No black holes from light
Álvaro Álvarez-Domínguez, Luis J. Garay, Eduardo Martín-Martínez +1
We show that it is not possible to concentrate enough light to precipitate the formation of an event horizon. We argue that the dissipative quantum effects coming from the self-int…
Interference of communication and field correlations in entanglement harvesting
Matheus H. Zambianco, Adam Teixidó-Bonfill, Eduardo Martín-Martínez
We reveal that the information exchange between particle detectors and their ability to harvest correlations from a quantum field can interfere constructively and destructively. Th…
Thermodynamic Analysis of Algorithmic Cooling Protocols: Efficiency Metrics and Improved Designs
Junan Lin, Nayeli A. Rodríguez-Briones, Eduardo Martín-Martínez +1
Algorithmic cooling (AC) protocols have been predominantly studied for their cooling capabilities, with limited attention paid to their thermodynamic properties. This work explores…
Particle detectors under chronological hazard
Ana Alonso-Serrano, Erickson Tjoa, Luis J. Garay +1
We analyze how the presence of closed timelike curves (CTCs) characterizing a time machine can be discerned by placing a local particle detector in a region of spacetime which is c…
A proposal to characterize and quantify superoscillations
Yu Li, José Polo-Gómez, Eduardo Martín-Martínez
We present a formal definition of superoscillating function. We discuss the limitations of previously proposed definitions and illustrate that they do not cover the full gamut of s…
Non-perturbative method for particle detectors with continuous interactions
José Polo-Gómez, Eduardo Martín-Martínez
We show that detector switching profiles consisting of trains of delta couplings are a useful computational tool to efficiently approximate results involving continuous switching f…
