Aggregate Frequency Width, Nuclear Hyperfine Coupling and Jahn-Teller Effect of Impurity Ion ESR in Dielectric Resonator at Millikelvin
M. A. Hosain, J. -M. Le Floch, J. Krupka +1
The impurity paramagnetic ion, substitutes in the single crystal lattice, this results in a elongated octahedron, the resulting measured g-factor…
Rigorous ESR spectroscopy of impurity ion with oxygen vacancy in ferroelectric crystal at 20 mK
M. A. Hosain, J-M. Le Floch, J. Krupka +1
Impurity ion electron spin resonance (ESR) spectroscopy using multiple dielectric modes in a dielectric resonator has been performed with a tuneable DC magnetic…
Can Traditional Terrestrial Applications of Gravity Gradiometry Rely Upon Quantum Technologies ? A Side View
Alexey V. Veryaskin, Michael E. Tobar
The era of practical terrestrial applications of gravity gradiometry begun in 1890 when Baron Lorand von Eötvös, a Hungarian nobleman and a talented physicist and engineer, invente…
Generation of Bimodal Solitons in a Sapphire Whispering Gallery Mode Maser at Millikelvin Temperatures
Catriona A. Thomson, Michael E. Tobar, Maxim Goryachev
We present experimental observations of bimodal solitons in a solid state three-level maser cooled to millikelvin temperatures. The maser is built on a highly dilute $\textrm{Fe}^{…
Broadband sensitivity improvement via coherent quantum feedback with PT symmetry
Xiang Li, Maxim Goryachev, Yiqiu Ma +4
A conventional resonant detector is often subject to a trade-off between bandwidth and peak sensitivity that can be traced back to quantum Cramer-Rao Bound. Anomalous dispersion ha…
Experimental Implementations of Cavity-Magnon Systems: from Ultra Strong Coupling to Applications in Precision Measurement
Graeme Flower, Maxim Goryachev, Jeremy Bourhill +1
Several experimental implementations of cavity-magnon systems are presented. First an Yttrium Iron Garnet (YIG) block is placed inside a re-entrant cavity where the resulting hybri…
