Quantum Criticality in YFe2Al10

Abstract: Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10 shows remarkably strong quantum critical (QC) behavior with no signature of magnetic order down to a temperature of 0.020 K. We propose to use the OSIRIS instrument to probe the low energy magnetic excitations in YFe2Al10 to determine the details of the energy and temperature dependence of these QC fluctuations. Existing measurements hint at local QC behavior with a separability of the energy and momentum dependencies and scaling of the fluctuations with energy and temperature, an important result given the connection between quantum criticality and superconductivity in the Fe-As compounds. OSIRIS is perfect for measuring the low energy spectrum in YFe2Al10 and will shed light on this novel QC material.
