Particle detectors for probing of relativistic quantum theories
Particle detectors are localized and controllable quantum systems that are locally coupled in space and time to quantum fields, thus providing us with a framework for the analysis of local aspects in quantum field theory.
Initially formulated for studying phenomena such as the Unruh and Hawking effects, particle detector models have been developed for affording more general questions. Among these developments we find the introduction of switching processes, inherited from the physics of superconducting qubits and other light-matter interaction models.
To fully determine the properties of relativistic fields in curved space-times just with the interaction of particle detectors is a serious challenge, and whether or not it can be done concerns and requires the formalism of a wide variety of disciplines in theoretical physics and mathematics. Among these, we can find functional analysis and operator theory, quantum field theory, quantum and classical information, open quantum systems, quantum thermodynamics, general relativity and even quantum gravity.
In this pre-comprehensive seminar, we briefly review the background in particle detector models, we discuss our previous papers in the field, and open a window to future works.
