The density of states of a unitary conformal field theory is
known to have a universal behavior at high energy. In two
dimensions, this behavior is described by the Cardy formula. If the
theory has symmetry, it is interesting to understand the...
It is widely believed that the physics of diffraction imposes
certain fundamental limits on the resolution of an optical system.
In this work we study the diffraction limit as a statistical
inverse problem in increasingly more realistic mathematical...
I will present a new evidence for dark matter from the
measurement of the deceleration of the Galactic bar. Galactic bars
are linear structures that form and rotate at the center of
galactic disks. In the presence of dark matter haloes, these
