Quantum Field Theory of an Accelerated Observer in Moyal Spacetime May 16, 2011

Show notes

Sachindeo Vaidya argues that an accelerating frame may be defined (i.e. as a sequence of instantaneous Lorentz transformations) in noncommutative Moyal spacetime.

Duality and Holography May 16, 2011

Show notes

Joe Polchinski discusses the idea that physics must be holographic and that the fundamental variables are nonlocal and locality is emergent; this is a complete change from previous experience, and we have much to understand.

Discrete Volume of Space via Bohr-Sommerfeld Quantization May 09, 2011

Show notes

Hal Haggard presents on computing the Bohr-Sommerfeld volume spectrum of a tetrahedron and showing that it reproduces the quantization of a grain of space found in loop gravity.

Physical Predictions and the Quantum Multiverse May 03, 2011

Show notes

Yasunori Nomura presents a framework in which well-defined predictions are obtained in an eternally inflating multiverse, based on the principles of quantum mechanics.

The EFT of Inflation: New Shapes of Non Gaussianity and Consistency Relation May 02, 2011

Show notes

Guido D'Amico presents the consequences of imposing an approximate Galilean symmetry on the Effective Theory of Inflation, the theory of small perturbations around the inflationary background.

Lower Limits on the Strengths of Gamma Ray Lines from Dark Matter Annihilation Apr 25, 2011

Show notes

Zacharia Chacko discusses the spectrum of gamma ray signals that arise from dark matter annihilation in the universe.

Identifying Physics Beyond the Standard Model at the LHC Apr 18, 2011

Show notes

Vikram Rentala proposes a new model-independent method for spin measurements which takes advantage of quantum interference among helicity states.

Deformations, Bions, and (De)confinement Apr 11, 2011

Show notes

Erich Poppitz discusses the Eguchi-Kawai reduction in the strong-coupling domain of gauge theories via the gravity dual of N=4 super-Yang-Mills on R^3xS^1.

Recast and Like-Sign Di-Leptons Apr 09, 2011

Show notes

Gaurab Sarangi gives a talk at the SUSY-Recast workshop.

Recasting SUSY Apr 09, 2011

Show notes

Jay Wacker gives a talk at the SUSY-Recast workshop.
