Scalar-multi-tensorial equivalence for higher order f (R,del R-mu,del(mu 1)del R-mu 2, ... ,del(mu 1) ... del R-mu n) theories of gravity
(Amer Physical Soc, 2016-06-13)
The equivalence between theories depending on the derivatives of R, i.e. f(R, del R, ... ,del R-n), and scalar-multi-tensorial theories is verified. The analysis is done in both metric and Palatini formalisms. It is shown ...
Scalar-multi-tensorial equivalence for higher order f (R,μR,μ1μ2R,...,μ1...μnR) theories of gravity
(2016-06-13)
The equivalence between theories depending on the derivatives of R, i.e. f(R,R,...,nR), and scalar-multi-tensorial theories is verified. The analysis is done in both metric and Palatini formalisms. It is shown that ...

Effective lagrangian for a mass dimension one fermionic field in curved spacetime
(Springer, 2018)
In this work we use momentum-space techniques to evaluate the propagator G(x
Particle creation in a f(R) theory with cosmological constraints
(Springer, 2014-04-01)
In this paper we study the creation of super-massive real scalar particles in the framework of a f (R) = R - beta/R-n modified gravity theory, with parameters constrained by observational data. The analysis is restrict to ...

Spectral and scattering theory of one-dimensional coupled photonic crystals
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2021)
We study the spectral and scattering theory of light transmission in a system consisting of two asymptotically periodic waveguides, also known as one-dimensional photonic crystals, coupled by a junction. Using analyticity ...
