Unitarity of spin - 2 theories with linearized
Here we prove unitarity of the recently found fourth-order self-dual model of spin-2 by investigating the analytic structure of its propagator. The model describes massive particles of helicity +2 (or-2) in D = 2 + 1 and corresponds to the quadratic truncation of a higher derivative topologically massive gravity about a flat background. It is an intriguing example of a theory where a term in th...
متن کامل2 Energy spectrum of the equal spin - spin interactions Hamiltonian
The energy spectrum of eigenvalues of the equal spin-spin interactions (ESSI) Hamiltonian has been found. The obtained spectrum is free from limitations imposed on number of spins and parameters of the ESSI Hamiltonian. This model can be used for consideration of spin dynamics of mesoscopic systems and molecules with large number of nuclei spins.
متن کاملPurely Transmitting Defect Field Theories
We define an infinite class of integrable theories with a defect which are formulated as chiral defect perturbations of a conformal field theory. Such theories can be interacting in the bulk, and are purely transmitting through the defect. The examples of the sine-Gordon theory and Ising model are worked out in some detail.
متن کاملSpin Topological Quantum Field Theories
Starting from the quantum group Uq(sl(2, C)), we construct operator invariants of 3-cobordisms with spin structure, satisfying the requirements of a topological quantum field theory and refining the Reshetikhin–Turaev and Turaev–Viro models. We establish the relationship between these two refined models.
متن کاملHolography and Defect Conformal Field Theories
We develop both the gravity and field theory sides of the Karch-Randall conjecture that the near-horizon description of a certain D5-D3 brane configuration in string theory, realized as AdS5×S bisected by an AdS4×S “brane”, is dual to N = 4 Super Yang-Mills theory in R coupled to an R3 defect. We propose a complete Lagrangian for the field theory dual, a novel “defect superconformal field theor...
