Undecidability in Spacetime Geometry via the AdS/CFT Correspondence
Sameer Ahmad Mir, Francesco Marino, Arshid Shabir +2
Undecidability, a hallmark of Gödel incompleteness theorems, has recently emerged in quantum many-body physics through the spectral gap problem. We demonstrate how this logical lim…
Quantization of Yang-Mills Theory in de Sitter Spacetime
Aasiya Shaikh, Mir Faizal, Naveed Ahmad Shah
In this paper, we analyze the quantization of Yang-Mills theory in the de Sitter spacetime. It is observed that the Faddeev--Popov ghost propagator is divergent in this spacetime.…
Causality in String Field Theory
Arshid Shabir, Naveed Ahmad Shah, Salman Sajad Wani +3
In this letter, we will investigate causality in string field theory using pp-wave light-cone gauge string field theory. We will generalize the Ramsey scheme to string field theory…
Evading Weinberg's no-go theorem to construct mass dimension one fermions: Constructing darkness
Dharam Vir Ahluwalia
Recent theoretical work reporting the construction of a new quantum field of spin one half fermions with mass dimension one requires that Weinberg's no go theorem must be evaded. H…
Dynamical structure of Pure Lovelock gravity
Naresh Dadhich, Remigiusz Durka, Nelson Merino +1
We study dynamical structure of Pure Lovelock gravity in spacetime dimensions higher than four using the Hamiltonian formalism. The action consists of cosmological constant and a s…
Early-time cosmological solutions in Einstein-scalar-Gauss-Bonnet theory
Panagiota Kanti, Radouane Gannouji, Naresh Dadhich
In this work, we consider a generalised gravitational theory that contains the Einstein term, a scalar field and the quadratic Gauss-Bonnet term. We focus on the early-universe dyn…
