In the paper are described some steps for merger between relativistic quantum theory and theory of computation. The first step is consideration of transformation of qubit state due to rotation of coordinate system. The Lorentz transformation is considered after that. The some new properties of this transformation change usual model of qubit. The system of qbit seems more fundamental relativisti...

ii Preface Lately, after ∼ 50 years, there seems to be a convergence in the languages used to describe Quantum Field Theory and String Theory, such that it seems possible to relate objects from these two perspectives. Therefore, a deeper investigation of the properties and features of QFT is a reasonable thing to do: non-perturbative effects, dualities, emergent properties, non-commutative stru...

Line Current Commutated (LCC) HVDC systems consists of uncertain plants. These uncertainties are result of changes/disturbances in the ac networks or in the LCC HVDC system itself. Further uncertainties can be introduced due to simplified system modelling techniques. Quantitative Feedback Theory is a frequency-domain technique that utilises the Nichols chart to achieve a robust design over a sp...

This is a pedagogical attempt to elucidate the conceptual and mathematical differences between Lagrangian quantization, causal perturbation theory guided by the setting of algebraic QFT and some recent developments of nonperturbative intrinsic constructions of QFT based on the conceptual setting of AQFT.

We discuss a general model for effective quantum field theories (QFTs), which for example comprises quantum chromodynamics and quantum electrodynamics. We assume in the model a perturbative expansion of the Lagrangian with respect to a cut-off-energy parameter. For each order in the expansion we rigorously derive a representation, which is unitarily equivalent to the representation of the effec...

Quantum Field Theory (QFT) in Curved Spacetime is a hybrid approximate theory in which quantum matter fields are assumed to propagate in a fixed classical background gravitational field. Its basic physical prediction is that strong gravitational fields can polarize the vacuum and, when timedependent, lead to pair creation just as a strong and/or time-dependent electromagnetic field can polarize...

There are several instances where non-analytic functions and non-integrable operators are deliberately excluded from perturbative Quantum Field Theory (QFT) and Renormalization Group (RG) to maintain internal consistency of both frameworks. Here we briefly review these instances and suggest that they may be a portal to an improved understanding of the asymptotic sectors of QFT and the Standard ...

Strong periodic stimuli such as bright flashing lights evoke nonlinear responses in the brain and interact nonlinearly with ongoing cortical activity, but the underlying mechanisms for these phenomena are poorly understood at present. The dominant features of these experimentally observed dynamics are reproduced by the dynamics of a quantitative neural field model subject to periodic drive. Mod...
