Kappa-deformed Snyder spacetime
S. Meljanac, D. Meljanac, A. Samsarov +1
We present Lie-algebraic deformations of Minkowski space with undeformed Poincare algebra. These deformations interpolate between Snyder and kappa-Minkowski space. We find realizat…
Phase diagram of epidemic spreading - unimodal vs. bimodal probability distributions
Alen Lancic, Nino Antulov-Fantulin, Mile Sikic +1
The disease spreading on complex networks is studied in SIR model. Simulations on empirical complex networks reveal two specific regimes of disease spreading: local containment and…
Constraints on the quantum gravity scale from kappa - Minkowski spacetime
A. Borowiec, Kumar S. Gupta, S. Meljanac +1
We compare two versions of deformed dispersion relations (energy vs momenta and momenta vs energy) and the corresponding time delay up to the second order accuracy in the quantum g…
The Spacetime View of the Information Paradox
H. Nikolic
In semiclassical gravity, the final state of black-hole evaporation cannot be described by a pure state. Nevertheless, we point out that the system can be described by a generalize…
Measurement of radiative capture to and for between 514 and 750 MeV/
S. Prakhov, P. Vancraeyveld, N. Phaisangittisakul +24
Differential cross sections for radiative capture in flight on the proton, leading to the and final states, have been measured at eight momenta between 514…
The Relaxed Universe: towards solving the cosmological constant problem dynamically from an effective action functional of gravity
Florian Bauer, Joan Sola, Hrvoje Stefancic
We present an unconventional approach for addressing the old cosmological constant (CC) problem in a class of F(R,G) models of modified gravity. For a CC of arbitrary size and sign…
