Quantum Shockwave Communication
Aida Ahmadzadegan, Eduardo Martin-Martinez, Achim Kempf
We present a scheme to produce shockwaves in quantum fields by means of pretimed emitters. We find that by suitably pre-entangeling the emitters, the shockwave's energy density can…
Zero mode suppression of superluminal signals in light-matter interactions
Erickson Tjoa, Eduardo Martin-Martinez
We show how two Unruh-DeWitt detectors that do not couple to the zero mode of a quantum field can exchange information faster than the speed of light. We analyze the specific cases…
Unruh-DeWitt detectors and entanglement: the anti-de Sitter space
Keith K. Ng, Robert B. Mann, Eduardo Martin-Martinez
We investigate entanglement harvesting in AdS. Applying the general results of [Phys. Rev. D 97, 125011 (2018)], we consider two scenarios: one where two particle detectors are…
Harvesting correlations from thermal and squeezed coherent states
Petar Simidzija, Eduardo Martin-Martinez
We study the harvesting of entanglement and mutual information by Unruh-DeWitt particle detectors from thermal and squeezed coherent field states. We prove (for arbitrary spatial d…
Entanglement harvesting from multiple massless scalar fields and divergences in Unruh-DeWitt detector models
Allison M. Sachs, Robert B. Mann, Eduardo Martin-Martinez
We analyze scenarios in which pairs of Unruh-DeWitt-like detectors interact with scalar field(s) with bi-linear and quadratic coupling. For all cases -- real scalar fields, charged…
Casimir forces and quantum friction of finite-size atoms in relativistic trajectories
Pablo Rodriguez-Lopez, Eduardo Martin-Martinez
We study quantum friction and Casimir forces with a full-relativistic formalism for atoms modelled as Unruh-DeWitt detectors in the presence of arbitrary macroscopic objects. We co…
vs : Gauge invariance in quantum optics
Nicholas Funai, Jorma Louko, Eduardo Martin-Martinez
We compare the predictions of the fundamentally motivated minimal coupling () and the ubiquitous dipole coupling ($\hat{\boldsymbol{x…
Particle Detectors, Cavities, and the Weak Equivalence Principle
Erickson Tjoa, Robert B. Mann, Eduardo Martin-Martinez
We analyze a quantum version of the weak equivalence principle, in which we compare the response of a static particle detector crossed by an accelerated cavity with the response of…
Direct measurement of the two-point function in quantum fields
Jose de Ramon, Luis J. Garay, Eduardo Martin-Martinez
We analyze fast interaction cycles in bipartite quantum systems, showing that the statistics in one of the parties (the detector) can be used to determine the two-point correlator…
New techniques for entanglement harvesting in flat and curved spacetimes
Keith K. Ng, Robert B. Mann, Eduardo Martin-Martinez
We present a new technique for computing entanglement harvesting with Unruh-DeWitt particle detectors. The method is particularly useful in cases where analytic solutions are rare…
Relativity and quantum optics: accelerated atoms in optical cavities
Richard Lopp, Eduardo Martin-Martinez, Don N. Page
We analyze the physics of accelerated particle detectors (such as atoms) crossing optical cavities. In particular we focus on the detector response as well as on the energy signatu…
Thermal Contact: Mischief and Time Scales
Daniel Grimmer, Robert B. Mann, Eduardo Martin-Martinez
We discuss what kind of quantum channels can enable thermalization processes. We show that in order to determine a system's temperature, a thermometer needs to dynamically gain inf…
Fluctuations of work cost in optimal generation of correlations
Emma McKay, Nayeli A. Rodriguez-Briones, Eduardo Martin-Martinez
We study the impact of work cost fluctuations on optimal protocols for the creation of correlations in quantum systems. We analyze several notions of work fluctuations to show that…
The Unruh effect without thermality
Raul Carballo-Rubio, Luis J. Garay, Eduardo Martin-Martinez +1
We show that uniformly accelerated detectors can display genuinely thermal features even if the Kubo-Martin-Schwinger (KMS) condition fails to hold. These features include satisfyi…
General no-go theorem for entanglement extraction
Petar Simidzija, Robert H. Jonsson, Eduardo Martin-Martinez
We study under what circumstances a separable bipartite system A-B can or cannot become entangled through local interactions with a bi-local entangled source -$\text{S}…
Relativistic Quantum Optics: On the relativistic invariance of the light-matter interaction models
Eduardo Martin-Martinez, Pablo Rodriguez-Lopez
In this note we discuss the invariance under general changes of reference frame of all the physical predictions of particle detector models in quantum field theory in general and,…
Gaussian ancillary bombardment
Daniel Grimmer, Eric Brown, Achim Kempf +2
We analyze in full detail the time evolution of an open Gaussian quantum system rapidly bombarded by Gaussian ancillae. As a particular case this analysis covers the thermalization…
