Professor Teunis (Tony) C. Dorlas | |

Tony Dorlas was born in Groningen, the Netherlands, in 1955.
At an early age he became interested in electronics, but soon
discovered that in order to understand it better he had to study
more mathematics and physics than was being taught at school.
His uncle then gave him an old book on differential and integral
calculus by H. A. Lorentz, which he possessed. This book he studied
with great interest and it made him change his mind about becoming an
electronics engineer. He entered the University of Groningen to study
Mathematics and Physics and graduated in both subjects, after which he
started working on a Ph.D. under Prof. Nico Hugenholtz. During this time
he gave a series of lectures on Constructive Quantum Field Theory and
prepared a set of notes (in Dutch) about this subject. His Ph.D. thesis
is on a related subject and is entitled He then moved to Dublin, to work as a Scholar (postdoc) at the Dublin
Institute for Advanced Studies, where he worked with Prof. John Lewis and
Prof. Joe Pule on a variety of models of a boson gas. In this work it was
shown that the phenomenon of Bose-Einstein condensation, which is now a very
popular subject due to the experimental observation of the effect in 1995,
is very subtle and depends on details of the interaction potential. A summary
of this work can be found in It also led to the solution of an old problem: a rigorous proof of the
Yang-Yang solution for the thermodynamics of the nonlinear Schroedinger model.
This model is exactly soluble with the help of the Bethe Ansatz, which means
that one can determine its eigenvalues and eigenfunctions exactly by means of
an initial guess. The problem of the completeness of these eigenfunctions was
left open, however. This problem was later also solved, after a position as
Lecturer in the Mathematics Department of University College of Swansea had
been taken up in 1989. The main paper about this work,
From 1995 until 1998 he also supervised a Ph. D. student,
Janak R. Wedagedera from Sri Lanka, on the subject of spin glasses and
error-correcting codes. This was inspired by a claim of N. Sourlas that spin
glasses could be used to construct a code that approximates Shannon's upper
bound on the rate of faithful transmission of information. In their
In the years 1993 until 1995 lecture courses were given on Statistical
Mechanics from a Large Deviation Theory point of view. These were
generally well-received and subsequently written up in a textbook entitled
In 1999 he accepted a Senior Professorship position at the Dublin Institute for Advanced Studies which he took up in January 2000. After a long process of moving to Dublin, he is now working on a new problem concerning Anderson localisation in collaboration with Joe Pule, and he is giving a set of lectures on Quantum Computing for Trinity students, but open to all. He has also continued research on spin glasses and possible connections with error-correcting codes, in particular in connection with quantum computing, together with Mark Dukes. |
