Number fluctuations of a dipolar condensate: anisotropy and slow approach to the thermodynamic regime.

Physical review letters

Baillie D, Bisset RN, Ticknor C, Blakie PB.
PMID: 25615347
Phys Rev Lett. 2014 Dec 31;113(26):265301. doi: 10.1103/PhysRevLett.113.265301. Epub 2014 Dec 24.

We present a theory for the number fluctuations of a quasi-two-dimensional (quasi-2D) dipolar Bose-Einstein condensate measured with finite resolution cells. We show that when the dipoles are tilted to have a component parallel to the plane of the trap,...

Transport properties of an asymmetric mixture in the dense plasma regime.

Physical review. E

PMID: 27415378
Phys Rev E. 2016 Jun;93(6):063208. doi: 10.1103/PhysRevE.93.063208. Epub 2016 Jun 23.

We study how concentration changes ionic transport properties along isobars-isotherms for a mixture of hydrogen and silver, representative of turbulent layers relevant to inertial confinement fusion and astrophysics. Hydrogen will typically be fully ionized while silver will be only...

Ionization thresholds of small carbon clusters: tunable VUV experiments and theory.

Journal of the American Chemical Society

J Am Chem Soc. 2007 Aug 22;129(33):10229-43. doi: 10.1021/ja072526q. Epub 2007 Jul 27.

Small carbon clusters (Cn, n = 2-15) are produced in a molecular beam by pulsed laser vaporization and studied with vacuum ultraviolet (VUV) photoionization mass spectrometry. The required VUV radiation in the 8-12 eV range is provided by the...

Static and dynamic properties of multi-ionic plasma mixtures.

Physical review. E

Clérouin J, Arnault P, Gréa BJ, Guisset S, Vandenboomgaerde M, White AJ, Collins LA, Kress JD, Ticknor C.
PMID: 32289916
Phys Rev E. 2020 Mar;101(3):033207. doi: 10.1103/PhysRevE.101.033207.

Complex plasma mixtures with three or more components are often encountered in astrophysics or in inertial confinement fusion (ICF) experiments. For mixtures containing species with large differences in atomic number Z, the modeling needs to consider at the same...

Tuning p-wave interactions in an ultracold Fermi gas of atoms.

Physical review letters

Regal CA, Ticknor C, Bohn JL, Jin DS.
PMID: 12633351
Phys Rev Lett. 2003 Feb 07;90(5):053201. doi: 10.1103/PhysRevLett.90.053201. Epub 2003 Feb 05.

We have measured a p-wave Feshbach resonance in a single-component, ultracold Fermi gas of 40K atoms. We have used this resonance to enhance the normally suppressed p-wave collision cross section to values larger than the background s-wave cross section...

Creation of ultracold molecules from a Fermi gas of atoms.

PMID: 12840753
Nature. 2003 Jul 03;424(6944):47-50. doi: 10.1038/nature01738.

Following the realization of Bose-Einstein condensates in atomic gases, an experimental challenge is the production of molecular gases in the quantum regime. A promising approach is to create the molecular gas directly from an ultracold atomic gas; for example,...

Automated introduction platforms integrated with inductively coupled plasma optical emission spectroscopy (ICP-OES) systems are continuously being improved. Expanding on the introduction systems, a newly developed automated ion chromatography system was explored for performing rapid in-line separations coupled to ICP-OES...

Attosecond two-photon interferometry for doubly excited states of helium.

Feist J, Nagele S, Ticknor C, Schneider BI, Collins LA, Burgdörfer J.
PMID: 21929238
Phys Rev Lett. 2011 Aug 26;107(9):093005. doi: 10.1103/PhysRevLett.107.093005. Epub 2011 Aug 26.

We show that the correlation dynamics in coherently excited doubly excited resonances of helium can be followed in real time by two-photon interferometry. This approach promises to map the evolution of the two-electron wave packet onto experimentally easily accessible...

Photodissociation of noble metal-doped carbon clusters.

Noble metal carbide cluster cations (MC(n)(+), M = Cu, Au) are produced by laser vaporization in a pulsed molecular beam and detected with time-of-flight mass spectrometry. Copper favors the formation of carbides with an odd number of carbon atoms,...

We describe a method for evolving the projected Gross-Pitaevskii equation (PGPE) for an interacting Bose gas in a harmonic-oscillator potential, with the inclusion of a long-range dipolar interaction. The central difficulty in solving this equation is the requirement that...
