Emergence of Fermi arcs and novel magnetic splitting in an antiferromagnet
Benjamin Schrunk, Yevhen Kushnirenko, Brinda Kuthanazhi +14
The Fermi arcs are signatures of exotic states in solids because they defy conventional concept of Fermi surfaces as closed contours in momentum space. Fermi arcs were first discov…
Lifetime of quasi-particles in the nearly-free electron metal Sodium
D. V. Potorochin, R. Kurleto, O. J. Clark +8
We report a high-resolution angle-resolved photoemission (ARPES) study of the prototypical nearly-free-electron metal sodium. The observed mass enhancement is slightly smaller than…
Strong spin dependence of correlation effects in Ni due to Stoner excitations
J. Sánchez-Barriga, R. Ovsyannikov, J. Fink
Using high-resolution angle-resolved photoemission, we observe a strong spin-dependent renormalization and lifetime broadening of the quasiparticle excitations in the electronic ba…
Absence of Giant Spin Splitting in the Two-Dimensional Electron Liquid at the Surface of SrTiO (001)
S. McKeown Walker, S Riccò, F. Y. Bruno +10
We reinvestigate the putative giant spin splitting at the surface of SrTiO reported by Santander-Syro [Nature Mat. 13, 1085 (2014)]. Our spin- and angle-resolved photo…
Tailoring the nature and strength of electron-phonon interactions in the SrTiO(001) two-dimensional electron liquid
Z. Wang, S. McKeown Walker, A. Tamai +20
Surfaces and interfaces offer new possibilities for tailoring the many-body interactions that dominate the electrical and thermal properties of transition metal oxides. Here, we us…
Angle-resolved and core-level photoemission study of interfacing the topological insulator Bi1.5Sb0.5Te1.7Se1.3 with Ag, Nb and Fe
N. de Jong, E. Frantzeskakis, B. Zwartsenberg +7
Interfaces between a bulk-insulating topological insulator (TI) and metallic adatoms have been studied using high-resolution, angle-resolved and core-level photoemission. Fe, Nb an…
Samarium hexaboride: A trivial surface conductor
P. Hlawenka, K. Siemensmeyer, E. Weschke +9
Recent theoretical and experimental studies suggest that SmB is the first topological Kondo insulator: A material in which the interaction between localized and itinerant elect…
About the strength of correlation effects in the electronic structure of iron
J. Sanchez-Barriga, J. Fink, V. Boni +13
The strength of electronic correlation effects in the spin-dependent electronic structure of ferromagnetic bcc Fe(110) has been investigated by means of spin and angle-resolved pho…
