Breakthrough study on exploring open quantum systems forms new theory
A collaboration of research between Durham University’s Dr. Nikitas Gidopoulos, formerly of ISIS at the Rutherford Appleton Laboratory, and Dario Calvani, Alessandro Cuccoli and Paola Verrucchi (from Italy’s University of Florence, National Institute for Nuclear Physics-INFN, and National Research Council-CNR) has been published in a major US scientific journal.
The ‘Proceedings of the National Academy of Sciences’ reports how this breakthrough study has brought together two diametrically different approaches to exploring open quantum systems, and formed the underlying theory. This includes shedding light on the understanding of coherence between quantum systems or a quantum system and its environment.
Defined by Feynman as “a part of the Universe”, this ‘open system’ has until now been largely untapped, disguised by the rest of the system around it, the ‘environment’. However the researchers have found that the behaviour of the principle system (focus of attention) depends, is influenced and often driven by its surrounding environment and the links with it (correlations).
The purpose of the paper was to propose a way of describing this link more precisely. “Looking at popular science texts, one usually reads that quantum mechanics is the part of physics that describes the behaviour of very small things, like atoms and subatomic particles”, says Dr Gidopoulos, “but it’s not just very small things that have a deep quantum mechanical origin, but particles with much larger masses whose effects we experience daily and often take them granted as classical”.
Left: In this analogy the open system is the bee and the environment the flowers: details of the bees evidently emerge but we can no longer understand some aspects of their behaviour, such as the relation between their being still in a point and the fact that there is a flower underneath. Whereas the bottom image shows that a theoretical approach to open quantum systems is possible, that corresponds to a representation where every single detail of the bees image is kept, together with the relevant correlations between their behaviour and the structure of the flowering field they are flying upon.
The team have applied these conceptual tools to analyse a paradigmatic example in the study of open quantum systems, with a view to studying more realistic/complicated problems and most importantly to study the dynamics of open systems in relation to their environment.
This includes, for example, applying a magnetic field to a spin, an effect once taken as classical, whereas now the team have found how the correlations of the underlying quantum entanglement between system and environment manifest.
So what does this mean? Well, quantum correlations or entanglement may be used in order to control/drive a quantum system that is influenced by its environment (quantum information transfer/quantum transport.) Also, these conceptual tools have the potential to become widely used as a theoretical formalism/methodology to study open quantum systems.

Surviving Warsaw 1939-1945: Untold Stories of Occupation and the Ghetto
Dr. Marek Szablewski will give a talk at 14:15pm on Sunday 11 November atHolgate House, Grey College. Dr Marek Szablewski, a Durham university physics lecturer born and brought up in Sheffield and has recently returned from an eight-week Winston Churchill Travelling Fellowship (www.wcmt.org.uk) to Europe. The aim of his Fellowship was to research his hidden Polish family history and the journey that brought his parents to Yorkshire after World War Two.
Durham and Oxford join forces in new approach to Synthesising Superconductors
A team of scientists from Oxford and Durham Universities, in collaboration with researcher at the ISIS facility, Oxfordshire
have demonstrated that a new approach to synthesising superconductors results in a dramatic improvement in their useful properties.
Doctoral Supervision Award to member of Staff
Peter Hatton has been awarded one of the University Doctoral Supervision awards in 2012. In his career at both Edinburgh and Durham he has helped over twenty doctoral research students complete their PhD’s, twelve of who are still active researchers and academics, including eight Professors. In many cases he continues to work with his ex-students many years after they left Durham.
