Evidence that rotons in helium II are interstitial atoms
Robert M Brady, Edward T Samulski, David H P Turban
Superfluid helium II contains excitations known as rotons. Their properties have been studied experimentally for more than 70 years but their structure is not fully understood. Fey…
Maxwell's fluid model of magnetism
Robert Brady, Ross Anderson
In 1861, Maxwell derived two of his equations of electromagnetism by modelling a magnetic line of force as a `molecular vortex' in a fluid-like medium. Later, in 1980, Berry and co…
The irrotational motion of a compressible inviscid fluid
Robert Brady
The irrotational motion of a compressible inviscid fluid is studied in the field of analogue gravity, where its metric is compared to that in general relativity, a fluid analogue o…
Why quantum computing is hard - and quantum cryptography is not provably secure
Ross Anderson, Robert Brady
Despite high hopes for quantum computation in the 1990s, progress in the past decade has been slow; we still cannot perform computation with more than about three qubits and are no…
