements…
Asymmetry of collective excitations in electron and hole doped cuprate superconductors
W. S. Lee, J. J. Lee, E. A. Nowadnick +10
High-temperature superconductivity (HTSC) mysteriously emerges upon doping holes or electrons into insulating copper oxides with antiferromagnetic (AFM) order. It has been thought…
Mixed Dimensionality of Confined Conducting Electrons in the Surface Region of SrTiO
N. C. Plumb, M. Salluzzo, E. Razzoli +16
Using angle-resolved photoemission spectroscopy, we show that the recently-discovered surface state on SrTiO consists of non-degenerate states with different dimensi…

V. B. Zabolotnyy, A. A. Kordyuk, D. Evtushinsky +9
As established by scanning tunneling microscopy (STM) cleaved surfaces of the high temperature superconductor YBaCuO develop charge density wave (CDW) modulations i…
