Abstract

Quantum materials have fascinating quantum phenomena result from interplay of charge, spin, orbitals and lattice. Materials with strong electron-electron correlation show rich phase diagrams containing different ground states, which can be tuned by external parameters, e.g. doping, pressures, etc. Recently, uniaxial stress has become a practical experimental tuning knob in studying quantum materials. My research interests since the past decade have mainly focused on tuning unconventional superconductors. Here, I will take Sr₂RuO₄ as an example to demonstrate versatility of the uniaxial stress techniques. I will, then, discuss our main findings based on the thermodynamic probes (elastocaloric effect and heat capacity) I have developed.
