Spin-Orbital Entanglement Emerging from Frustration in the Kugel-Khomskii Model
W. Brzezicki, A. M. Oleś
We investigate the zero-temperature phase diagrams of the bilayer square-lattice Kugel-Khomskii () model involving entangled and singlet phases using mean-field cluster approa…
Ultrafast photodoping and effective Fermi-Dirac distribution of the Dirac particles in Bi2Se3
A. Crepaldi, B. Ressel, F. Cilento +7
We exploit time- and angle- resolved photoemission spectroscopy to determine the evolution of the out-of-equilibrium electronic structure of the topological insulator Bi2Se. The re…
The Microstructure of Tool Steel after Low Temperature Ion Nitriding
L. F. Zagonel, E. J. Mittemeijer, F. Alvarez
The microstructural development in H13 tool steel upon nitriding by an ion beam process was investigated. The nitriding experiments were performed at a relatively low temperature o…
Depth profile of the ferromagnetic order in a YBaCuO / LaCaMnO superlattice on a LSAT substrate: a polarized neutron reflectometry study
M. A. Uribe-Laverde, D. K. Satapathy, I. Marozau +10
Using polarized neutron reflectometry (PNR) we have investigated a YBa2Cu3O7(10nm)/La2/3Ca1/3MnO3(9nm)]10 (YBCO/LCMO) superlattice grown by pulsed laser deposition on a La0.3Sr0.7A…
Evidence of a critical hole concentration in underdoped YBaCuO single crystals revealed by Cu NMR
S. -H. Baek, T. Loew, V. Hinkov +4
We report a Cu NMR investigation in detwinned YBaCuO single crystals, focusing on the highly underdoped regime (y=6.35-6.6). Measurements of both the spectra and…
Retardation effects and the Coulomb pseudopotential in the theory of superconductivity
Johannes Bauer, Jong E. Han, Olle Gunnarsson
In the theory of electron-phonon superconductivity both the magnitude of the electron-phonon coupling as well as the Coulomb pseudopotential are important to determine th…
