Dynamics of silo deformation under granular discharge
Claudia Colonnello, Miroslav Kramar
We use Topological Data Analysis to study the post buckling behavior of laboratory scale cylindrical silos under gravity driven granular discharges. Thin walled silos buckle during…
Characterization of invariant patterns in a slowly rotated granular tumbler
Leonardo Reyes, Oscar Pérez, Claudia Colonnello +4
We report experimental results of the pattern developed by a mixture of two types of grains in a triangular rotating tumbler operating in the avalanche regime. At the centroid of t…
Silo collapse under granular discharge
G. Gutiérrez, C. Colonnello, P. Boltenhagen +4
We investigate, at a laboratory scale, the collapse of cylindrical shells of radius and thickness induced by a granular discharge. We measure the critical filling height fo…
5D supersymmetric domain wall solution with active hyperscalars and mixed AdS/non-AdS asymptotics
Jorge Bellorín, Claudia Colonnello
We find a new supersymmetric 5D solution of N = 2 supergravity coupled to one hypermultiplet that depends only on the fifth dimension (the energy scale in a holographic context). I…
Ehlers symmetry at the next derivative order
Claudia Colonnello, Axel Kleinschmidt
We analyse four-dimensional gravity in the presence of general curvature squared corrections and show that Ehlers' SL(2,R) symmetry, which appears in the reduction of standard grav…
