Time-Reversed Superfluorescence in a Polaronic Quantum Material
Arnab Ghosh, Patrick Brosseau, Dmitry N. Dirin +2
Superfluorescence, the cooperative burst of spontaneous emission from an ensemble of dipoles, arises when microscopic oscillators spontaneously synchronize their phases. Here we sh…

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…

The Comparison of Colloidal PbS QD Photoconductors and Hybrid Phototransistors
Gökhan Kara, Lorenzo J. A. Ferraresi, Dmitry N. Dirin +4
The simplicity in the fabrication of photoconductors makes them a valuable choice to investigate optoelectronic properties of colloidal quantum dot (cQD) films. Lateral photoconduc…
