These instabilities provide unique opportunities for the emergence of novel states of matter that can either compete or coexist. By exploring materials under such extreme conditions, we uncover rich physical phenomena and gain insights into exotic states of matter. In this talk, I will discuss recent advancements in our understanding of competitive states in materials under high pressure, with a focus on pressure-induced structural and electronic transitions. Key examples include the interplay between charge-density-wave (CDW) and superconducting states in the two-dimensional material BaSbTe₂.₁S₀.₉, the effects of pressure on the magnetic ground state of the colossal magnetoresistance (CMR) material EuCd₂P₂, and enhanced superconductivity observed in metastable structures of lithium. These studies highlight the transformative potential of high-pressure research in revealing new material properties and guiding the development of next-generation technologies. Biography: Shanti Deemyad is an experimental condensed matter physicist and an Associate Professor of Physics at the University of Utah, where she leads the high-pressure research laboratory. She earned her undergraduate degree at Sharif University of Technology and completed her PhD in Physics at Washington University in St. Louis, followed by postdoctoral research at Harvard University. Deemyad’s work focuses on quantum effects in the lattice and electronic properties of condensed matter systems, with a particular emphasis on discovering exotic states of matter under extreme pressure and temperature conditions. A strong advocate for advancing women in science, she co-founded the "Women of High Pressure" group to support and empower women in the high-pressure research community.
