Infrared Spectroscopy and Photochemistry of Aromatic Nitriles in Para-Hydrogen Matrices
Sam McGrath, Vincent J. Esposito, Linshan Zeng +6
Motivated by recent detections of several aromatic nitriles in Taurus Molecular Cloud-1, we report laboratory and theoretical investigations of the vibrational spectroscopy and pho…
On the origin of infrared bands attributed to tryptophan in Spitzer observations of IC 348
Aditya Dhariwal, Thomas H. Speak, Linshan Zeng +12
Infrared emission features toward interstellar gas of the IC 348 star cluster in Perseus have been recently proposed to originate from the amino acid tryptophan. The assignment was…
Demonstration of magnetically silent optically pumped magnetometers for the TUCAN electric dipole moment experiment
Wolfgang Klassen, Shomi Ahmed, Kiera Pond Grehan +9
We report the performance of a magnetically silent optically pumped cesium magnetometer with a statistical sensitivity of 3.5 pT/rtHz at 1~Hz and a stability of 90 fT over 150 seco…
The Precision nEDM Measurement with UltraCold Neutrons at TRIUMF
Ryohei Matsumiya, Hiroaki Akatsuka, Chris P. Bidinosti +45
The TRIUMF Ultra-Cold Advanced Neutron (TUCAN) collaboration aims at a precision neutron electric dipole moment (nEDM) measurement with an uncertainty of $10^{-27}\,e\cdot\mathrm{c…
Penning collisions between supersonically expanded metastable helium atoms and laser-cooled lithium atoms
Jonas Grzesiak, Takamasa Momose, Frank Stienkemeier +2
We describe an experimental setup comprised of a discharge source for supersonic beams of metastable helium atoms and a magneto-optical trap (MOT) for ultracold lithium atoms that…
Production of rotationally cold methyl radicals in pulsed supersonic beams
Jonas Grzesiak, Manish Vashishta, Pavle Djuricanin +4
We present a comparison of two technically distinct methods for the generation of rotationally cold, pulsed supersonic beams of methyl radicals (CH3): a plate discharge source oper…
A Stern-Gerlach separator of chiral enantiomers based on the Casimir-Polder potential
Fumika Suzuki, Takamasa Momose, Stefan Yoshi Buhmann
We propose a method to separate enantiomers using parity violation in the Casimir-Polder potential between chiral mirrors and chiral molecules. The proposed setup involves a molecu…
Magnetic Trapping of Cold Methyl Radicals
Yang Liu, Manish Vashishta, Pavle Djuricanin +5
We have demonstrated that a supersonic beam of methyl radicals (CH) in the ground rotational state of both and species has been slowed down to standstill with a…
Anapole moment of a chiral molecule revisited
Takeshi Fukuyama, Takamasa Momose, Daisuke Nomura
Parity violation in a chiral, four-atom molecule is discussed. Given the geometrical positions of the four atoms, we calculate the anapole moment of it. This problem was first disc…
Controllable quantum spin glasses with magnetic impurities embedded in quantum solids
Mikhail Lemeshko, Norman Y. Yao, Alexey V. Gorshkov +4
Magnetic impurities embedded in inert solids can exhibit long coherence times and interact with one another via their intrinsic anisotropic dipolar interaction. We argue that, as a…
Excitation and emission spectra of rubidium in rare-gas thin-films
Ilja Gerhardt, Brian Sin, Takamasa Momose
To understand the optical properties of atoms in solid state matrices, the absorption, excitation and emission spectra of rubidium doped thin-films of argon, krypton and xenon were…
Intense pulsed helium droplet beams
Mikhail N. Slipchenko, Susumu Kuma, Takamasa Momose +1
Pulsed (30 - 100 microseconds) nozzle beams have been used to generate helium droplets (<N> = 10^4-10^5). The dependence of the beam intensity and the mean droplet size on the sour…
