Measurement theory in local quantum physics

Exploring the implications of the laws and principles of quantum physics in the field of talent (quantum theory of talent)

The issue of talent-discovering is one of the most important issues in the field of education and research that has always been a concern for educational systems. Studying the issues of identifying and guiding talented students can illuminate a large part of the activities of the executors and practitioners in order to accomplish their mission effectively. On the other hand, quantum physics has...

Wigner Particle Theory and Local Quantum Physics Lucio

Wigner’s theory of positive energy representations of the Poincaré group has been often used to give additional justifications for the Lagrangian quantization approach to QFT. Here we show that by extension with a modular localization structure it can directly lead to the net of local algebras without the use of any pointlike field-coordinatization. The same modular methods reveal that among th...

Basic Quantum Theory and Measurement from the Viewpoint of Local Quantum Physics Lqp Principles and Some Consequences

Several aspects of the manifestation of the causality principle in LQP (local quantum physics) are reviewed or presented. Particular emphasis is given to those properties which are typical for LQP in the sense that they do go beyond the structure of general quantum theory and even escape the Lagrangian quantization methods of standard QFT. The most remarkable are those relating causality to the...
