Quantum geometric tensor and wavepacket dynamics in two-dimensional non-Hermitian systems
Y. -M. Robin Hu, Elena A. Ostrovskaya, Eliezer Estrecho
The quantum geometric tensor (QGT) characterizes the local geometry of quantum states, and its components directly account for the dynamical effects observed, e.g., in condensed ma…
Generalized Quantum Geometric Tensor in a Non-Hermitian Exciton-Polariton System
Y. -M. Robin Hu, Elena A. Ostrovskaya, Eliezer Estrecho
In this work, we review different generalizations of the quantum geometric tensor (QGT) in two-band non-Hermitian systems and propose a protocol for measuring them in experiments.…
Wave packet dynamics in a non-Hermitian exciton-polariton system
Y. -M. Robin Hu, Elena A. Ostrovskaya, Eliezer Estrecho
We theoretically investigate the dynamics of wave packets in a generic, non-Hermitian, optically anisotropic exciton-polariton system that exhibits degeneracies of its complex-valu…
