Large phonon time-of-flight fluctuations in expanding flat condensates of cold fermi gases
Da-Shin Lee, Chi-Yong Lin, Ray J. Rivers
We reexamine how quantum density fluctuations in condensates of ultra-cold fermi gases lead to fluctuations in phonon times-of-flight, an effect that increases as density is reduce…
Was Thebes Necessary? Contingency in Spatial Modelling
Tim S. Evans, Ray J. Rivers
When data is poor we resort to theory modelling. This is a two-step process. We have first to identify the appropriate type of model for the system under consideration and then to…
When are two fermions a simple boson? New Gross-Pitaevskii actions for cold Fermi condensates
Ray J. Rivers, D. A. Steer, Chi-Yong Lin +2
The BEC regime of a cold fermi gas is characterised by coupled atoms (dimers) which, superficially, look like elementary bosons. We examine how simply-bosonic they really are; firs…
Quantum stochastic behaviour in cold Fermi gases: Phonon propagation
En-Tsung Hsiang, Da-Shin Lee, Chi-Yong Lin +1
We examine the effect of quantum fluctuations in a tunable cold Fermi gas on the propagation of phonons. We show that these fluctuations can be interpreted as inducing a stochastic…
Gaussianity revisited: Exploring the Kibble-Zurek mechanism with superconducting rings
D. J. Weir, R. Monaco, V. P. Koshelets +2
In this paper we use spontaneous flux production in annular superconductors to shed light on the Kibble-Zurek scenario. In particular, we examine the effects of finite size and ext…
The role of Causality in Tunable Fermi Gas Condensates
Jen-Tsung Hsiang, Chi-Yong Lin, Da-Shin Lee +1
We develop a new formalism for the description of the condensates of cold Fermi atoms whose speed of sound can be tuned with the aid of a narrow Feshbach resonance. We use this to…
