Suppression of molecular decay in ultracold gases without Fermi statistics
J. P. D'Incao, B. D. Esry
We study inelastic processes for ultracold three-body systems in which only one interaction is resonant. We have found that the decay rates for weakly bound molecules due to collis…
Femtosecond induced transparency and absorption in the extreme ultraviolet by coherent coupling of the He 2s2p (1P0) and 2p2 (1Se) double excitation states with 800 nm light
Zhi-Heng Loh, Chris H. Greene, Stephen R. Leone
Femtosecond high-order harmonic transient absorption spectroscopy is used to observe electromagnetically induced transparency-like behavior as well as induced absorption in the ext…
Molecular Recollision Interferometry in High Harmonic Generation
Xibin Zhou, Robynne Lock, Wen Li +3
We use extreme-ultraviolet interferometry to measure the phase of high-order harmonic generation from transiently aligned CO2 molecules. We unambiguously observe a reversal in phas…
Recombination of H3+ Ions in the Afterglow of a He-Ar-H2 Plasma
J. Glosik, I. Korolov, R. Plasil +7
Recombination of H3+ with electrons was studied in a low temperature plasma in helium. The plasma recombination rate is driven by two body, H3+ + e, and three-body, H3+ + e + He, p…
The degenerate Fermi gas with renormalized density-dependent interactions in the K harmonic approximation
Seth T. Rittenhouse, Chris H. Greene
We present a simple implementation of a density-dependent, zero-range interactions in a degenerate Fermi gas described in hyperspherical coordinates. The method produces a 1D effec…
Magneto-electrostatic trapping of ground state OH molecules
Brian C. Sawyer, Benjamin L. Lev, Eric R. Hudson +4
We report the magnetic confinement of neutral, ground state hydroxyl radicals (OH) at a density of cm and temperature of 30 mK. An adjustable elect…
