Neutrino Oscillations in the Model of Interaction of Spinor Fields with Zero-Range Potential Concentrated on a Plane

Symanzik’s approach to the description of quantum field systems in an inhomogeneous space-time is used to construct a model for the interaction of neutrino fields with matter. In this way, the problem of the influence of strong inhomogeneities of the medium on the processes of oscillations is considered. As a simple example, a model of neutrino scattering on a material plane is investigated. Within this model, in the collisions of particles with planes, a special filtration mechanism can be formed. It has a significant impact on the dynamics of subsequent neutrino oscillations which are analogous to the Mikheev-Smirnov-Wolfenstein effect at propagation of these particles in an adiabatic medium. Taking into account the possibility of the filtration process in a highly inhomogeneous environment can be useful in planning and carrying out experimental studies of neutrino physics. It can also be considered by investigations of the role of neutrino in astrophysical processes by means of numerical simulations methods.

Primed Prediction: A Critical Examination of the Consequences of Exclusion of the Ontological Now in AI Protocol

Revisiting Norbert Wiener’s cybernetic prediction as the theoretical foundation of AI this chapter makes a plea how we need to uncover the black box of what is behind prediction and simulation. It explores the shortcomings of cybernetic prediction, the theoretical foundation of Artificial Intelligence, through the lens of Jean Baudrillard’s simulacra and simulation. Specifically, what prediction excludes – namely, an accounting for the ontological now – is what Baudrillard warned against in his analysis of the role technological innovations play in untethering reality from the material plane, leading to a crisis of simulacrum of experience. From this perspective, any deep-learning system rooted in the Wiener’s view of cybernetic feedback loops risks creating behaviour more so than predicting it. As this chapter will argue, such prediction is a narrow, self-referential system of feedback that ultimately becomes a self-fulfilling prophecy girded by the psycho-social effects of the very chaos it seeks to rationalise.

Bound state in a model of electromagnetic field interacting with a material plan

In the model with Chern-Simons potential describing the coupling of electromagnetic field with a two-dimensional material, the possibility of the appearance of bound field states, vanishing at sufficiently large distances from interacting with its macro-objects, is considered. As an example of such two-dimensional material object we consider a homogeneous isotropic plane. Its interaction with electromagnetic field is described by a modified Maxwell equation with singular potential. The analysis of their solution shows that the bound state of field cannot arise without external charges and currents. In the model with currents and charges the Chern-Simons potential in the modified Maxwell equations creates bound state in the form of the electromagnetic wave propagating along the material plane with exponentially decreasing amplitude in the orthogonal to its direction.

Tintoretto: Cosmic Artisan

The works of the sixteenth-century Venetian painter Jacopo Tintoretto (1518–94) present us with a radicalised idea of the cosmos that challenges both the humanist centring of the world on man and the hierarchy of divine authority that dominate the artistic traditions to which he is heir. In their place, Tintoretto confronts us with a ‘machinic’ staging of forces in which man, nature, religious figure and artificial element are integrated within an extended material plane. With this pictorial immanence, Tintoretto presents a ‘cosmic materialism’ unprecedented in Venetian painting. In this, his work gives provocative expression to Deleuze and Guattari's ontology of the artwork as ‘cosmic’ construction, and to their conception of the artist as ‘cosmic artisan’. Via readings of the art historical reception of Tintoretto's work by the art historian Arnold Hauser (1892–1978), and the artistic reception of Tintoretto's work by Paul Cézanne, I explore this expression, and attend to questions of modernity, temporality and art history as they are inflected in Deleuze and Guattari's thought.

Zero-range potential in the model of the spinor field interacting with a material plane: conditions for transparency of the plane to Dirac particles

In the model of interaction of a spinor field with a homogeneous isotropic material plane, the possibility of the passage of a Dirac particle through it without reflection and a change in polarization isstudied. The model was proposed earlier in the framework of the Symanzik approach to describe the interaction of spinor quantum fields with two-dimensional materials. In its framework the scattering processes of Dirac particles and the properties of their bound states were investigated. In this paper, we study the conditions under which the plane is completely transparent to the particles. A description of the region of model parameters characterizing the properties of the plane material is obtained explicitlyand given in the article, as well as expressions in terms of these parameters for the momentum and polarization of the particle at which interaction with the plane does not affect its movement.

Dispersion relations and dynamic characteristics of bound states in the model of a Dirac field interacting with a material plane

Symanzik’s approach for construction of quantum field model in inhomogeneous space-time is used as a basis for modeling the interaction of a macroscopic material body with quantum fields. In quantum electrodynamics it enables one to establish the most general form of the action functional describing the interaction of 2-dimensional material objects with photon and fermion fields. Results obtained within this approach for description of the interaction of the spinor field with a material plane are presented.

Sexuality and its Deviations in the Post-Modern World

As the modern world oscillates between powerful contrasts and profound discords, while promoting an individualistic relativism and placing excessive value on the biological life, seen as the only means towards fulfillment for a human existence reduced almost exclusively to the material plane, as the modern secularist views dispute Christian spiritual values more and more, the Church is called to adopt a new type of ministry. The Creed of the post modern society is the “transvaluation of all values”, which questioning and criticizing everything that offers stability to a society by anchoring it to history and tradition. Therefore, pornography, homosexuality, abortion, licentiousness and divorce have become everyday realities promoted through media and elevated to the level of a mandatory normality. Sex is now not only a commodity, but also a means to controlling the person. To overcome this real social crisis of the modern secularized society, the Christians of the 21st century are called to rediscover their liturgical vocation and the true meaning and power of the Worship with all its eschatological, ecclesiological, ascetical and cosmic dimensions and content.
