N=2 SU Quiver with USP Ends or SU Ends with Antisymmetric Matter
Dimitri Nanopoulos, Dan Xie
We consider the four dimensional scale invariant N=2 SU quiver gauge theories with USp(2N) ends or SU(2N) ends with antisymmetric matter representations. We argue that these theori…
The spherical collapse model and cluster formation beyond the cosmology: Indications for a clustered dark energy?
S. Basilakos, J. C. Bueno Sanchez, Leandros Perivolaropoulos
We generalize the small scale dynamics of the universe by taking into account models with an equation of state which evolves with time, and provide a complete formulation of the cl…
Discreteness of Space from the Generalized Uncertainty Principle
Ahmed Farag Ali, Saurya Das, Elias C. Vagenas
Various approaches to Quantum Gravity (such as String Theory and Doubly Special Relativity), as well as black hole physics predict a minimum measurable length, or a maximum observa…
How to observe a non-Kerr spacetime
Theocharis A. Apostolatos, Georgios Lukes-Gerakopoulos, George Contopoulos
We present a generic criterion which can be used in gravitational-wave data analysis to distinguish an extreme-mass-ratio inspiral into a Kerr background spacetime from one into a…
Origin of chaos near critical points of quantum flow
C. Efthymiopoulos, C. Kalapotharakos, G. Contopoulos
The general theory of motion in the vicinity of a moving quantum nodal point (vortex) is studied in the framework of the de Broglie - Bohm trajectory method of quantum mechanics. U…
The pulsar synchrotron: coherent radio emission
Ioannis Contopoulos
We propose a simple physical picture for the generation of coherent radio emission in the axisymmetric pulsar magnetosphere that is quite different from the canonical paradigm of r…
