Prospects for application of ultracold Sr$_2$ molecules in precision measurements (2008)

Kotochigova, S., Zelevinsky, T., Ye, Jun

Precision measurements with ultracold molecules require development of robust and sensitive techniques to produce and interrogate the molecules. With this goal, we theoretically analyze factors that...

Sr lattice clock at 1x10^{-16} fractional uncertainty by remote optical evaluation with a Ca clock (2008)

Ludlow, A. D., Zelevinsky, T., Campbell, G. K., Blatt, S., Boyd, M. M., ...

Optical atomic clocks promise timekeeping at the highest precision and accuracy, owing to their high operating frequencies. Rigorous evaluations of these clocks require direct comparisons between...

New Limits on Coupling of Fundamental Constants to Gravity Using $^{87}$Sr Optical Lattice Clocks (2008)

Blatt, S., Ludlow, A. D., Campbell, G. K., Thomsen, J. W., Zelevinsky, T., Boyd, M. M., ...

The $^1\mathrm{S}_0$-$^3\mathrm{P}_0$ clock transition frequency $\nu_\text{Sr}$ in neutral $^{87}$Sr has been measured relative to the Cs standard by three independent laboratories in Boulder,...

New limits on coupling of fundamental constants to gravity using Sr-87 optical lattice clocks (2008)

Blatt, S, Ludlow, A, Thomsen, J, Zelevinsky, T, ...

Precision Test of Mass Ratio Variations with Lattice-Confined Ultracold Molecules (2007)

Zelevinsky, T., Kotochigova, S., Ye, J.

We propose a precision measurement of time variations of the proton-electron mass ratio using ultracold molecules in an optical lattice. Vibrational energy intervals are sensitive to changes of the...

Narrow Line Photoassociation in an Optical Lattice (2006)

Zelevinsky, T., Boyd, M. M., Ludlow, A. D., Ido, T., Ye, J., Ciurylo, R., ...

With ultracold $^{88}$Sr in a 1D magic wavelength optical lattice, we performed narrow line photoassociation spectroscopy near the $^1$S$_0 - ^3$P$_1$ intercombination transition. Nine least-bound...

Systematic study of the $^{87}$Sr clock transition in an optical lattice (2005)

Ludlow, Andrew D., Boyd, Martin M., Zelevinsky, T., Foreman, Seth M., Blatt, Sebastian, Notcutt, Mark, ...

With ultracold $^{87}$Sr confined in a magic wavelength optical lattice, we present the most precise study (2.8 Hz statistical uncertainty) to-date of the $^1S_0$ - $^3P_0$ optical clock transition...

Light-Pressure-Induced Shifts of 2^3S(J=1) = 2^3P(J=0,1,2) Helium Lines in a Vapor Cell and Implications for the Fine Structure Constant Measurement (2004)

Zelevinsky, T.

This paper has been temporarily withdrawn by the authors. In the process of 4He 2P fine structure measurement in a vapor cell, highly nonlinear dependences of 2S_1 - 2P_J intervals on helium density...

Nonlinear Variation of Light-Pressure-Induced Multilevel Atomic Line Shifts with Vapor Pressure in Helium Spectroscopy (2004)

Zelevinsky, T.

This paper has been temporarily withdrawn. Highly nonlinear dependences of 4He 2^3S - 2^3P lines on pressure were observed in vapor cell saturation spectroscopy. Line shifts agree with those expected...

Large-Angle, Single-Order, One and Two-Dimensional Atomic Interferometry for Creation of Nanostructures (2000)

Shahriar, M. S., Zelevinsky, T., Hemmer, P. R.

We have shown via explicit analysis as well as numerical simulation the design of two large angle interferometers employing two-photon pulses. The first one uses the technique of adiabatic following...
