Long-range entangled qubits (or quantum spins) from new states of matter whose low energy effective theory realize topological quantum field theories. Those topologically ordered states of purely bosonic qubits can produce emergent gauge theory and...

Classical conformal blocks appear in the limit c->infinity of the Virasoro conformal blocks. Classical conformal blocks have close relationship to monodromy of the second order differential equations with regular singularities. I will discuss...

The electron edm is an important constraint on extensions to the Standard Model such as supersymmetric models. ACME is closing in on a more sensitive measurement of this moment, profiting from the huge electric field within the ThO molecule.

Massless particle states carry integer or half-integer spin about themomentum axis, or "helicity". Lorentz symmetry allows for helicity states to mix under boosts (like massive particle polarizations); such mixing is not understood theoretically and...

In this talk I discuss that non-commutative and non-associative geometry emerges for closed strings moving in non-geometric backgrounds. The origin of closed string non-commutativity (non-associativity) is due to new closed string boundary...

I'll describe a new link between supersymmetric gauge theories, with gauge group G, and the Yangian for the Lie algebra of G. The main result is that a certain twisted, deformed N=1 supersymmetric gauge theory, with gauge group G, is "controlled" by...

I will discuss an old argument suggesting that thermodynamics of vacuum fluctuations implies that spacetime causal structure is dynamical and governed by Einstein's equation. Various probes of the consistency of this reasoning and implications for...

I argue that the following three widely believed statements cannot all be true: (i) Hawking radiation is in a pure state, (ii) the information carried by the radiation is emitted from the region near the horizon, with low energy effective field...
