Gravitational decoherence (GD) refers to the effects of gravity in actuating classical appearance a quantum system. Because underlying processes involve issues general relativity (GR), field theory (QFT), and information, GD has fundamental theoretical significance. There is great variety models, many them involving physics that diverge from GR and/or QFT. This overview two specific goals along...

The quantum field theory (QFT) is one of branches the Standard Model. According to QFT, fields are primary entities and particles excitations these fields, coming in discrete lumps with no inner structures properties assigned by declaration. Such view conflict observed vacuum energy density, 140 orders magnitudes less than required QFT. In addition, such challenged Aphysical Quantum Mechanics (...

Axiomatic QFT attempts to provide a rigorous mathematical foundation for QFT, and it is the basis for proving some important general results, such as the well-known spin-statistics theorem. Free-field QFT meets the axioms of axiomatic QFT, showing they are consistent. Nevertheless, even after more than 50 years, there is still no known non-trivial theory of quantum fields with interactions in f...

We introduce the concept of a quantum background and a functor QFT. In the case that the QFT moduli space is smooth formal, we construct a flat quantum superconnection on a bundle over QFT which defines algebraic structures relevant to correlation functions in quantum field theory. We go further and identify chain level generalizations of correlation functions which should be present in all qua...

In quantum field theory (QFT), the vacuum expectation value of a normal product of creation and annihilation operators is always zero. This simple property paves the way to the classical treatment of perturbative QFT. This is no longer the case in the presence of initial correlations, that is if the vacuum is replaced by a general state. As a consequence, the combinatorics of correlated systems...

Quaternion-valued signals along with quaternion Fourier transforms (QFT) provide an effective framework for vector-valued signal and image processing. However, the sampling theory of quaternion valued signals has not been well developed. In this paper, we present the generalized sampling expansions associated with QFT by using the generalized translation and convolution. We show that a σ-bandli...

The quantum string emission by Black Holes is computed in the framework of the ‘string analogue model’ (or thermodynamical approach), which is well suited to combine quantum field theory (QFT) and string theory in curved backgrounds (particulary here, as black holes and strings posses intrinsic thermal features and temperatures). String theory properly describes black-hole evaporation. The blac...

In this paper the problem of input-output decoupling in nonlinear singular systems is solved via the application of a particular nonlinear PD feedback control law. An invertible transformation is provided, which converts the closed loop singular system into an equivalent regular, to which a static state feedback law is applied. This transformation, hence, allows the theory that exists for the c...

this paper presents a theoretical approach to implementation of the “multi-realization of nonlinear mimo systems”. this method aims to find state-variable realization for a set of systems, sharing as many parameters as possible. in this paper a special nonlinear multi-realization problem, namely the multi-realization of feedback linearizable nonlinear systems is considered and an algorithm for ...
