Frequency-Temperature sensitivity reduction with optimized microwave Bragg resonators
Jean-Michel Le Floch, Christopher Murphy, John Gideon Hartnett +4
Dielectric resonators are employed to build state-of-the-art low-noise and high- stability oscillators operating at room and cryogenic temperatures. A resonator temperature coeffic…
Generalizing the Lorentz transformations
James M. Chappell, David L. Berkahn, Nicolangelo Iannella +3
In this paper we develop a framework allowing a natural extension of the Lorentz transformations. To begin, we show that by expanding conventional four-dimensional spacetime to eig…
Drift-compensated Low-noise Frequency Synthesis Based on a cryoCSO for the KRISS-F1
Myoung-Sun Heo, Sang Eon Park, Won-Kyu Lee +9
In this paper we report on the implementation and stability analysis of a drift-compensated frequency synthesizer from a cryogenic sapphire oscillator (CSO) designed for a Cs/Rb at…
A brief study of time
James M. Chappell, John G. Hartnett, Azhar Iqbal +2
Understanding the nature of time remains a key unsolved problem in science. Newton in the Principia asserted an absolute universal time that {\it `flows equably'}. Hamilton then pr…
The vector algebra war: a historical perspective
James M. Chappell, Azhar Iqbal, John G. Hartnett +1
There are a wide variety of different vector formalisms currently utilized in engineering and physics. For example, Gibbs' three-vectors, Minkowski four-vectors, complex spinors in…
A new derivation of the Minkowski metric
James M. Chappell, John G. Hartnett, Nicolangelo Iannella +3
The four dimensional spacetime continuum, as first conceived by Minkowski, has become the dominant framework within which to describe physical laws. In this paper, we show how this…
