Aspen Center for Physics presents The Heinz R. Pagels Memorial Lectures Series, with free public talks each Wednesday evening from June 26 - August 28, 2024. The talks will be in Flug Forum, located at the Aspen Center for Physics. Lectures are free and begin promptly at 5:30pm. Guests are invited to arrive at 5pm to enjoy tea and cookies before the lecture. The lectures will last 50 minutes followed by a 10 minute Q&A. Please RSVP at aspenphys.org.
Scientists like to organize phenomena in schemes with simple rules but ample predicting power. The periodic table is one of the most successful examples of this: just by labeling the different possible orbitals of a hydrogen atom, we can predict with great accuracy the existence and properties of most elements and alloys. But in any good classification scheme, outliers become apparent and hint at a necessary refinement of physical laws. What is missing in the periodic table is that matter is not formed by one but by billions of billions of atoms together, and electrons in orbits around each atom can be fundamentally altered by their surroundings, altering their weight and spin, among other properties. In this talk, I will describe how we now understand that electrons behave as if they live in a curved space, where most physical properties are dictated by the geometry itself.
In her talk, Raquel will introduce the new notion of quantum geometry in quantum materials and its crucial role in determining properties and phases of matter. She will discuss how quantum geometry is essential to protect emergent phases where interactions between electrons are strong and electrons behave in remarkable ways, such as those where electrons pair up and condense into a macroscopic quantum state or phases where electrons are broken into independent fractions with new quantum statistics.
Raquel Queiroz is an Assistant Professor of Physics at Columbia University and a Visiting Scholar at the Center for Computation Quantum Physics, Flatiron Institute in New York City. She received her PhD from the Max Planck Institute for Solid State Physics in Stuttgart, Germany, in 2015 and was a postdoctoral fellow at the Weizmann Institute of Science in Israel from 2016 until 2021. In 2022, she established her group at Columbia University, where she studied topological and geometric properties of solids, primarily how quantum geometry affects electronic response, collective phenomena, and behavior in the presence of disorder. Her work is deeply motivated by current experimental findings and a constant dialogue with experimental colleagues.
