Dynamical beats of short pulses in waveguide QED
Dianqiang Su, Yuan Jiang, Silvia Cardenas-Lopez +4
We study temporal oscillations, known as dynamical beats, developed by a propagating pulse due to its interaction with a near-resonant collective medium of Cs atoms randoml…
Optomechanical feedback cooling of a 5 mm-long torsional mode
Dianqiang Su, Yuan Jiang, Pablo Solano +3
We report three orders of magnitude optical cooling of the fundamental torsional mode of a 5 mm-long, 550 nm diameter optical nanofiber. The rotation of the nanofiber couples to th…
Survey of hyperfine structure measurements in alkali atoms
M. Allegrini, E. Arimondo, L. A. Orozco
The spectroscopic hyperfine constants for all the alkali atoms are reported. For atoms from lithium to cesium, only the long lived atomic isotopes are examined. For francium, the m…
Optical precursors in waveguide quantum electrodynamics
Silvia Cardenas-Lopez, Pablo Solano, Luis A. Orozco +1
When a broadband signal propagates through a dispersive medium, some frequency components move faster than the center of the pulse. This leads to the appearance of precursors, tran…
Many-body Signatures of Collective Decay in Atomic Chains
Stuart J. Masson, Igor Ferrier-Barbut, Luis A. Orozco +2
Fully inverted atoms placed at exactly the same location synchronize as they deexcite, and light is emitted in a burst (known as "Dicke's superradiance"). We investigate the role o…
Torsional optomechanical cooling of a nanofiber
Dianqiang Su, Pablo Solano, Jeffrey D. Wack +2
We demonstrate the optomechanical cooling of a tapered optical nanofiber by coupling the polarization of light to the mechanical angular momentum of the system. The coupling is ena…
