Quantum Geometry: How to Picture Bound Electrons in Infinite Lattices

On  May 19, 2025
Quantalps federation is pleased to announce the following Theory Seminar by Raquel Queiroz (University of Columbia).
Abstract: The concept of quantum geometry has been at the forefront of condensed matter physics, starting from how quantized Berry curvature leads to quantized Hall conductivity, anomalous velocities in Dirac metals, or other topological responses in a growing list of topological materials. Recently, the real part of the quantum geometric tensor - the quantum metric - has also been suggested to play an important role, both in response and in the tendency for materials to assume correlated ground states at low temperatures. In this talk, I will give a local picture of quantum geometry to create an intuition about what it is and when it is essential, relating it to how bonds are formed in infinite lattices.
