A non-perturbative analysis of spin-boson interactions using the Weyl relations
José de Ramón, Eduardo Martin-Martinez
We perform a non-perturbative analysis of the dynamics of a two-level quantum system subjected to repeated interactions with a bosonic environment when these interactions are inten…
Duality in the dynamics of Unruh-DeWitt detectors in conformally related spacetimes
Masahiro Hotta, Achim Kempf, Eduardo Martín-Martínez +2
We prove a nonperturbative duality concerning the dynamics of harmonic-oscillator-type Unruh-DeWitt detectors in curved spacetimes. Concretely, using the Takagi transformation we s…
Transmission of quantum information through quantum fields
Petar Simidzija, Aida Ahmadzadegan, Achim Kempf +1
We investigate the quantum channel consisting of two localized quantum systems that communicate through a scalar quantum field. We choose a scalar field rather than a tensor or vec…
Faster-than-light signalling in the rotating-wave approximation
Nicholas Funai, Eduardo Martin-Martinez
We present new results on the causality violations introduced by the rotating wave approximation commonly used in quantum optics and high-energy physics. We find that the causality…
Zeno Friction and Anti-friction from Quantum Collision Models
Daniel Grimmer, Achim Kempf, Robert B. Mann +1
We analyze the quantum mechanics of the friction experienced by a small system as it moves non-destructively with velocity over a surface. Specifically, we model the interactio…
Work distributions on quantum fields
Alvaro Ortega, Emma McKay, Álvaro M. Alhambra +1
We study the work cost of processes in quantum fields without the need of projective measurements, which are always ill defined in quantum field theory. Inspired by interferometry…
Fundamental limitations to local energy extraction in quantum systems
Álvaro M. Alhambra, Georgios Styliaris, Nayeli A. Rodriguez-Briones +2
We examine when it is possible to locally extract energy from a bipartite quantum system in the presence of strong coupling and entanglement, a task which is expected to be restric…
A classification of Markovian fermionic Gaussian master equations
Marvellous Onuma-Kalu, Daniel Grimmer, Robert B. Mann +1
We introduce a classification scheme for the generators of open fermionic Gaussian dynamics. We simultaneously partition the dynamics along the following four lines: (1) unitary ve…
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…

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…
