Cosmological Constant
Abstract: Dark Matter and Dark Energy as a Possible Manifestation of a Fundamental ScaleIf we take the idea of the Planck length as a fundamental (minimum) scale and if additionally we impose the Cosmological Constant ($Lambda$) as and infrared (IR) cut-off parameter. Then it is possible to demonstrate that D... read more

Gravity and Yang-Mills Sectors from a Unified Theory and Their Relation with Dark Energy
Speaker(s): Antonino Marciano
Abstract: We propose a new method of unifying gravity and the Yang-Mills fields by introducing a spin-foam model. We realize a unification between an SU(2) Yang-Mills interaction and 3D general relativity by considering a constrained Spin(4) ~SO(4) Plebanski action. The theory is quantized a la spin-foam by i... read more

Quantum fields and Noether charges for kappa-Minkowski
Speaker(s): Antonino Marciano
Abstract: There has been much interest, in the past few years, in the kappa-Poincare'/kappa-Minkowski framework as a possible scenario for a deformation of Poincare' symmetries at Planck scale. I will show how it is possible to give a physical characterization of the concept of quantum symmetries described by... read more
