Coherent heavy quasiparticles in CePt5 surface alloy
M. Klein, A. Nuber, H. Schwab +9
We report on the results of a high-resolution angle-resolved photoemission (ARPES) study on the ordered surface alloy CePt5. The temperature dependence of the spectra show the form…
High-temperature signatures of quantum criticality in heavy fermion systems
J. Kroha, M. Klein, A. Nuber +3
We propose a new criterion for distinguishing the Hertz-Millis (HM) and the local quantum critical (LQC) mechanism in heavy fermion systems with a magnetic quantum phase transition…
Fermi surface instability at the hidden-order transition of URu2Si2
A. F. Santander-Syro, M. Klein, F. L. Boariu +3
Solids with strong electron correlations generally develop exotic phases of electron matter at low temperatures. Among such systems, the heavy-fermion semi-metal URu2Si2 presents a…
Echo of the Quantum Phase Transition of CeCuAu in XPS: Breakdown of Kondo Screening
M. Klein, J. Kroha, H. v. Loehneysen +2
We present an X-ray photoemission study of the heavy-fermion system CeCuAu across the magnetic quantum phase transition of this compound at temperatures above the singl…
Signature of quantum criticality in photoemission spectroscopy at elevated temperature
M. Klein, A. Nuber, F. Reinert +3
A quantum phase transition (QPT) in a heavy-fermion (HF) compound may destroy the Fermi liquid groundstate. However, the conditions for this breakdown have remained obscure. We rep…
