β-Arrestin biosensors reveal a rapid, receptor-dependent activation/deactivation cycle
Susanne Nuber,Ulrike Zabel,Kristina Lorenz,Kristina Lorenz,A. Nuber,Graeme Milligan,Andrew B. Tobin,Martin J. Lohse,Carsten Hoffmann +8 more
TL;DR: GPCRs trigger a rapid, receptor-type-specific, two-step binding and activation process between GPCRs and β-arrestins, which permits their active signalling, and indicates that β-Arrestins remain active after dissociation from receptors, allowing them to remain at the cell surface and presumably signal independently.

Signature of Quantum Criticality in Photoemission Spectroscopy
TL;DR: It is shown theoretically that this step is expected from a highly nonlinear renormalization of the local spin coupling at each Ce site, induced by spin fluctuations on neighboring sites, and provides a general high-temperature indicator for heavy-fermion quasiparticle breakdown at a quantum phase transition.

Influence of reconstruction on the surface state of Au(110)
TL;DR: In this article, high-resolution angle-resolved photoelectron spectroscopy on Au(110) was presented, and relativistic local density approximation calculations were performed to estimate the binding energy on the reconstructed surface.

TL;DR: The temperature dependence of the spectra show the formation of the coherent low-energy heavy-fermion band near the Fermi level, supported by a multiband model calculation in the framework of the dynamical mean-field theory.
The surface state of URu2Si2
F. L. Boariu,A. Nuber,Andrés F. Santander-Syro,Andrés F. Santander-Syro,M. Klein,Frank Förster,Pascal Lejay,Friedrich Reinert +7 more
TL;DR: In this paper, the authors used high-resolution angle-resolved photoemission spectroscopy (ARPES) to find that a hole-like band around Γ having its band maximum at E −35meV, and previously thought to be a bulk band of the system, is indeed a surface state not related to the HO phase transition.
