Dimensional reduction of cavities with axial symmetry: A complete analysis of when an optical fiber is approximately one-dimensional
Daniel Grimmer, Richard Lopp, Eduardo Martín-Martínez
Intuition dictates that a very long, very thin cavity (e.g., a fiber optic cable) could perhaps be modeled as an approximately one dimensional system. In this paper we rigorously e…
What makes a particle detector click
Erickson Tjoa, Irene López Gutiérrez, Allison Sachs +1
We highlight fundamental differences in the models of light-matter interaction between the behaviour of Fock state detection in free space versus optical cavities. To do so, we stu…
Relativistic causality in particle detector models: Faster-than-light signalling and "Impossible measurements"
José de Ramón, Maria Papageorgiou, Eduardo Martín-Martínez
We analyze potential violations of causality in Unruh DeWitt-type detector models in relativistic quantum information. We proceed by first studying the relation between faster-than…
The Unruh effect in slow motion
Silas Vriend, Daniel Grimmer, Eduardo Martín-Martínez
We show under what conditions an accelerated detector (e.g., an atom/ion/molecule) thermalizes while interacting with the vacuum state of a quantum field in a setup where the detec…
Quantum delocalization, gauge and quantum optics: The light-matter interaction in relativistic quantum information
Richard Lopp, Eduardo Martín-Martínez
We revisit the interaction of a first-quantized atomic system (consisting of two charged quantum particles) with the quantum electromagnetic field, pointing out the subtleties rela…
The First Law of Quantum Field Thermodynamics
Adam Teixidó-Bonfill, Alvaro Ortega, Eduardo Martín-Martínez
We study the notion of work fluctuations in quantum field theory, highlighting that the most common definitions used in finite-dimensional quantum systems cannot be applied to quan…
