Hamiltonian analysis of higher derivative scalar-tensor theories
We perform a Hamiltonian analysis of a large class of scalar-tensor Lagrangians which depend quadratically on the second derivatives of a scalar field. By resorting to a convenient choice of dynamical variables, we show that the Hamiltonian can be written in a very simple form, where the Hamiltonian and the momentum constraints are easily identified. In the case of degenerate Lagrangians, which...
متن کاملScintillation in scalar-tensor theories of gravity
We study the scintillation produced by time-varying gravitational fields within scalar-tensor theories of gravity. The problem is treated in the geometrical optics approximation for a very distant light source emitting quasi plane monochromatic electromagnetic waves. We obtain a general formula giving the time dependence of the photon flux received by a freely falling observer. In the weak-fiel...
متن کاملHigher-Derivative Massive Fermion Theories
We propose and canonically quantize a generalization of the two-dimensional massive fermion theory described by a Lagrangian containing third-order derivatives. In our approach the mass term contains a derivative coupling. The quantum solution is expressed in terms of three usual fermions. Employing the standard bosonization scheme, the equivalent boson theory is derived. The results obtained a...
متن کاملScalar Tensor Theories and Hadamard State Condition
The Hadamard state condition is used to analyze the local constraints on the two-point function of a quantum field conformally coupled to a background geometry. Using these constraints we develop a scalar tensor theory which controls the coupling of the stresstensor induced by the two-point function of the quantum field to the conformal class of the background metric. It is then argued that the...
متن کاملscalar-tensor theories for traceless matter field
ω(φ) → ∞ limit of scalar tensor theories are studied for traceless matter source. It is shown that the limit ω(φ) → ∞ does not reduce a scalar tensor theory to GR. An exact radiation solution of scalar tensor cosmology under modified Nordtvedt conditions is obtained for flat Friedmann universe. PACS numbers: 04.50. +h
