We add non-linear and state-dependent terms to the Hamiltonian
of quantum field theory. The resulting low-energy theory,
non-linear quantum mechanics, is causal, preserves probability and
permits a consistent description of the process of...
I will showcase the computation of the next-to-leading order
scattering waveform in classical gravity using amplitude
techniques. I will first give an overview of how to compute generic
classical observables in gravity using scattering amplitude...
The key word in the title is “IN”. Unlike AdS where observers
can be thought of as living on the boundary of space, or even in a
laboratory beyond the boundary, in dS the observer is part of the
system; he or she lives “in” the de Sitter spacetime...
The entropy of supersymmetric black holes in string theory
compactifications can be related to that of a D- or M-brane system,
which in many cases can be further reduced to a two-dimensional
conformal field theory (CFT). For black holes in M-theory...
"Saturons" are macroscopic objects that exhibit maximal
micristate degeneracy within the validity of a given quantum
field theoretic description. Due to this feature, saturons
and black holes belong to the same universality class with common
key...
Some aspects of the black hole spectrum, coming from spacetime
wormhole contributions, can be modeled by a random matrix ensemble.
It is important to understand the appropriate ensemble for theories
with extended supersymmetry, since for example...
Perhaps the most important problem in physics or quantum
chemistry is to determine properties of the ground state of an
interacting system of fermions. As a quantum mechanical
problem, there may be no efficient classical witness to the ground
state...
The CνB is a cosmological relic analogous to the CMB, and
contains information about the universe before it was
one-second-old. Reflection of relic neutrinos from the surface of
the Earth creates a significant local neutrino-antineutrino
asymmetry...
Supersymmetric black holes in Anti de-Sitter space have recently
been shown to have a large number of exactly degenerate
microstates. In the first part of the talk, we will review how AdS5
black hole microstates may be reliably counted in the dual N...
