No black holes from light
Ãlvaro Ãlvarez-DomÃnguez, Luis J. Garay, Eduardo MartÃn-MartÃnez +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…
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…
Toward a physically motivated notion of Gaussian complexity geometry
Bruno de S. L. Torres, Eduardo MartÃn-MartÃnez
We present a general construction of a geometric notion of circuit complexity for Gaussian states (both bosonic and fermionic) in terms of Riemannian geometry. We lay out general c…
Interference of communication and field correlations in entanglement harvesting
Matheus H. Zambianco, Adam Teixidó-Bonfill, Eduardo MartÃn-MartÃnez
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…
