Measuring impurity-induced shifts in Coulomb crystallization
Mingyao Xu, Aaron A. Smith, Leonid Prokhorov +2
We report a laboratory measurement of how impurities shift Coulomb crystallization in a strongly interacting ionic system. This is achieved by using laser cooled Ca crystals do…
Design and sensitivity of a 6-axis seismometer for gravitational wave observatories
Leonid Prokhorov, Sam Cooper, Amit Singh Ubhi +13
We present the design, control system, and noise analysis of a 6-axis seismometer comprising a mass suspended by a single fused silica fibre. We utilise custom-made, compact Michel…
Active platform stabilisation with a 6D seismometer
Amit Singh Ubhi, Leonid Prokhorov, Sam Cooper +9
We demonstrate the control scheme of an active platform with a six degree of freedom (6D) seismometer. The inertial sensor simultaneously measures translational and tilt degrees of…
Reducing controls noise in gravitational wave detectors with interferometric local damping of suspended optics
J van Dongen, L Prokhorov, S J Cooper +15
Control noise is a limiting factor in the low-frequency performance of the LIGO gravitational wave detectors. In this paper we model the effects of using new sensors called HoQIs t…
Measuring the stability of fundamental constants with a network of clocks
G. Barontini, L. Blackburn, V. Boyer +41
The detection of variations of fundamental constants of the Standard Model would provide us with compelling evidence of new physics, and could lift the veil on the nature of dark m…
QSNET, a network of clocks for measuring the stability of fundamental constants
G. Barontini, V. Boyer, X. Calmet +19
The QSNET consortium is building a UK network of next-generation atomic and molecular clocks that will achieve unprecedented sensitivity in testing variations of the fine structure…
