Experimental measurement of the divergent quantum metric of an exceptional point
Qing Liao, Charly Leblanc, Jiahuan Ren +6
The geometry of Hamiltonian's eigenstates is encoded in the quantum geometric tensor (QGT). It contains both the Berry curvature, central to the description of topological matter a…

Quantum metric and wavepackets at exceptional points in non-Hermitian systems
D. D. Solnyshkov, C. Leblanc, L. Bessonart +5
The usual concepts of topological physics, such as the Berry curvature, cannot be applied directly to non-Hermitian systems. We show that another object, the quantum metric, which…
