Reactions of Acetonitrile with Trapped, Translationally Cold Acetylene Cations
O. A. Krohn, K. J. Catani, S. P. Sundar +3
The reaction of the acetylene cation (C2H2+) with acetonitrile (CH3CN) is measured in a linear Paul ion trap coupled to a time-of-flight mass spectrometer. C2H2+ and CH3CN are both…
60 Gbps real-time wireless communications at 300 GHz carrier using a Kerr microcomb
Brendan M. Heffernan, Yuma Kawamoto, Keisuke Maekawa +6
Future wireless communication infrastructure will rely on terahertz systems that can support an increasing demand for large-bandwidth, ultra-fast wireless data transfer. In order t…
Dissipative Kerr soliton photonic terahertz oscillator referenced to a molecule
James Greenberg, Brendan M. Heffernan, Tomohiro Tetsumoto +1
Controlling the coherence between light and matter has enabled the radiation of electromagnetic waves with spectral purity and stability that defines the Système International (SI)…
Exceeding octave tunable Terahertz waves with zepto-second level timing noise
Rubab Amin, James Greenberg, Brendan Heffernan +2
Spectral purity of any millimeter wave (mmW) source is of the utmost interest in low-noise applications. Optical synthesis via photomixing is an attractive source for such mmWs, wh…
Photonic Generation of Millimeter-Waves Disciplined by Molecular Rotational Spectroscopy
James Greenberg, Rubab Amin, Brendan M. Heffernan +1
Optical generation of millimeter-waves (mm-wave) is made possible by an optical heterodyne of two diode lasers on a uni-traveling-carrier photodiode (UTC-PD). We utilized this tech…
Isotope-specific reactions of acetonitrile (CH3CN) with trapped, translationally cold CCl+
Olivia A. Krohn, Katherine J. Catani, James Greenberg +3
The gas-phase reaction of CCl+ with acetonitrile (CH3CN) is studied using a linear Paul ion trap coupled to a time-of-flight mass spectrometer. This work builds on a previous study…
Translationally cold trapped CCl+ reactions with acetylene (C2H2)
Katherine J. Catani, James Greenberg, Benjamin V. Saarel +1
Ion-neutral chemical reactions are important in several areas of chemistry, including in some regions of the interstellar medium, planetary atmospheres, and comets. Reactions of CC…
Quantum-State-Specific Reaction Rate Measurements for the Photo-induced Reaction Ca + O CaO + O
Philipp C. Schmid, Mikhail I. Miller, James Greenberg +3
Atoms and molecules often react at different rates depending on their internal quantum states. Thus, controlling which internal states are populated can be used to manipulate the r…
High resolution ion trap time-of-flight mass spectrometer for cold trapped ion experiments
Philipp C. Schmid, James Greenberg, Mikhail I. Miller +2
Trapping molecular ions that have been sympathetically cooled with laser-cooled atomic ions is a useful platform for exploring cold ion chemistry. We designed and characterized a n…
