Abstract given by the source: Quantum materials are materials with strong electronic correlation and emergent orders. In this research project we will experimentally study quantum materials in systems with strongly anisotropic properties, including heavy-fermion systems with purported quantum criticality, quantum spin liquids, and Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) phases. For the studies, we will apply our experimental technique of ultra-small sample specific heat measurements to investigate single crystals of such quantum materials at low temperatures (down to 10 mK) and high magnetic fields (45 T and beyond) with sample rotation. The technique, that we have been developing for many years, is now fully ready to firmly establish its place as a key materials characterization method in strong magnetic fields. The theoretical understanding of strongly correlated systems is a great challenge. Theoretical frameworks of quantum criticality and heavy fermions are not easily reconciled with each other. Each new material also brings additional puzzling observations. High-quality thermodynamic characterization is a key component for assisting this theoretical understanding and development.
