Varying alpha, blinding, and bias in existing measurements

Chung-Chi Lee, John K. Webb, Robert F. Carswell +3

The high resolution spectrograph ESPRESSO on the VLT allows measurements of fundamental constants at unprecedented precision and hence enables tests for spacetime variations predic…

Measuring the fine structure constant on white dwarf surfaces; uncertainties from continuum placement variations

Chung-Chi Lee, John K. Webb, Darren Dougan +2

Searches for variations of fundamental constants require accurate measurement errors. There are several potential sources of errors and quantifying each one accurately is essential…

A limit on variations in the fine-structure constant from spectra of nearby Sun-like stars

Michael T. Murphy, Daniel A. Berke, Fan Liu +4

The fine structure constant, , sets the strength of the electromagnetic force. The Standard Model of particle physics provides no explanation for its value, which could potentia…

Space-time variation of the s and c quark masses

V. V. Flambaum, P. Munro-Laylim

Space-time variation of fundamental physical constants in expanding Universe is predicted by a number of popular models. The masses of second generation quarks are larger than firs…

Searching for scalar field dark matter with hyperfine transitions in alkali atoms

V. V. Flambaum, A. J. Mansour, I. B. Samsonov +1

Fundamental constants such as masses and coupling constants of elementary particles can have small temporal and spatial variations in the scalar field dark matter model. These vari…

Probing Supersymmetry Breaking Scale with Atomic Clocks

Victor V. Flambaum, Xuewen Liu, Igor Samsonov +2

The supersymmetry (SUSY) breaking mechanism generally predicts the existence of the sgoldstinos, which can play the role of wave-like dark matter. Due to the ubiquitous coupling to…
