With the discovery of many new satellite galaxies, in recent years our understanding of the Milky Way environment has undergone a dramatic transformation. I will discuss what these discoveries are telling us about galaxy formation and the nature of dark matter itself. Issues I will focus on include: identifying the least luminous dark matter halo in the Universe, distinguishing between warm and cold dark matter, and indirect dark matter detection.

In the first part of the talk we introduce a technique to compute large scale correlations in LQG and spinfoam models. Using this formalism we calculate some components of the graviton propagator and of the n-points function.

One of the most significant questions in quantum information is about the origin of the computational power of the quantum computer; namely, from which feature of quantum mechanics and how does the quantum computer obtain its superior computational potential compared with the classical computer?

Quantum fields in the Minkowski vacuum are entangled with respect to local field modes. This entanglement can be swapped to spatially separated quantum systems using standard local couplings. A single, inertial field detector in the exponentially expanding (de Sitter) vacuum responds as if it were bathed in thermal radiation in a Minkowski universe.

We demonstrate a number of effective field theory constructions developed to
capture the effects of new physics on the Higgs sector of the standard
model. We demonstrate that as the self couplings of the Higgs
could be significantly effected by new physics, novel phenomenology such as
a two Higgs bound state (Higgsium) may be possible.
We also demonstrate that the effects of new physics
on the Higgs fermion couplings, and thus the Higgs width, could be significant.
We show that it is possible this could happen while the new physics

Cosmic strings are non-trivial configurations of scalar (and vector) fields that are stable on account of a topological conservation law.
They can be formed in the early universe as it cools after the Big Bang.
