Hamilton Colloquium Series, Marc Kamionkowski, Johns Hopkins University, "News from Cosmic Dark Sectors"
Wed, Apr 27, 2022, 4:00 pm

Cosmologists are proud of the standard cosmological model that has been developed to account for a wealth of disparate features of the Universe. The model requires, though, that we postulate the existence of some collisionless dark matter and also dark energy, a negative-pressure substance. The nature of both of these dark constituents is a...

Thu, Nov 19, 2020, 12:15 pm

String theory landscape of vacua point to new consistency conditions that a quantum gravitational system must satisfy.  There are only a small number of quantum field theories that satisfy these conditions and all the rest belong to the `Swampland' which cannot be consistently coupled to gravity.  In this talk I review some of these conditions...

Hamilton Colloquium Series, Monika Schleier-Smith, Stanford University, "Choreographing Quantum Spin Dynamics with Light"
Thu, Nov 5, 2020, 12:00 pm

The power of quantum information lies in its capacity to be non-local, encoded in correlations among two, three, or many entangled particles.  Yet our ability to produce, understand, and exploit such correlations is hampered by the fact that the interactions between particles and ordinarily local.

Thu, Oct 29, 2020, 12:00 pm

Neutron stars are by far the strongest known magnets in the universe. Some of them (called magnetars) generate explosions by suddenly dissipating magnetic energy with a rate up to $10^{47}$ erg/s. These magnetic explosions emit giant gamma-ray flares observed in our and neighboring galaxies.

Hamilton Colloquium Series, Luis Fernando Alday, Oxford University, "Quantum Scattering Amplitudes in AdS/CFT"
Thu, Feb 20, 2020, 4:00 pm

The AdS/CFT correspondence maps correlators of local operators in a conformal field theory to scattering amplitudes in a gravitational/string theory on curved space-time. The study of such amplitudes is incredibly hard and has mostly been done in a certain classical limit. We show how modern analytic bootstrap techniques allow us to go much...
