Homological invariants of Pauli stabilizer codes
Blazej Ruba, Bowen Yang
We study translationally invariant Pauli stabilizer codes with qudits of arbitrary, not necessarily uniform, dimensions. Using homological methods, we define a series of invariants…
Nilpotent symmetries as a mechanism for Grand Unification
Lars Andersson, Andras Laszlo, Blazej Ruba
In the classic Coleman--Mandula no-go theorem which prohibits the unification of internal and spacetime symmetries, the assumption of the existence of a positive definite invariant…
Satisfying positivity requirement in the Beyond Complex Langevin approach
Adam Wyrzykowski, Błażej Ruba
The problem of finding a positive distribution, which corresponds to a given complex density, is studied. By the requirement that the moments of the positive distribution and of th…
Characterization of Null Geodesics on Kerr Spacetimes
Claudio F. Paganini, Blazej Ruba, Marius A. Oancea
We consider null geodesics in the exterior region of a subextremal Kerr spacetime. We show that most well-known fundamental properties of null geodesics can be represented on one p…
