Soft photon radiation and entanglement
Anastasios Irakleous, Theodore N Tomaras, Nicolaos Toumbas
We study the entanglement between soft and hard particles produced in generic scattering processes in QED. The reduced density matrix for the hard particles, obtained via tracing o…
Turnaround density as a probe of the cosmological constant
Vasiliki Pavlidou, Giorgos Korkidis, Theodore Tomaras +1
Spherical collapse predicts that a single value of the turnaround density (average matter density within the scale on which a structure detaches from the Hubble flow) characterizes…
Turnaround radius of galaxy clusters in N-body simulations
Giorgos Korkidis, Vasiliki Pavlidou, Konstantinos Tassis +3
We use N-body simulations to examine whether a characteristic turnaround radius, as predicted from the spherical collapse model in a Universe, can be meaningfully iden…
The maximum turnaround radius for axisymmetric cosmic structures
Sourav Bhattacharya, Theodore N Tomaras
Three simple idealised models are studied in order to develop some intuition about the leading order effect of non-sphericity on the maximum turnaround size of lar…
IR dynamics and entanglement entropy
Theodore N Tomaras, Nicolaos Toumbas
We consider scattering of Faddeev-Kulish electrons in QED and study the entanglement between the hard and soft particles in the final state at the perturbative level. The soft phot…
Comments on the entropic gravity proposal
Sourav Bhattacharya, Panagiotis Charalambous, Theodore N Tomaras +1
Explicit tests are presented of the conjectured entropic origin of the gravitational force. The gravitational force on a test particle in the vicinity of the horizon of a large Sch…
