Controlling crystal cleavage in Focused Ion Beam shaped specimens for surface spectroscopy
A. Hunter, C. Putzke, I. Gaponenko +3
Our understanding of quantum materials is commonly based on precise determinations of their electronic spectrum by spectroscopic means, most notably angle-resolved photoemission sp…
Magnon interactions in a moderately correlated Mott insulator
Qisi Wang, S. Mustafi, E. Fogh +20
Quantum fluctuations in low-dimensional systems and near quantum phase transitions have significant influences on material properties. Yet, it is difficult to experimentally gauge…
4 electron temperature driven ultrafast electron localization
Kohei Yamagami, Hiroki Ueda, Urs Staub +9
Valence transitions in strongly correlated electron systems are caused by orbital hybridization and Coulomb interactions between localized and delocalized electrons. The transition…
Interfacial and thickness effects in LaSrMnO/YBaCuO superlattices
V. A. M. Lima, M. C. O. Aguiar, N. C. Plumb +2
Superlattices of correlated oxides have been used to explore interfacial effects and to achieve additional control over the physical properties of individual constituents. In this…
Fermi Surface Nesting with Heavy Quasiparticles in the Locally Noncentrosymmetric Superconductor CeRhAs
Yi Wu, Yongjun Zhang, Sailong Ju +15
The locally noncentrosymmetric heavy fermion superconductor CeRhAs has attracted considerable interests due to its rich superconducting phases, accompanied by a quadrupole…
The fate of quasiparticles at high-temperature
A. Hunter, S. Beck, E. Cappelli +17
We study the temperature evolution of quasiparticles in the correlated metal SrRuO. Our angle resolved photoemission data show that quasiparticles persist up to temperature…
