Electromagnetic properties of terbium gallium garnet at millikelvin temperatures and single photon energy
Nikita Kostylev, Maxim Goryachev, Pavel Bushev +1
Electromagnetic properties of single crystal terbium gallium garnet (TGG) are characterised from room down to millikelvin temperatures using the whispering gallery mode method. Mic…
Determination of Low Loss in Isotopically Pure Single Crystal Si at Low Temperatures and Single Microwave Photon Energy
Nikita Kostylev, Maxim Goryachev, Andrey D. Bulanov +2
The low dielectric losses of an isotropically pure single crystal Si sample were determined at a temperature of 20 mK and at powers equivalent to that of a single photon. Wh…
A 3D Printed Superconducting Aluminium Microwave Cavity
Daniel L. Creedon, Maxim Goryachev, Nikita Kostylev +2
3D printing of plastics, ceramics, and metals has existed for several decades and has revolutionized many areas of manufacturing and science. Printing of metals in particular has f…
Ultra-High Cooperativity Interactions between Magnons and Resonant Photons in a YIG sphere
Jeremy Bourhill, Nikita Kostylev, Maxim Goryachev +2
Resonant photon modes of a 5mm diameter YIG sphere loaded in a cylindrical cavity in the 10-30GHz frequency range are characterised as a function of applied DC magnetic field at mi…
Superstrong Coupling of a Microwave Cavity to YIG Magnons
Nikita Kostylev, Maxim Goryachev, Michael E. Tobar
Multiple-post reentrant 3D lumped cavity modes have been realized to design the concept of discrete Whispering Gallery and Fabry-Perot-like Modes for multimode microwave Quantum El…
Single Photon Level Study of Microwave Properties of Lithium Niobate at milli-Kelvin Temperatures
Maxim Goryachev, Nikita Kostylev, Michael E. Tobar
Properties of doped and natural impurities in Lithium Niobate single crystals are studied using the Whispering Gallery Mode method at low temperatures as a function of magnetic fie…
