Half-BPS supergravity solutions and superalgebras
Eric D'Hoker, John Estes, Michael Gutperle +2
We establish a correspondence between certain Lie superalgebras with 16 fermionic generators, and half-BPS solutions to supergravities with 32 supersymmetries. Three cases are disc…
Quantum Fields on Star Graphs with Bound States at the Vertex
B. Bellazzini, M. Mintchev, P. Sorba
We investigate the propagation of a massless scalar field on a star graph, modeling the junction of quantum wires. The vertex of the graph is represented by a point-like impuri…
Quantum Field Theory on Star Graphs
B. Bellazzini, M. Burrello, M. Mintchev +1
We discuss some basic aspects of quantum fields on star graphs, focusing on boundary conditions, symmetries and scale invariance in particular. We investigate the four-fermion bulk…
