New edge modes and corner charges for first-order symmetries of 4D gravity
Simon Langenscheidt, Daniele Oriti
We present a set of noncommuting frame-translation symmetries in 4D gravity in tetrad-connection variables, which allow expressing diffeomorphisms as composite transformations. Wor…

Channel-State duality with centers
Simon Langenscheidt, Eugenia Colafranceschi, Daniele Oriti
We study extensions of the mappings arising in usual channel-state duality to the case of Hilbert spaces with a direct sum structure. This setting arises in representations of alge…
