UCL Astrophysicists lead analysis of SPIRE results from Herschel telescope

UCL staff members and several research and postdoctoral fellows are involved in the analysis of imaging and spectroscopic data from the Herschel telescope. Physics and Astronomy are heavily involved in the analysis of the data from the SPIRE instrument and in particular are looking at the SPIRE spectrum of VY CMa. The early results have been featured in ESA, STFC and BBC articles. More...

Correlation-Dependent Coherent to Incoherent Transitions in Resonant Energy Transfer Dynamics

Quantum coherence can be protected through correlations:
In this work, Ahsan Nazir shows that fragile quantum coherences can even survive at elevated temperatures in the energy transfer process within a pair of nanoscale systems, provided strong correlations exist between the random fluctuations they naturally experience.

	Ice XV: A New Thermodynamically Stable Phase of Ice Scientists at UCL Physics and Astronomy, the London Centre for Nanotechnology and the University of Oxford have discovered another form of ice, ice XV, and in doing so have crossed one of the remaining frontiers in ice research. It was known that this phase must exist, but until now no-one had been able to make it. More...

Integral Relations for Three-Body Continuum States with the Adiabatic Expansion

In this paper we present a new method for extracting the scattering amplitude from a known wavefunction, based on two integral relations derived from the Kohn variational principle.

Thermochemical nanopatterning of organic semiconductors

Patterning of semiconducting polymers on surfaces is important for various applications in nanoelectronics and nanophotonics. However, many of the approaches to nanolithography that are used to pattern inorganic materials are too harsh for organic semiconductors, so research has focused on optical patterning and various soft lithographies. Surprisingly little attention has been paid to thermal, thermomechanical and thermochemical patterning.
