Quasinormal modes and continuum response of de Sitter black holes via complex scaling method
Even at the cost of compromising the elegance of the Kugo–Ojima framework, if one abandons global aspects of BRST cohomology and instead insists on a direct integral decomposition for observable algebra, how should the physical Hilbert space of non-pert. gauge theory be defined?
In Hamiltonian lattice gauge theory and quantum simulation, closely related issues seem to appear operationally as nonlocal encodings when Gauss law is solved and one works directly in the gauge-invariant Hilbert space.
I’d like to understand this phenomenon from AQFT.
