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…

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…

Room-temperature cavity exciton-polariton condensation in perovskite quantum dots
Ioannis Georgakilas, David Tiede, Darius Urbonas +13
The exploitation of the strong light-matter coupling regime and exciton-polariton condensates has emerged as a compelling approach to introduce strong interactions and nonlineariti…
