DESCRIPTION:"Probing the Superconducting State of Sr₂RuO₄ with Strains:
  New Perspectives on an Old Puzzle"\n\n \n\nPresented by Dr. Giordano Matt
 oni\, Program Specific Assistant Professor\, from Kyoto University in Japa
 n\n\n \n\nSr₂RuO₄ has fascinated physicists for over 30 years as a lea
 ding candidate for unconventional superconductivity\, a state of matter wh
 ere electrons pair up in unusual ways not explained by conventional theori
 es. Despite intense study\, the exact nature of its superconducting state 
 remains elusive. At the heart of the debate lies the symmetry of the order
  parameter\, which describes how electrons pair in the superconducting pha
 se. Recent experiments applying uniaxial strain have added new insights bu
 t also deepened the mystery. In particular\, the smooth variation of the s
 uperconducting transition temperature (Tc) under certain strain directions
  suggests a simple\, one-component order parameter. On the other hand\, ul
 trasound measurements detecting sudden changes in the elastic moduli of Sr
 ₂RuO₄ point toward a more complex\, two-component scenario.\n\n \n\nIn
  this talk\, I will first give an overview of Sr₂RuO₄ and the long-sta
 nding puzzle surrounding its superconductivity. I will then introduce our 
 recent experimental developments involving both uniaxial and shear strains
  in Sr₂RuO₄ crystals and measuring changes in Tc using sensitive magne
 tic techniques. Our findings offer a fresh angle on the problem and help t
 est the competing theories of the superconducting state. This approach hig
 hlights the broader potential of strain as a powerful and versatile tool f
 or tuning and controlling the electronic properties of quantum materials.
