Raleigh N.C.
Speaker: Albino Perego (Darmstadt University)
During the merger of two neutron stars, matter can be ejected in the interstellar medium through different channels. The ejection mechanism, as well as the expansion timescale, can influence deeply the matter properties and, eventually, the subsequent nucleosynthesis. In this talk, I will present... Read More »

Speaker: Jamie Bock (Caltech)
"Searching for Vibrations from the Big Bang with BICEP2" Moments after the Big Bang, our observable universe underwent a violent growth spurt called inflation. The inflationary expansion flung apart the observable universe from a causally-connected sub-atomic volume, and established a primordial... Read More »

Raleigh N.C.
Speaker: Alfred Shapere (University of Kentucky)
Time crystals are a class of systems which exhibit motion in their lowest-energy states. Their Lagrangians have unconventional kinetic terms and their Hamiltonians are multivalued functions of momentum, yet they are amenable to quantization. Field theoretic generalizations may have applications in... Read More »

Chapel Hill N.C.
Speaker: Thomas Dumitrescu (Harvard University)
Duke - UNC joint seminar at UNC, Philips 277.

Physics 298
Speaker: Eduardo Novais
The surface code is a promising alternative for implementing fault-tolerant, large-scale quantum information processing. Its high threshold for single-qubit errors under stochastic noise is one of its most attractive features. We develop an exact formulation for the fidelity of the surface code... Read More »

Physics 128
Speaker: Paul Kwiat (University of Illinois, Urbana-Champaign)
"Quantum Entanglement for Fun and Profit: 101 Uses for Schroedinger's Cat" Nearly 80 years after Schroedinger described entanglement as the quintessential nonclassical phenomenon, and 50 years after Bell showed the inconsistency of quantum correlations with local realism, the quantum information...

Physics 128
Speaker: Arthur Kosowsky (University of Pittsburgh)
We live in a universe whose properties are remarkably well described by a very early epoch of accelerating expansion, termed inflation. One generic prediction of inflation is a relic background of stochastic gravitational radiation. These tensor metric perturbations leave a distinctive imprint in... Read More »
