Correspondence between the self-dual model and the topologically massive electrodynamics: A new view
(2013-04-24)
Following the study of the Topologically Massive Theories under the Hamilton-Jacobi, we now analyze the constraint structure of the Self-Dual model as well as its correspondence with the Topologically Massive Electrodynamics. ...
Hamiltonian analysis and positivity of a new massive spin-2 model
(2022-02-03)
Recently a new model has been proposed to describe free massive spin-2 particles in D dimensions in terms of a non symmetric rank-2 tensor e μν and a mixed symmetry tensor B μ[αβ]. The model is invariant under linearized ...
Higher spin analogs of linearized topologically massive gravity and linearized new massive gravity
(2021-10-15)
We suggest a new spin-4 self-dual model (parity singlet) and a new spin-4 parity doublet in D=2+1. They are of higher order in derivatives and are described by a totally symmetric rank-4 tensor without extra auxiliary ...
Micro failure region models inducing massive correlated failures on network topologies
(2018)
Natural disasters, depending on both how many occur concurrently
and their size, may produce large-scale correlated failures in
data network infrastructure. These failures may cause service interruptions
due to disconnections ...
Topologically massive gravity at the chiral point is not unitary
(Springer, 2008-12)
A recent paper [1] claims that topologically massive gravity contains only chiral boundary excitations at a particular value of the Chern-Simons coupling. On the other hand, propagating bulk degrees of freedom with negative ...
