Kondo effect in electromigrated gold break junctions.

Nano letters

Houck AA, Labaziewicz J, Chan EK, Folk JA, Chuang IL.
PMID: 16159205
Nano Lett. 2005 Sep;5(9):1685-8. doi: 10.1021/nl050799i.

We present gate-dependent transport measurements of Kondo impurities in bare gold break junctions, generated with high yield using an electromigration process that is actively controlled. Thirty percent of measured devices show zero-bias conductance peaks. Temperature dependence suggests Kondo temperatures...

Limitations on the Persistence of Iminoxyls: Isolation of tert-Butyl 1,1-Diethylpropyl Ketiminoxyl and Related Radicals.

The Journal of organic chemistry

Eisenhauer BM, Wang M, Labaziewicz H, Ngo M, Mendenhall GD.
PMID: 11671509
J Org Chem. 1997 Apr 04;62(7):2050-2053. doi: 10.1021/jo962136e.

A series of iminoxyl radicals of the general formula R(C=NO(*))R(1), with R and R(1) usually tertiary, was synthesized in a search for radicals of increased persistence. Three new radicals were isolated as blue liquids: Et(3)C(C=NO(*))Bu-t (1), t-C(5)H(11)(C=NO(*))Bu-t (2), and...

Compact, filtered diode laser system for precision spectroscopy.

Optics letters

Labaziewicz J, Richerme P, Brown KR, Chuang IL, Hayasaka K.
PMID: 17392925
Opt Lett. 2007 Mar 01;32(5):572-4. doi: 10.1364/ol.32.000572.

Stable, narrow-linewidth optical sources are necessary in modern atomic physics. An appealing approach to achieving approximately 10 kHz frequency stability is optical feedback. We have designed a compact external cavity diode laser with optical feedback to a filter cavity...

Temperature dependence of electric field noise above gold surfaces.

Physical review letters

Labaziewicz J, Ge Y, Leibrandt DR, Wang SX, Shewmon R, Chuang IL.
PMID: 18999810
Phys Rev Lett. 2008 Oct 31;101(18):180602. doi: 10.1103/PhysRevLett.101.180602. Epub 2008 Oct 30.

Electric field noise from fluctuating patch potentials is a significant problem for a broad range of precision experiments, including trapped ion quantum computation and single spin detection. Recent results demonstrated strong suppression of this noise by cryogenic cooling, suggesting...

Kondo effect in the presence of magnetic impurities.

Physical review letters

Heersche HB, de Groot Z, Folk JA, Kouwenhoven LP, van der Zant HS, Houck AA, Labaziewicz J, Chuang IL.
PMID: 16486511
Phys Rev Lett. 2006 Jan 13;96(1):017205. doi: 10.1103/PhysRevLett.96.017205. Epub 2006 Jan 10.

We measure transport through gold grain quantum dots fabricated using electromigration, with magnetic impurities in the leads. A Kondo interaction is observed between dot and leads, but the presence of magnetic impurities results in a gate-dependent zero-bias conductance peak...

Suppression of heating rates in cryogenic surface-electrode ion traps.

Physical review letters

Labaziewicz J, Ge Y, Antohi P, Leibrandt D, Brown KR, Chuang IL.
PMID: 18232755
Phys Rev Lett. 2008 Jan 11;100(1):013001. doi: 10.1103/PhysRevLett.100.013001. Epub 2008 Jan 10.

Dense arrays of trapped ions provide one way of scaling up ion trap quantum information processing. However, miniaturization of ion traps is currently limited by sharply increasing motional state decoherence at sub-100 mum ion-electrode distances. We characterize heating rates...

Cryogenic ion trapping systems with surface-electrode traps.

The Review of scientific instruments

Antohi PB, Schuster D, Akselrod GM, Labaziewicz J, Ge Y, Lin Z, Bakr WS, Chuang IL.
PMID: 19191425
Rev Sci Instrum. 2009 Jan;80(1):013103. doi: 10.1063/1.3058605.

We present two simple cryogenic rf ion trap systems in which cryogenic temperatures and ultra high vacuum pressures can be reached in as little as 12 h. The ion traps are operated either in a liquid helium bath cryostat...

Cavity sideband cooling of a single trapped ion.

Physical review letters

Leibrandt DR, Labaziewicz J, Vuletić V, Chuang IL.
PMID: 19792300
Phys Rev Lett. 2009 Sep 04;103(10):103001. doi: 10.1103/PhysRevLett.103.103001. Epub 2009 Aug 31.

We report a demonstration and quantitative characterization of one-dimensional cavity cooling of a single trapped (88)Sr(+) ion in the resolved-sideband regime. We measure the spectrum of cavity transitions, the rates of cavity heating and cooling, and the steady-state cooling...
