Duke Teaching Observatory
Speaker: Yuriy Bomze
Observe the solar system objects, binary stars, star clusters, galaxies and nebulas through the university's five Meade LX200 GPS Schmidt-Cassegrain telescopes. See website for directions.

Physics 298
Speaker: Christopher Wilson (University of Waterloo)
We have studied the strong coupling of a single artificial atom, formed from a superconducting qubit, to an open transmission line. This produces an almost ideal 1D quantum electrodynamic system. In a series of experiments, we have already demonstrated a number of interesting physical effects. For... Read More »

Physics 128
Speaker: Daniel Lathrop (University of Maryland)
"Liquid Sodium Models of the Earth's Core" -- During the current solar maximum, we have seen a host of x-class flares and coronal mass ejections from the sun. The fact that we saw little danger from them on Earth is due to our planetary magnetic field, which shields us from the Sun's charged... Read More »

French Family Science Center 2231
Speaker: Christopher Monroe (University of Maryland)
"Scalable Quantum Networks of Trapped Atomic Ions" Laser-cooled and trapped atomic ions are standards for quantum information science, acting as qubits with unsurpassed levels of quantum coherence while also allowing near-perfect measurement. When qubit state-dependent laser forces are applied to a... Read More »

Physics 298
Speaker: François Amet (Appalachian State University)
Combining superconductivity and the quantum Hall (QH) effect is a promising route for creating new types of topological excitations. Despite this potential, signatures of superconductivity in the quantum Hall regime remain scarce, and a superconducting current through a quantum Hall weak link has... Read More »

Physics 128
Speaker: John Wettlaufer (Yale University)
"Is Statistical Physics Relevant to Climate Science?" The science of climate emerged out of a spate of basic physics questions, ranging from the "dark heat of Joseph Fourier to John Tyndall's measurements of the infrared absorption of gases. Today, no one can deny that the Earth's climate system is... Read More »

Duke Teaching Observatory
Speaker: Yuriy Bomze
Cancelled due to poor weather conditionsObserve the solar system objects, binary stars, star clusters, galaxies and nebulas through the university's five Meade LX200 GPS Schmidt-Cassegrain telescopes. See website for directions.
Wednesday, September 23, 2015 - 3:30pm
Physics 128
Speaker: Stewart Prager (Princeton Plasma Physics Lab)
"The Path to Magnetic Fusion Energy" When the possibility of fusion as an energy source for electricity generation was realized in the 1950s, understanding of the plasma state was primitive. The fusion goal has been paced by, and has stimulated, the development of plasma physics. Our understanding... Read More »

Bostock Library - The Edge Workshop Room
Neutron scattering, neutron diffraction, and neutron imaging provide information that is highly complementary to that from other microscopic scattering techniques, and more recent technical developments have fueled the expansion of the field, originally focused on condensed matter physics, into...

Raleigh N.C.
Speaker: Ping Wang (IHEP Beijing)
I will present some applications of effective field theory in hadron structure and spectrum. Finite range regularization will be discussed in the extrapolation of lattice data on magnetic form factors, strange form factors, charge radii, first moments, etc. The unitary chiral perturbation theory is...
