Ultraviolet structure of entanglement harvesting from energy density and other quadratic couplings
Matheus H. Zambianco, Boris Ragula, Eduardo Martín-Martínez
We study entanglement harvesting with particle detectors coupled to the renormalized energy density of a massless scalar field. Our analysis identifies the distributional mechanism…

A review of applications of Quantum Energy Teleportation: from experimental tests to thermodynamics and spacetime engineering
Boris Ragula, Eduardo Martín-Martínez
Quantum energy teleportation (QET) exploits the existence of correlations to enable remote energy transfer without the need for physical energy carriers between emitter and receive…

Localizing quantum fields with time-dependent potentials
Boris Ragula, Bruno de S. L. Torres, Erik Schnetter +1
In this paper we study the effect of localizing quantum field degrees of freedom by dynamically growing cavity walls through a time-dependent potential. We use our results to show…
