Abstract: I will introduce an effective
field theory which describes scattering in the Regge limit in a
systematic triple expansion in terms of t/s, Gt, and G^2st. Using
the usual properties of the S-matrix, along with the emergent
symmetries of the...
Abstract: The structure of dark halos carries
signatures of their mass, dynamical state, and the nature of dark
matter itself. Some of the most constraining signals can be found
in the outskirts of galaxy clusters, which have recently
become...
Abstract: String spectra comprise infinitely
many physical states of arbitrarily high mass and spin, the
presence of all of which is crucial to the good UV behaviour of
string scattering amplitudes. Yet what do all these states look
like? In this...
Abstract: In this talk, I will introduce a new
approach for studying $d+1$ dimensional Euclidean Schwarzschild
black holes with Hawking temperature near the Hagedorn temperature,
as well as the Horowitz-Polchinski (HP) solutions. The
worldsheet...
Abstract: Fractionalization of the electron
charge is one of the most striking phenomena arising from strong
electron-electron interactions. A celebrated example is the
emergence of anyons with fractionally charged excitations in
fractional quantum...
Abstract: Schrodinger CFTs describe
non-relativistic fixed points with dynamical critical exponent z=2;
including the BCS-BEC crossover, heavy atoms in a harmonic trap,
nuclear physics EFTs, stochastic/Langevin systems, and
null-reductions of...
Abstract: The $\epsilon$-expansion is a widely
used technique to study aspects of renormalization group flows and
critical phenomena. In this talk, I will discuss recent
developments of the $\epsilon$-expansion in the study of boundary
and defect...
Abstract: I will argue on the possibility
that compact extra dimensions obtain large size by higher
dimensional inflation, relating the weakness of the actual
gravitational force to the size of the observable universe.
Although this can be realised...
Abstract: Recently, a qualitatively new
class of rigorous bounds on CFT data was shown to be numerically
computable from the crossing equations of six-point functions.
However, this six-point bootstrap requires solving non-standard
optimization...
