Jason Leonard – författare

Leonard’s story starts as rugby started – in the amateur days, when the Cockney Carpenter began playing for Barking and Saracens in the days before multi-million pound business owners and sponsorship deals. His big break came when he was invited to join the England squad for their tour to Argentina in 1990 and has been capped 100 times.It was a tour that precipitated one of the greatest periods in the history of the British game, and Leonard provides a compelling insight into life behind the international scenes with England and the Lions, as well as the domestic game through his time at Saracens and Harlequins.Once told that he would never walk again after undergoing life-saving surgery on his neck, Leonard describes the torment he went through during this period – both physical and financial – and how he fought against all the odds to re-establish himself on the international stage. With 100 Test caps won to date, and a career in rugby union spanning two decades, there is no more experienced player in the modern game.Leonard has plenty to tell about the people he has met during his career – Rob Andrew, Will Carling, Lawrence Dallaglio, Brian Moore, Dick Best and Clive Woodward all feature – and with nicknames like 'The Fun Bus' and 'The Scourge of the Barking Barmaids' the stories are as colourful and controversial as the man himself.All is revealed in this fascinating portrait of an English rugby legend who also reflects upon England's 2002 Six Nations campaign, his hopes for his international future and a tough year for Quins.

This thesis presents results crucial to the emerging field of indirect excitons. These specially designed quasiparticles give the unique opportunity to study fundamental properties of quantum degenerate Bose gases in semiconductors. Furthermore, indirect excitons allow for the creation of novel optoelectronic devices where excitons are used in place of electrons. Excitonic devices are explored for the development of advanced signal processing seamlessly coupled with optical communication.The thesis presents and describes the author's imaging experiments that led to the discovery of spin transport of excitons. The many firsts presented herein include the first studies of an excitonic conveyer, leading to the discovery of the dynamical localization-delocalization transition for excitons, and the first excitonic ramp and excitonic diode with no energy-dissipating voltage gradient.
