What does it mean for half of an empty cavity to be full?
Eric G. Brown, Marco del Rey, Hans Westman +2
It is well known that the vacuum state of a quantum field is spatially entangled. This is true both in free and confined spaces, for example in an optical cavity. The obvious conse…
Emergence of coherence and the dynamics of quantum phase transitions
S. Braun, M. Friesdorf, S. S. Hodgman +7
The dynamics of quantum phase transitions poses one of the most challenging problems in modern many-body physics. Here, we study a prototypical example in a clean and well-controll…
Local quanta, unitary inequivalence, and vacuum entanglement
Matias Rodriguez-Vazquez, Marco del Rey, Hans Westman +1
In this work we develop a formalism for describing localised quanta for a real-valued Klein-Gordon field in a one-dimensional box . We quantise the field using non-stationa…
Non-monotonic entanglement of physical EM field states in non-inertial frames
Miguel Montero, Marco del Rey, Eduardo Martin-Martinez
We develop a general technique to analyse the quantum effects of acceleration on realistic spatially-localised electromagnetic field states entangled in the polarization degree of…
Extracting past-future vacuum correlations using circuit QED
Carlos Sabin, Borja Peropadre, Marco del Rey +1
We propose a realistic circuit QED experiment to test the extraction of past-future vacuum entanglement to a pair of superconducting qubits. The qubit P interacts with the quantum…
Simulating accelerated atoms coupled to a quantum field
M. del Rey, D. Porras, E. Martin-Martinez
We show an analogy between static quantum emitters coupled to a single mode of a quantum field and accelerated Unruh-DeWitt detectors. We envision a way to simulate a variety of re…
