Noisy dynamics of confined quantum walks on a chip
L. Sansoni, E. Stefanutti, C. Benedetti +8
Quantum walks represent an excellent testbed for investigating the interplay between unitary coherent and incoherent dissipative processes. Thanks to photonic quantum interferomete…
Complexity hierarchies in Euclidean stars
L. Herrera, A. Di Prisco, J. Ospino
We establish a hierarchy of Euclidean stars according to their degree of complexity, as measured by the complexity factor and the complexity of the pattern of evolution. We conside…
The hyperbolically symmetric black hole
L. Herrera, L. Witten
We describe some properties of the hyperbolically symmetric black hole (hereafter referred to as the ) proposed a few years ago. We start by explaining the main motivation be…
Axially symmetric ghost stars
L. Herrera, J. L. Hernandez-Pastora, J. Ospino +1
We present static axially symmetric fluid distributions not producing gravitational field outside their boundaries (i.e. fluid sources which match smoothly on the boundary surface…
The birth of a ghost star
L. Herrera, A. Di Prisco, J. Ospino
We present a model of an evolving spherically symmetric dissipative self-gravitating fluid distribution which tends asymptotically to a ghost star, meaning that the end state of su…
Modified Landauer principle according to Tsallis entropy
L. Herrera
The Landauer principle establishes a lower bound in the amount of energy that should be dissipated in the erasure of one bit of information. The specific value of this dissipated e…
Evolution of self-gravitating fluid spheres involving ghost stars
L. Herrera, A. Di Prisco, J. Ospino
Exact solutions are presented which describe, either the evolution of fluid distributions corresponding to a ghost star (vanishing total mass), or describing the evolution of fluid…
Ghost stars in general relativity
L. Herrera, A. Di Prisco, J. Ospino
We explore an idea put forward many years ago by Zeldovich and Novikov concerning the existence of compact objects endowed with arbitrarily small mass. The energy-density of such o…
