Support of 2D heavy-fermion research by the National Synchrotron Light Source II, a DOE Office of Science User Facility

The United States Department of Energy (DOE), Office of Science, Basic Energy Science, awarded a grant for research on 2D heavy-fermion materials. ARPES measurements were performed at Beamline 21-ID-1 of the National Synchrotron Light Source II, a DOE Office of Science User Facility operated for the DOE Office of Science by Brookhaven National Laboratory (Contract No. DE-SC0012704). We thank C. Petrovic and Z. Hu for their help with the sample mounting for ARPES. High-magnetic-field transport and tunnel diode oscillator measurements were performed at the National High Magnetic Field Laboratory, which is supported by the National Science Foundation (NSF; Cooperative Agreement No. DMR-1644779) and the State of Florida. The DOE supported the measurement of subkelvin specific heat capacity. resources at the Spallation Neutron Source, a DOE Office of Science User Facility, were used for the heat analysis. The project used the PPMS to perform heat capacity and electrical transport measurements and was supported by a supplement to award. STM equipment support was provided by the Air Force Office of Scientific Research via grant FA9550-21-1-037. Electrical transport measurements of low-dimensional samples were supported by the NSF (DMR-2105048). The Energy Frontier Research Center funded by the DOE, Office of Science, Basic Energy Sciences supported experiments and modeling in the field of quantum physics. The theory calculations by O.E., P.T. and C.-S.O. were supported by an ERC synergy grant (FASTCORR, project 854843), the Swedish Research Council, eSSENCE, STandUPP and the Wallenberg Initiative Materials Science for Sustainability (WISE) funded by the Knut and Alice Wallenberg Foundation (KAW), the Swedish National Infrastructure for Computing, Grupos Consolidados (IT1453-22), and the German Research Foundation through the Cluster of Excellence CUI: Advanced Imaging of Matter (EXC 2056, project ID 390715994) and Project SFB-925 Light-induced Dynamics and Control of Correlated Quantum Systems (Project 170620586).
