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…
Landau Polarons as Generators of Quantum-Coherent States
Arnab Ghosh, Patrick Brosseau, Dmitry N. Dirin +3
Since Landau's theory, polarons have been understood as quasiparticles in which charges are dressed by the lattice field, yet decades of transport and spectroscopic studies have yi…
Optical orientation of excitons and charged carriers in MAPbI perovskite single crystals in the orthorhombic phase
Nataliia E. Kopteva, Dmitri R. Yakovlev, Eyüp Yalcin +6
Optical orientation of exciton and carrier spins by circularly polarized light is the basic phenomenon in the spin physics of semiconductors. Here, we investigate spin orientation…
Exciton-polaritons in CsPbBr crystals revealed by optical reflectivity in high magnetic fields and two-photon spectroscopy
Dmitri R. Yakovlev, Scott A. Crooker, Marina A. Semina +5
Cesium lead bromide (CsPbBr) is a representative material of the emerging class of lead halide perovskite semiconductors that possess remarkable optoelectronic properties. Its…
Giant optical orientation of exciton spins in lead halide perovskite crystals
Natalia E. Kopteva, Dmitri R. Yakovlev, Eyüp Yalcin +11
Optical orientation of carrier spins by circularly polarized light is the basis of spin physics in semiconductors. Here, we demonstrate strong optical orientation of 85\%, approach…
Weak dispersion of exciton Landé factor with band gap energy in lead halide perovskites: Approximate compensation of the electron and hole dependences
N. E. Kopteva, D. R. Yakovlev, E. Kirstein +11
The photovoltaic and optoelectronic properties of lead halide perovskite semiconductors are controlled by excitons, so that investigation of their fundamental properties is of crit…
