High-energy astrophysical neutrinos: testing ground for new physics
Time: 2:30 pm
Place: 5280 Chamberlin hall
Speaker: Mauricio Bustamante, Center for Cosmology and AstroParticle Physics (CCAPP), The Ohio State University
Abstract: High-energy astrophysical neutrinos, recently discovered by IceCube, are fertile ground to test for the presence of new physics. We can look for it at previously unexplored energies -- from tens of TeV to a few PeV, far beyond the reach of laboratory experiments. Due to cosmological-scale baselines -- Mpc to Gpc -- tiny new-physics effects, otherwise unobservable, could, by accumulation, become detectable. These include neutrino decay, violation of fundamental symmetries, and novel neutrino-neutrino interactions. I will show that the spectral features and flavor composition of neutrinos can reveal the presence and type of new physics. I will give special attention to neutrino decay. Present-day data are already sensitive to some models. More statistics, improvements in detection techniques, and detector upgrades will only enhance the sensitivity.

R. G. Herb Condensed Matter Seminar
Atomic and nanoscale donor devices in silicon: Progress towards fabrication and characterisation
Time: 10:00 am
Place: 5310 Chamberlin
Speaker: Dr. Neil Curson , University College London
Abstract: Donors in silicon are seen as good candidates for quantum information processing (QIP) applications due to the long spin lifetimes of their valance electrons and nuclei. I will report on our progress towards fabrication and characterisation of atomic and nanoscale devices based on donors in silicon. We have identified the precise atomic positions of buried neutral arsenic (As) donors below a hydrogen-passivated silicon surface using a combination of scanning tunnelling microscopy (STM) and density functional theory (DFT) studies [1,2]. We have also used scanning microwave microscopy (SMM) to image and electronically characterize patterned phosphorus nanostructures fabricated via scanning tunneling microscope-based lithography. The SMM measurements, which are completely non-destructive and sensitive to as few as 7000 sub-surface P atoms, yield electrical and geometric properties in agreement with those obtained from electrical transport and secondary ion mass spectroscopy (SIMS) for un-patterned phosphorus δ-layers. The ability to determine depth and electrical characteristics of buried P nanostructures leads the way towards 3D imaging of nanoscale electrical devices.<br>
