A bound on galactic mass loss rates obtaind from globular cluster dynamics
Florian Dubath, Anna Rissone
Using tidal disruption of globular clusters by the galactic center, we put limits on the total mass ever enclosed into orbits of observed globular clusters. Under the assumption th…
Electronic contribution to the oscillations of a gravitational antenna
Vincenzo Branchina, Alice Gasparini, Anna Rissone
We carefully analyse the contribution to the oscillations of a metallic gravitational antenna due to the interaction between the electrons of the bar and the incoming gravitational…
String hamiltonian from generalized YM gauge theory in two dimensions
Florian Dubath, Simone Lelli, Anna Rissone
Two dimensional SU(N) Yang-Mills theory is known to be equivalent to a string theory, as found by Gross in the large N limit, using the 1/N expansion. Later it was found that even…
Perturbative and non-perturbative aspects of the two-dimensional string/Yang-Mills correspondence
Simone Lelli, Michele Maggiore, Anna Rissone
It is known that YM_2 with gauge group SU(N) is equivalent to a string theory with coupling g_s=1/N, order by order in the 1/N expansion. We show how this results can be obtained f…
