The clustered nature of star formation leaves a long-term
imprint on galaxies, stars, and planets. At young ages, stellar
clustering subdivides galaxies into individual building blocks
undergoing vigorous, feedback-driven life cycles that vary
with...
I will discuss ongoing work about a string theoretic
perspective on the 2d Bethe/Gauge correspondence of
Nekrasov-Shatashvili. In this work, we focus on gl(M|N) spin
chains. We show that the two sides of the correspondence, the
integrable spin chain...
We present spherically symmetric solutions to Einstein’s
equations, which are equivalent to canonical Schwarzschild and
Reissner-Nordstrom black holes on the exterior, but with singular
(Planck-density) shells at their respective event and inner...
Star formation takes place in the densest and coldest parts of
the interstellar medium (ISM), in dark molecular clouds. These are
swept up by multiple supernova explosions on scales of several
hundred parsec. While condensing out of the warm ISM...
I will revisit the
quantum field theory of the Coulomb gas formalism, clarifying
several important points along the way. The first key ingredient
involves a peculiarity of the timelike linear dilaton: although the
background charge Q breaks the...
I discuss graviton non-Gaussianities in models of inflation
where de Sitter isometries are spontaneously broken. First, I
review the different symmetry breaking patterns following Nicolis,
Penco, Piazza, Rattazzi (2015), and discuss which of them...
With gate error rates in multiple technologies now below the
threshold required for fault-tolerant quantum computation, the
major remaining obstacle to useful quantum computation is scaling,
a challenge greatly amplified by the huge overhead imposed...
The Milky Way is a unique testbed for theories of galaxy
formation and evolution. Especially the stellar halo is amenable to
studies into our galaxy’s past both because it contains some of the
oldest stars and because the dynamical timescales are...
Binary neutron star mergers provide a unique probe of the
neutron star equation of state (EOS) across a wide range of
parameter space, from the zero-temperature EOS during the inspiral
to the finite-temperature EOS following the merger. In this
talk...
A symmetry is usually described by transformations and an
associated group. However, a symmetry can also be described by
the conservation of charges, encoded by their fusion rule. This
leads to a description of symmetry based on fusion category...
