  • Evaluation of a Sr+ 88 Optical Clock with a Direct Measurement of the Blackbody Radiation Shift and Determination of the Clock Frequency 
    Steinel, M.; Shao, H.; Filzinger, M.; Lipphardt, B.; Brinkmann, M.; Didier, A.; Mehlstäubler, T. E.; Lindvall, T.; Peik, E.; Huntemann, N. (College Park, Md. : APS, 2023)
    We report on an evaluation of an optical clock that uses the S21/2→D25/2 transition of a single Sr+88 ion as the reference. In contrast to previous work, we estimate the effective temperature of the blackbody radiation ...
  • Quantum-Enhanced Advanced LIGO Detectors in the Era of Gravitational-Wave Astronomy 
    Tse, M.; Yu, H.; Kijbunchoo, N.; Fernandez-Galiana, A.; Dupej, P.; Barsotti, L.; Blair, C.D.; Brown, D.D.; Dwyer, S.E.; Effler, A.; et al.; Bode, N.; Booker, P.; Liu, J.; Meylahn, F.; Willke, B. (College Park, MD : American Physical Society, 2019)
    The Laser Interferometer Gravitational Wave Observatory (LIGO) has been directly detecting gravitational waves from compact binary mergers since 2015. We report on the first use of squeezed vacuum states in the direct ...
