Non-Baryonic Dark Matter in Cosmology
This paper is a broad-band review of the current status of non-baryonic dark
matter research. I start with a historical overview of the evidences of dark
matter existence, then I discuss how dark matter is distributed from small
scale to large scale, and I then verge the attention to dark matter nature:
dark matter candidates and their detection. I finally discuss some of the
limits of the CDM model, with particular emphasis on the small scale
problems of the paradigm.Comment: 62 pages; 58 figure
Frictionless quantum quenches in ultracold gases: a quantum dynamical microscope
In this article, a method is proposed to spatially scale up a trapped
ultracold gas while conserving the quantum correlations of the initial
many-body state. For systems supporting self-similar dynamics, this is achieved
by implementing a many-body finite-time frictionless quantum quench of the
harmonic trap which acts as a quantum dynamical microscope.Comment: 5 pages, 3 figure
