Understanding the quantum critical fluctuations in the frustrated metal YbAgGe
Metallic magnets with frustrated interactions may host novel quantum spin liquid states, but their experimental determination is very challenging. The phases are predicted close to quantum phase transitions, where the energy scale of the critical fluctuations overlaps with the characteristic spin-liquid excitations. YbAgGe is as a frustrated metal that undergoes a magnetic field-driven bicritical quantum phase transition, excluding the possibility of an interfering quantum spin liquid state. Using the material as a model system to establish detailed knowledge of how magnetic frustration affects quantum critical fluctuations. We plan to study the temperature dependence of the critical fluctuations on either side of the bicritical point, which will allow us to determine the universality class of frustrated quantum phase transitions.
