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…
