The Fritz London Memorial Prize

The Fritz London Prize was created to recognize scientists who made outstanding contributions to the advances of the field of Low Temperature Physics. It is traditionally awarded in the first session of the International Low Temperature Conference(LT), which is sponsored by the IUPAP (International Union of Pure and Applied Physics) and was first awarded in 1957.  The London Prize was first funded by grants from the A.D. Little Company that made the Collins helium liquefiers. The funding on a regular basis dates back to 1972 when John Bardeen gave his portion of the Nobel Prize to Duke University for an endowment, called "the Fritz London Fund". This was to provide support for the annual Fritz London lecture and for the London Prize. In 1994, a second endowment was created at Duke University from a) the balance of funds remaining from the LT20 Conference in Oregon, remitted by Russell Donnelly, and b) a gift from Horst Meyer. This second endowment is called "Fritz London Prize endowment" and is solely intended for the London Prize. Further gifts to this endowment were made in 2000, 2006 and 2009 by the Organizers of the LT22, LT24 and LT25 Conferences in Helsinki (Finland), Orlando (Florida, USA) and Amsterdam (The Netherlands). Furthermore Oxford Instruments Inc. in Abingdon, UK, made generous gifts in cash for all the London prizes awarded since 1996.

The 2011 Simon Memorial Prize


The 2011 Simon Memorial Prize is awarded to Sergey V. Iordanskii and Nikolai B. Kopnin "For their calculations and predictions of the fundamental forces acting on quantised vortices in superfluids, superconductors and other ordered systems:  The Iordanskii force and the Kopnin force"

A vortex moving in a classical liquid experiences the famous Magnus force which acts between the liquid and the vortex. However, superfluids and superconductors differ from classical fluids and introduce new forces that were first understood by Kopnin and Iordanskii. This physics was later understood to have much wider applicability.

The Iordanskii force arises in both Bose and Fermi superfluids and has a universal form. Its value is fundamental, being determined by the vortex winding number, the density of the normal component and the vortex velocity relative to the normal component. The universality arises from the topological nature, it is the result of the Aharonov-Bohm effect experienced by quasiparticles that are scattered by the vortex. A similar effect occurs in cosmology for matter scattering on spinning cosmic strings.

The Kopnin force appears in BCS systems - superconductors and fermionic superfluids. The Kopnin force is also fundamental. It has the same origin as the Adler-Bell-Jackiw anomaly in relativistic quantum field theories. In the Standard Model of particle physics the anomaly leads to non-conservation of baryonic charge and as a result to an excess of matter over anti-matter in our Universe. In superconductors and fermionic superfluids the same anomaly leads to the apparent non-conservation of momentum, which manifests as the Kopnin force.

The combined Iordanskii and Kopnin forces are also important in many areas of physics. In superconductors, the motion of quantized Abrikosov  vortices is the only significant source of dissipation, making the Iordanskii and Kopnin forces of considerable technological importance and in superfluids, the predictions of Iordanskii and Kopnin have led to the discovery of new phenomena. The Iordanskii and Kopnin forces are essential to the understanding of vortex dynamics in neutron and proton superfluids and in the coloursuperconducting quark matter that may exist in the core of a neutron star.
