Quantum Back-Action Expands the Excitonic Hilbert Space in a Soft Polar Semiconductor
Arnab Ghosh, Patrick Brosseau, Priya Nagpal +4
Electronic excitations in solids are commonly described within a hierarchy in which the excitonic Hamiltonian is defined first and the lattice acts later through renormalization, r…

Bright-dark exciton splitting in lead halide perovskite crystals accessed via quantum beats in photon echoes
M. Alex Hollberg, Mikhail O. Nestoklon, Artur V. Trifonov +7
Understanding the fine structure of excitons is crucial for optoelectronic and quantum photonic applications of lead halide perovskites. It is demonstrated that polarization-sensit…
