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…
Emergence of unidirectionality and phase separation in optically dense emitter ensembles
Kasper J. Kusmierek, Max Schemmer, Sahand Mahmoodian +1
The transmission of light through an ensemble of two-level emitters in a one-dimensional geometry is commonly described by one of two emblematic models of quantum electrodynamics (…
Simple analytical model describing the collective nonlinear response of an ensemble of two-level emitters weakly coupled to a waveguide
Max Schemmer, Martin Cordier, Lucas Pache +3
We model and investigate the collective nonlinear optical response of an ensemble of two-level emitters that are weakly coupled to a single-mode waveguide. Our approach generalizes…
Magic-wavelength nanofiber-based two-color dipole trap with sub- spacing
Lucas Pache, Martin Cordier, Hector Letellier +4
We report on the realization and characterization of a novel magic-wavelength nanofiber-based two-color optical dipole trap for cesium that allows us to generate two diametral peri…
Ultracold LiCr: a new pathway to quantum gases of paramagnetic polar molecules
Stefano Finelli, Alessio Ciamei, Beatrice Restivo +8
Quantum gases of doubly-polar molecules represent appealing frameworks for a variety of cross-disciplinary applications, encompassing quantum simulation and computation, controlled…
Tailoring photon statistics with an atom-based two-photon interferometer
Martin Cordier, Max Schemmer, Philipp Schneeweiss +2
Controlling the photon statistics of light is paramount for quantum science and technologies. Recently, we demonstrated that transmitting resonant laser light past an ensemble of t…
Will a single two-level atom simultaneously scatter two photons?
Luke Masters, Xinxin Hu, Martin Cordier +5
The interaction of light with a single two-level emitter is the most fundamental process in quantum optics, and is key to many quantum applications. As a distinctive feature, two p…
Higher-order mean-field theory of chiral waveguide QED
Kasper J. Kusmierek, Sahand Mahmoodian, Martin Cordier +6
Waveguide QED with cold atoms provides a potent platform for the study of non-equilibrium, many-body, and open-system quantum dynamics. Even with weak coupling and strong photon lo…
Unraveling two-photon entanglement via the squeezing spectrum of light traveling through nanofiber-coupled atoms
Jakob Hinney, Adarsh S. Prasad, Sahand Mahmoodian +5
We observe that a weak guided light field transmitted through an ensemble of atoms coupled to an optical nanofiber exhibits quadrature squeezing. From the measured squeezing spectr…
Correlating photons using the collective nonlinear response of atoms weakly coupled to an optical mode
Adarsh S. Prasad, Jakob Hinney, Sahand Mahmoodian +6
Photons in a nonlinear medium can repel or attract each other, resulting in a strongly correlated quantum many-body system. Typically, such strongly correlated states of light aris…
