The past month has seen a number of people leave and start at the London Centre of Nanotechnology (LCN).
Dr Meera Parish joined LCN in October 2011 as a Lecturer in Theoretical Physics. She grew up in Australia and obtained her Bachelor of Science (Honours) degree from the Australian National University. She subsequently moved to Cambridge and completed a PhD in theoretical condensed matter physics at the Cavendish Laboratory. To further broaden her horizons, she then spent some time as a postdoctoral fellow in the Princeton Center for Theoretical Science at Princeton University, before returning to Cambridge in 2009 as an EPSRC Career Acceleration Fellow.
Her research spans the fields of strongly correlated electron systems and ultracold atomic gases. She has previously worked on the properties of fermionic superfluids and the magnetotransport in disordered conductors. Her current aim is to investigate quantum many-body systems at the interface between ultracold atomic gases and unconventional superconductors.
Professor Andrew Green joins the LCN from the University of St Andrews. His research is in the broad area of strongly correlated electron systems. During his 8 years in Scotland a major theme of his research concerned quantum criticality - developing new tools to understand phase reconstruction at metallic quantum critical points, and pioneering the study of universal out-of-equilibrium behaviour at quantum criticality.
His research programme in LCN will continue to expand these directions forging some new links along the way. For example, the tools developed to understand phase reconstruction at quantum criticality suggest some interesting features of the nodal structure used in quantum Monte Carlo studies. There may also be deep connections between quantum criticality and gravity revealed by the so called AdS/ CFT correspondence discovered in strong theory - techniques that Andrew has recently used to study out-of-equilibrium quantum criticality.
Both strong correlations and out-of-equilibrium behaviour are at the edge of our understanding and can often confound theoretical expectations. Experimental guidance is essential to contain wild theoretical speculations - usually by suggesting a wilder, unimagined reality.
And finally, Professor Arokia Nathan leaves the LCN and we congratulate him on his appointment to the Chair of Photonic Systems and Displays in the Electrical Engineering Division of the Department of Engineering, University of Cambridge. Over the period of tenure at University College London, he has contributed significantly to both the research profile and operations at the LCN where he carried out pioneering research on nano-scale large area electronics, tackling risky, fundamental problems, for leading edge applications. His innovations in TFT integration and pixel architectures address the most challenging issues of TFT stability and lifetime, and his findings have profoundly influenced technology directions in design of flat panel systems. He also developed low temperature thin film silicon processes optimized at deposition temperatures safe for integration of transistors, image sensors, and solar cells on plastic substrates.
As one of the top TFT systems integration experts in the field, Prof. Nathan's contributions are documented in numerous peer-reviewed papers and conference proceedings, books, book chapters. He has also authored many patents, which form the basis of two spin-off companies he founded to commercialize technology on thin film transistor backplanes and driving algorithms for displays and bio-photonic systems. Besides his exceptional research scholarship, he is recognized as an academic leader with all-round strengths in graduate education and mentoring, and technical leadership. The LCN wishes Professor Nathan the very best in his future endeavours in his new post at Cambridge University.
