Quantum mechanics is distinguished by three essential features:
the Hugeness of Hilbert Space, I.e., the capacity for exponential
complexity; the phenomenon of Entanglement; and the duality between
Wave Function Collapse and Everett's Relative...
In this discussion I will present the background to the
integration-by-parts (IBP) machinery as used for Feynman integrals,
and its applications. I will also discuss recent work linking IBP
to some aspects of the algebraic geometry underlying...
I will define the hemisphere partition function for B-brane
boundary conditions in GLSMs and describe some applications to
B-brane transport on spacial classes of (non-) abelian GLSMs.
This discussion will focus on the question of how locality on
distance scales smaller than the AdS radius can emerge from a CFT.
We will introduce Landau singularities as a sign of locality in
QFT, and discuss the extent to which they are present...
I'll start reviewing some aspects of my paper with K. Hori [1]
about localization of Gauged Linear Sigma Models (GLSM) on a
disc/hemisphere. The focus is on a special class of boundary
conditions corresponding to B-branes. I'll then review the...
I will review recent progress in the computation of multiloop
scattering amplitudes using the pure spinor formalism of the
superstring and make comments about future directions.
I would like to discuss the idea that CFT entanglement explains
gravity in AdS/CFT. van Raamsdonk et al. [1] showed that the
linearized Einstein equations about the AdS vacuum are equivalent
to the entanglement first law in CFT’s, assuming the Ryu...
With an upgraded energy and calibrated detectors, the next few
years are pivotal for new physics searches at the Large Hadron
Collider (LHC). Developments over the past year have demonstrated
the power of the LHC to compliment and, in some cases...
Live stream of the LIGO press conference. Stream begins at 10:30
am. (Lecture Hall will open at 10:00 am for early arrival). 100
years after Einstein predicted the existence of gravitational
waves, the National Science Foundation gathers scientists...
