Motivated by the instances of Grothendieck’s generalized Hodge
conjecture which have a purely algebraic expression, we study the
restriction map in cohomology from a smooth projective variety
X
to an affine U. Starting from X being defined over an...
Trapped ion crystals are a powerful platform for quantum
simulation of
spin and spin–boson models. In this talk, I will present our
recent
experimental realization of the Dicke model in a two-dimensional
crystal
of about 100 trapped ions. Despite its...
