In quantum mechanics, the geometry of quantum states has emerged as a powerful framework for understanding phenomena ranging from electrical conductivity to superconductivity. One research direction aims to extend these geometric concepts to non-Hermitian quantum mechanics—where systems can exchange energy with their environment—including the generalization of the Berry phase, a key geometric quantity, to the non-Hermitian case.
