Abstract: The 1+1-dimensional adjoint QCD
theory (namely SU(N) gauge theory coupled to a Majorana fermion in
the adjoint representation of the gauge group) has two curious
properties. When the fermion is massless, the theory exhibits
screening of...
Abstract: What is the mathematical question
about the S-matrix to which string amplitudes are the answer?
In this talk, I will show that both the four-point Veneziano and
Virasoro-Shaprio amplitudes, along with the string spectrum itself,
are the...
Abstract: AI progress is accelerating, and now
the leaders expect “artificial general intelligence” (AGI) in 2 to
3 years. While difficult to believe, we must prepare for the
possibility. We can take some lessons from previous episodes in
which...
Abstract: The holographic principle states that
in the limit of a large number of degrees of freedom, some quantum
systems give rise to an emergent gravitational spacetime with one
more dimension. What are these quantum systems, and which
properties...
Abstract: Despite the undeniable success of the
Large Hadron Collider (LHC), Beyond the Standard Model (BSM)
physics remains elusive. In this talk, I will outline a
multifaceted strategy to maximize discovery potential at current
and future high...
Abstract: I will start with a broad overview of
the theory of initial conditions of the universe, what we know and
what we hope to know in the near future.
Then I will describe some recent work. Motivated by precision
calculations in primordial...
Abstract: A remarkable feature of general
relativity is the presence of spacetime singularities. One of the
central aims of a complete theory of (quantum) gravity is to
resolve these singularities. In this talk, I will describe ongoing
work—building...
Abstract: Type II string theory has BPS
brane bound states that carry two charges. I will show that
their microcanonical ensemble average corresponds to a
spherical black hole mimicker, which possesses a long throat,
shares the same asymptotic data...
