High-optical-depth, sub-Doppler-width absorption lines at telecom wavelengths in hot, optically driven rubidium vapor
Inna Kviatkovsky, Lucas Pache, Viola-Antonella Zeilberger +4
Doppler broadening presents a major limitation for high-resolution spectroscopy and nonlinear optics in room-temperature atomic vapors. Here, we demonstrate the suppression of Dopp…

Photon Transport in a Gas of Two-Level Atoms: Unveiling Quantum Light Creation
Leonid Yatsenko, Martin Cordier, Lucas Pache +4
We present a theoretical analysis of nearly monochromatic light propagation through a gas of two-level atoms using the Heisenberg-Langevin equation method. Our focus is on the evol…

Few-Photon SUPER: Quantum emitter inversion via two off-resonant photon modes
Quentin W. Richter, Jan M. Kaspari, Thomas K. Bracht +4
With the realization of controlled quantum systems, exploring excitations beyond the resonant case opens new possibilities. We investigate an extended Jaynes-Cummings model where t…
