Invariant manifolds and the response of spiral arms in barred galaxies
P. Tsoutsis, C. Kalapotharakos, C. Efthymiopoulos +1
The unstable invariant manifolds of the short-period family of periodic orbits around the unstable Lagrangian points and of a barred galaxy define loci in the configura…
Universality of Quantum Gravity Corrections
Saurya Das, Elias C. Vagenas
We show that the existence of a minimum measurable length and the related Generalized Uncertainty Principle (GUP), predicted by theories of Quantum Gravity, influence all quantum H…
Three-dimensional numerical simulations of the pulsar magentoshere: Preliminary results
Constantinos Kalapotharakos, Ioannis Contopoulos
We investigate the three-dimensional structure of the pulsar magnetosphere through time-dependent numerical simulations of a magnetic dipole that is set in rotation. We developed o…
Supersymmetry Signals of Supercritical String Cosmology at the Large Hadron Collider
Bhaskar Dutta, Alfredo Gurrola, Teruki Kamon +4
We investigate the minimal supergravity (mSUGRA) signals at the LHC in the context of supercritical string cosmology (SSC). In this theory, the presence of a time dependent dilaton…
Yukawa Corrections from Four-Point Functions in Intersecting D6-Brane Models
Ching-Ming Chen, Tianjun Li, V. E. Mayes +1
We discuss corrections to the Yukawa matrices of the Standard Model (SM) fermions in intersecting D-brane models due to four-point interactions. Recently, an intersecting D-brane m…
Particle interactions with single or multiple 3D solar reconnecting current sheets
A. Anastasiadis, C. Gontikakis, C. Efthymiopoulos
The acceleration of charged particles (electrons and protons) in flaring solar active regions is analyzed by numerical experiments. The acceleration is modelled as a stochastic pro…
