Phase space renormalization and finite BMS charges in six dimensions

open access: yesJournal of High Energy Physics, 2023
We perform a complete and systematic analysis of the solution space of six-dimensional Einstein gravity. We show that a particular subclass of solutions — those that are analytic near I $$ \mathcal{I} $$ + — admit a non-trivial action of the generalised ...

Modeling of sudden six-phase and three-phase short circuits of a six-phase turbogenerator

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract A demand for the highest possible power density in electrical machinery in some applications often requires a change in conventional and well-known three-phase stator winding solution. This paper discusses high-power turbogenerators with a six-phase winding. Mutual inductance between two three-phase windings requires updating of
