Events at Physics
Events on Thursday, September 30th, 2010
- R. G. Herb Condensed Matter Seminar
- Spin spirals in underdoped cuprates: theory and experiment
- Time: 10:00 am
- Place: 5310 Chamberlin
- Speaker: Oleg P. Sushkov, University of New South Wales
- Abstract: To shed light on generic physics of cuprate superconductors (doped Mott insulators) I discuss and relate the following issues:
1)Incommensurate spin ordering in LSCO and YBCO.
2)Difference and similarities between these compounds: disorder versus bilayer.
3)Quantum Critical and Lifshitz points in YBCO and LSCO.
4)Magnetic Quantum Oscillations in YBCO.
5)Recent MSR data.
- Host: Andrey Chubukov
- NPAC (Nuclear/Particle/Astro/Cosmo) Forum
- Fundamental Physics at Low Energies
- Time: 11:00 am
- Place: 4274 Chamberlin
- Speaker: Joerg Jaeckel, Durham University
- Abstract: Over the years we have accumulated a large number of indications for physics beyond the standard model. This new physics is often sought-after at high masses and energies. However, over recent years it has become increasingly clear that new physics can also appear at low energy, but extremely weak coupling. Experiments and observations at this `low energy frontier' therefore provide a powerful tool to gain insight into fundamental physics, which is complementary to accelerators.
- Host: Sonny Mantry
- Astronomy Colloquium
- Models of Wind-Driving Protostellar Disks
- Time: 3:30 pm
- Place: 4421 Sterling Hall Same Location
- Speaker: Seth Teitler, UW Astronomy Dept
- Abstract: TBD
- Department of Physics Special Seminar
- Dark Matter Searches with DM-Ice and CUORE
- Time: 4:00 pm
- Place: 2241 Chamberlin (cookies & coffee served at 3:30 p.m)
- Speaker: Reina Maruyama, University of Wisconsin at Madison
- Abstract: Observations from cosmology tell us that less than 4% of our Universe is comprised of ordinary visible matter, and that the rest is made of Dark Matter and Dark Energy. Much of our understanding of Dark Matter is inferred from astronomical and astrophysical observations. There are concerted efforts to study the properties of Dark Matter by directly observing its interaction in underground detectors. I will present two new efforts: DM-Ice, a sodium-iodide detector to be located in the Antarctic Ice at the South Pole, will search for the expected annual modulation of the Dark Matter signal. I will also discuss the potentialof CUORE as a Dark Matter experiment.
