On these pages you find information about my past and present research activities in mathematical physics. Almost all of my work deals with quantum mechanics, a theory which appears to remain `forever young.'
My academic home is the Department of Mathematics at the University of York, England, where I research and teach as a Reader in Mathematical Physics.
I am interested in phenomena, concepts, and applications of non-relativistic quantum theory. In recent years, I have been publishing in quantum information and PT symmetry.
Earlier on, I have contributed to quantum state reconstruction for spin systems and to quantum chaos, more specifically to the question of defining integrability for quantum systems.
Wilkinson and I study the
properties of mutually
unbiased bases in spaces of infinite
dimensions, that is, mutually
unbiased bases for continuous
variables. I also collaborate with Ingemar Bengtsson and Stephen
Brierley on mutually unbiased bases in finite-dimensional
With Hans R Jauslin from the Université de Bourgogne, France, I share a longstanding interest in quantum systems exhibiting rigorously chaotic dynamics.
Amiet from the Université de Neuchâtel, Switzerland, was
alive, we would continue to write papers on state reconstruction and
Dan McNulty currently studies the role of mutually unbiased product bases in dimension six as well as mutually unbiased bases for continuous variables.
Spiros Kechrimparis joined our group in early 2012. At present he is interested in uncertaintly relations for sets of complementary variables.
